     California has been preparing for, and enduring, an exceptionally intense, 'once-in-ten-years', storm (Level 4; not previously seen in the area); –the product of an "atmospheric river" of moisture from the Pacific dumping as much as 12 inches of rain in two days. Those who ascribe to the Boy Scout Motto of 'Be Prepared' filled sandbags, moved goods to higher floors, checked flashlights and radios, filled up gas tanks (gasoline can pump if there's no electricity), and readied themselves to evacuate, or were barred from where they live or public places to which they might have gone.

      Probably, not all efforts were as complete as they should have been. Seldom used lanterns were found with corrosion and dead batteries.  Stock up food and batteries, but forget serious foul-weather gear? Was the car actually packed for evacuation? Was a place to stay planned? Were wallets and important papers sealed against an accidental dunking?

      Medical emergency personnel prepare well for their work: preplanning, checking equipment, reserve supplies, drills to varied scenarios. We should, but don't always (if we're like most people), apply those same skills to our home; our bastion of feeling safe. Often, it seems monumental to make considerable preparation. Certainly, it is if done all at once, or under the compulsion of immediate necessity. "We just grabbed what we could. It all happened so fast!" Taken in smaller bites, incrementally, in stages; it's not so bad or expensive. We can do better planning if the flood level isn't coming in our door.

     Firstly, do you have a communications and family reunion plan. Successful contact will ease everyone's mind. Remember that telephone circuits may be overloaded or destroyed. Think of alternatives, Inexpensive family radios or citizens band may be helpful if distances are short and clear, but may be crowded. Text may get through, as it needs less bandwidth and time. Call distant relatives who may be able to relay for you. If all are at home, action is easier; when the family is scattered, or under the authority of the school's emergency plans (please reread), it may be harder to reunite, or if the first meeting-place is at risk --what is the alternate choice?

     One of the most important steps to take is redundant documentation: identity; money, credit, finances, ownership, documents. Some can be saved on your cellular phone, cloud storage, in pdfs on your encrypted flash drive; each adult and responsible child should have such a flash drive, in case of separation. Have recent family photos for identification by authorities or for posters.  Deeds, mortgages, insurance policies, wills, may be sitting in a safe deposit box. Is there a family cemetery plot; do you have a copy of that paperwork?. If a tornado or earthquake destroys your bank, what then? The bank won't reimburse you on the alleged value of things they never see, and which is at your own risk.

     Trying to recover or replace missing documents is tedious and difficult. A lawyer's office in your town may suffer from the same calamity. Having photocopies or pdfs is invaluable. Remember to include a copy of your Internet password manager. Make photocopies of both sides of your credit cards, so that you can call for replacements, and emergency funds.

      Interior photos and videos should be uploaded to the cloud server, in addition to precious family photos, as they can greatly ease making insurance claims.

      You hope that your healthcare system has copies of your records, but will they be delayed while restoring the system? Think of yourself or loved ones as if they were inbound critical patients to your facility, what information would you want to have in the transfer packet?

      Suppose that you must relocate to a faraway place, as happened with Hurricane Katrina. Do you have copies of school and team physicals, and immunization records, as well as a short-term supply of medications and prescriptions, optical prescriptions? Transcripts and school records would be useful for reintroducing your children, or yourself, back into a new school. Copies of your professional documentation may help you start a new job sooner. Do you have a durable waterproof box for that cellular phone? It, and your computers and devices, are backed up to a cloud server, right? When did you last run a backup?

      Mandatory Evacuation in 1 - 2 hours? Have you planned what you will take in addition to 'must take'? Don't overestimate what to take, where it will fit, how heavy it is to carry, who's fit to carry it. Have you practiced it? (You would do drills at work.) Keep the essential clothes hanging on the rod with the hooks the same way; they can be lifted off and dropped into a plastic storage tub, and go! Don't forget necessary 'security blankets' or dolls. A few favorite treats can refresh exhausted children's psyches.

      Sure, take your GPS; but do you have maps in case there's no signal or the batteries are down? Maps, compass, and flashlights may help get you out of where there's no lights, and signs are washed away. If you're lost or trapped for an extended interval, do you have a known plan with your extended family, that you'll conserve the phone battery by turning on and calling for 5 minutes on every even hour? This helps authorities check for pings if there are working towers. You might need to seek higher ground to get your signal out and may need adequate footwear and clothing to be able to do that. Having signals to flash or wave or prevent others from hitting your car in the ditch, can be helpful if there are overflights or search parties. Plan for extra batteries, and extra devices. Plan for no batteries left; even use a loud police whistle.

      Sometimes, threats from Nature go past our imaginings to life-altering personal risk and regional devastation. Storms, blizzards, monsoon, tornados, typhoons, heatwaves or extreme cold. Flash floods in deserts, or watersheds and alluvial areas. Earthquakes, tsunamis, and volcanism on the Pacific Rim's Ring of Fire, and may occur elsewhere. Secondary hazards may include: loss of power; loss of roadways and transportation; avalanches, rockfalls, and mudslides; tree-falls and downed electrical wires; disruption of 'Just in time' planned deliveries of food and supplies to markets. Just as for many families, homelessness or bankruptcy is only a few failed paychecks away, a few days of hunger and despair can produce looting and lawlessness. Knowledge is power. Know your community's enemy by learning about the most likely problems and known post-event organization for your area.

     If family members are in the Scouting movement, they may be more expert on some of these matters than you, and should be involved in the planning, as they will be trained and responsible stepping up to help. There are several, reasonably-priced, Boy Scout Merit Badge Pamphlets and Handbooks that are incredibly useful, and ideal for family sharing and training. With almost 200 topics, there may well be others to meet your needs. As a Merit Badge Counselor for these and others, I am confident in recommending them to you as you begin your study and preparations.

      I am very thankful for the modern tools and techniques which we now have. I am thankful for having a career of wonderful care at supportive institutions. I am thankful for the family that I have been able to raise and sustain.


What I wish that I had then, that we have now …


  1. POCUS. While Point of Care Ultrasound has made limited entry in prehospital care, largely with physician-led services and some Advanced Paramedics; it has largely been as a proof of concept rather than everyday care. It is training and resource-intensive for prehospital care and indicated treatment may not be feasible, especially in austere environments and economies. Yet, clearly in good hands it delivers real-time anatomic, physiologic, and pathological information that can be life-saving; it has been revolutionary; once having it, one never wishes to regress. Its dissemination in poorer countries might be a better first-step than having one CT or MR scanner.

  2. 911. At the beginning of my career, making an emergency call involved finding a working wired telephone; either knowing and dialing a 7-digit number for each needed service in that jurisdiction, or calling the Operator; explaining the need (if one spoke the national language), or calling a bilingual family member to place the call, —his would sometimes be first to the doctor, then the emergency service; which was connected by telephones or telegraphic alarm systems with their dispatchers. Adding these delays, response times, and in a vertical city -reaching the patient's level meant that there were only two primary rhythms: Asystole, and Sinus (A. Fib, if elderly). There were no coordinated multiple-agency responses.

  3. Really-good 2nd Generation Supraglottic Airways, & Video Laryngoscopy. How great it would have been to have these modalities! In the seventies, there were oral airways; plastic, if you were lucky; metal wire, if you weren't. In the mid-seventies, we began using nasopharyngeal airways. (This was pretty esoteric.)

    We were even more exotic, with 15 mm endotracheal tube connectors fitted in ours. This allowed us to bypass mask facial fit problems by using the nose. If doing what was called "the one-man-band resurrection shuffle" [single person CPR in the back of a moving ambulance], this worked very well, as the bag would stay hanging there on the patient's face. At the ventilation break, without changing kneeling or sitting position, move the hands over for a head-tilt chin-lift that sealed the lips and squeezed the open nostril shut for quick inflations, then resume compressions. Absence of teeth was no problem.

    There was no field endotracheal intubation. Not even an "Esophageal Airway." {By the time we were allowed to do that, we were able to go directly to the Esophageal Gastric Tube Airway. Years later, ETI was finally allowed, but only in extremis with unconscious patients; RSI is still not allowed. There was no protocol for cricothyrotomy: had the need for it occurred, do you follow the rules? If you do one, you might either be a successful hero, or the unlucky schmuck who used to work here. Airways were a highly contentious and polarizing issue: directors and doctors with no field experience; medics with much field experience and no authority to do things already studied; "status-quo politics" remained the order of the day.

    Had we had a good Gen 2 SGA, we might have avoided some aspiration problems, better ventilation in difficult circumstances, and "conduit intubation" might have been the next step. Video Laryngoscopy might have lessened concerns about laryngoscopic intubation, or been a back-up for the difficult intubation.

  4. Pulse Oximetry & End-Tidal Capnography. Wow. How useful these would have been to let us know how well the patient was oxygenating and ventilating! These indices would have reinforced the clinical decision progress and avoided bad outcomes from unsuccessful estimates. So much more than just a BP cuff and a rhythm monitor.

  5. Disposable BVMs (one at every bedside). Yes, there's a crash cart —at the end of the ward's hallway from me. Meanwhile, the patient has just returned from a scan and had a seizure in front of you because his brain is speckled with contrast; post-ictus, he's apneic despite airway measures, and now one must give mouth-to-mouth because there's no bag at the bedside … see what I mean?

  6. Intraosseous Infusion. Not as often resorted to promptly, as it should be. An elderly lady in cardiogenic shock (BP 60/40) with no veins, I was lucky to get a 24-gauge PIV into the back of her wrist. It was all she had.

  7. GPS, Mobile Data Terminals, and Cell Phones. There were times that units were delayed or lost on calls, relying upon local knowledge and paper maps. In foggy or white-out conditions, one might not even see the curbs or intersections, and be dazzled by the flashing lights. Confusion might arise from similar or sound-alike names, the same name on a street, avenue, drive, or court.

    The isolation from having only two-way limited range radio, and no alternate means unless a pay telephone could be found, is not well-understood now. Once, while taking a patient to the hospital, Dispatch radioed us to call ASAP (radio rules didn't allow explanation). By the time that we delivered the patient and called, the five-minute radio-station contest call-back window had elapsed, and I did not win the brand-new car for which they had called my name. This was a sad blow for a poor young medic and family-man whose cars were very old and no money to spare.

All of The Editors, The Publisher, and Staff of Advanced Emergency Nursing Journal wish you a very happy time of thanksgiving and holiday celebration.

Recurring clinical situations and personal interactions may need an astutely apt phrase or bon mot. It's good to have a mental library of successful phrases to use again. 

For example, instructions for the peak flow meter can be confusing. Most people try to "blow-blow-blow" as if for birthday candles. Say that the needle is "like a highway patrol speedometer –it flies up to your fastest speed and stays there" may get a laugh and a better performance. 

  • Sharing one's own allergy problems, "I feel like my Life is attached to my nose!" shows sympathy and empathy.

  • The acute-on-chronic respiratory distress is eased in hearing "You know, ordinary people don't realize what a privilege it is to draw an easy breath." {Let me help position you to breathe with less work, and get you some treatments to help."} {"What do you need most, right now, to help you feel better?"}

  • The person straining with back pain will understand "there's an old song with the line 'Every little movement has a meaning all its own!"  While the reference is not the same, the emphasis on movement is relevant to the present reality.

  • A silly pun such as "needing a good understanding" highlights the importance of a good footing.

  • Novices with crutches tend to look at the floor and their feet which makes them off-balance. Remind them that in diving "the body follows the head; --if you look at the floor, you'll end up on the floor."

  • Persons dwelling on their symptoms, or if you're cautioning about a potential side-effect can be told: "But, you don't have to pay any attention to that and don't need to remember it … 'these are not the droids that you're looking for'" will remind them of Star Wars and that your 'Jedi Mind-Trick' is fun and that they may safely not remember.

  • If more emphasis is needed, or you wish to enhance amnesia as wakening from sedation occurs, say again they don't need to remember, then add "just forget to remember, and remember to forget "  This creates a psychological double-bind that loops itself creating confused 'forgettery'.

  • When doing a shoulder pull-down to see C-7 on x-ray, decrease the muscle tension with visualization of walking through the airport carrying heavy bags (no wheels) and you're staying tall to carry them but your arms are stretching l-o-n-g-e-r … "

  • Not sure which way the differentiation will go? Politely stall with "We'll know more when certain tests have been done." This also helps induce buy-in to the plan by the patient and family.

  • Those anxious prognosis questions can be given assurance as my surgeon grandfather did with "you're doing as well as can be expected considering the circumstances." This non-committal phrase can be fine-tuned with different tone and affect to either be encouraging or cautionary.

  • "How am I doing, Doc?" can get a hearty rejoinder "Why, you're doing the best that you possibly can!considering). "And, I expect that with a little more rest and medicine, you'll be feeling better yet." "How soon, I wonder, do you think you'll be able to feel that way?" " I imagine that you'll want it to be soon." This puts into play the powerful forces of expectation of a positive outcome.

  • Have some simple accurate descriptions of pathophysiology and therapy. E.g., "The heart isn't pumping out all the blood that it receives, so it backs up like traffic at the toll gate, so the liquid part is oozing out into the lungs." "No, it's not really a 'blood-thinner' like paint thinner, it just slows down the clotting a little bit so that it's less likely to sludge up in tight spaces." 

  • You and the patient are working with different mental lists during history-taking and review of systems. Avoid important omissions or kept secrets and anxieties, with a kind and trustworthy: "Tell me, now, anything that you haven't yet told me." If you've established a good rapport, and a yes-series or positive responses, then you will likely get some useful replies.

  • Every good clinician will develop, over time, a personal 'patter' or internalized ready answers, ready questions, and ready assurances appropriate to many situations. You, too, should definitely do so. 

The key is to be warm, engaging, cognizant of present difficulties yet optimistic and good-natured as to outcome and how to get there. If it comes from the heart, it will be received and felt in the heart.

Readers of this blog may have read of the death of Dr. Peter Josef Safar in 2003, who is often called "The Father of Cardiopulmonary Resuscitation," or noted citations of his work in articles written and references given by me here at and the Advanced Emergency Nursing Blog. 

Truth to tell, Peter Safar was not only justifiably given his many accolades, he is one of my personal heroes: inspiring and modelling a life-long devotion to the resuscitative arts; a belief that these skills are needed by all and that they are capable of learning it; and showing how to lead a life worth living.

I was pleased and excited when a Twitter reference, {Haney Mallemat ‏@CriticalCareNow Sep 7 Great piece of Resus history  Thx @expensivecare …this was obviously pre-IRB #FOAMcc #FOAMed}, indicated a YouTube video was available: Respiratory Resuscitation Techniques by Peter Safar, MD. It is a 11:39 minute film, by Walter Reid Army Institute of Research Production of experimental research done by Peter Safar, MD, and associates, at Baltimore City Hospital's Department of Anesthesiology.  

Here is the opportunity of seeing and hearing one of the pioneers of mid-20th Century resuscitation research that put artificial respiration and later closed-chest cardiac compressions on a sound and successful basis of research, testing, teaching, and evaluation of results.  

Safar was not the first, or only, researcher, but his ongoing enterprise, organization, and promotion, co-opting newly-found allies around the world created a phenomenal success that saved an uncountable thousands of survivals world-wide.  

Safar's work, in a series of studies and papers,

  • validated manual methods of opening the airway, in use by anesthesiologists but relatively unknown outside the operating room, as effective and able to be taught and used by lay people.

  • tested and compared the then-common manual (push-pull) methods of "artificial respiration," and found them to be ineffective, prone to failure by not attending support to the airway and volumes "breathed" incapable of transiting the "dead air space."

  • established that exhaled air was a satisfactory gas for resuscitation.

  • demonstrating that unconscious and paralyzed volunteers, without a breathing tube, could be sustained, by lay public rescuers of different ages and stature, for long periods. By rendering the volunteers unconscious and paralyzed by curare, they had the flaccid weakness of an apneic victim, and were dependent on the "rescuers" to keep them alive.

  • Consistent attention was given to the teachability and practicability of recommendations for the public so that it would be accepted readily and used.

  • His research and demonstrated superiority of method was so remarkable that authoritative bodies made mouth to mouth rescue breathing a universal recommendation in approximately a year's time. 

Brief Summary of Life Acheivements by Safar:

  • Too numerous to count; consider the following:

  • Established academic departments of anesthesiology, independent of Surgery.

  • Founded first ICU that was multi-disciplinary.

  • Research: an integral function of anesthesiology department.

  • Established "think-tank" laboratory devoted to resuscitation.

  • Many International projects, thinking, research, dissemination, with global viewpoint including the Soviet Union and "Iron Curtain" countries.

  • Validation of methods of controlling the unprotected natural airway; comparisons of methods of artificial respiration, validating mouth-to-mouth as the most effective means, training and popularizing mouth-to-mouth, and linking and coordinating external cardiac massage (the Johns Hopkins Group) to be Steps A, B, & C of CPR.

  • In collaboration with Asmund S. Laerdal, and Dr. James Elam, led to development and adoption of "Resusci Anne" as a training mannequin.

  • Helped establish the Freedom House ambulance with paramedic level care.

  • Expanding focus of resuscitation to include the brain: CPCR; CardioPulmonary Cerebral Resuscitation.

  • Research into post-arrest after-care, therapeutic hypothermia, reanimatology.

  • Support of prevention activities to lessen the need for resuscitation.

  • The recurring Wolf Creek Conferences on Cardiopulmonary Resuscitation, organized in conjunction with Jude and Elam, served as a pattern for summit meetings of CPR and the ILCOR and AHA scientific meetings of our time.

  • Promotion of a global approach to disaster management, firstly in "The Club of Mainz," then in the World Association for Disaster and Emergency Medicine.

  • Named author of more than 1400 articles; and ten books listed by the Library of Congress.

"The crowner hath sat on her and finds it
Christian burial." …
"But is this law?"
"Ay, marry, is 't—crowner's 'quest law."
Hamlet. Act V, scene I

[Text from Folger Shakespeare Library]
[Audio recording of Dramatic Reading; Chapter Vox]
[Video recording of Act V, scene1]


Most deaths that are brought to, or occur in, an emergency department will require, at least, discussion with the local Coroner or Medical Examiner. This official inherits the powers of a very old and distinctive office; that of the Crowner or "King's Man" begun by the Normans who had conquered England as their grip and control consolidated.

"After the Norman Conquest, to deter the local communities from a continuing habit of killing Normans, a heavy fine was levied on any village where a dead body was discovered, on the assumption that it was presumed to be Norman, unless it could be proved to be English. The fine was known as the 'Murdrum', from which the word 'murder' is derived and, as the system developed, many of the early coroners' inquests dealt with the 'Presumption of Normanry' which could only be rebutted by the local community, and a fine thus avoided, by the 'Presentment of Englishry'." [Coroners Society]

King Richard I (the Lionheart) needed vast sums of money for the Third Crusade, operation of the kingdom, and for his ransom fro m Duke Leopold of Austria.  Crowners looked for "Treasure Trove", and offenses for which properties or fines could be forfeit to the Crown, in contrast to the local magnates who were Sheriffs and often corrupt. [Gross]

So why, in this era, should we still need an ancient office? Wherever the globe once showed red for the British "Empire upon which the sun never sets", there are Coroners who are now independent judicial officers to rule upon the identification of persons found dead and determine the cause and manner of death. These medicolegal investigations have value to not only find crime or negligence, but now also to determine public health problems and to teach the living what may be learned of their disease or modus exitus.

Despite the proliferation of "police procedural" and criminalistics shows on television, there is no guarantee that any particular locale or case receives the "CSI effect." The ideal is a fully funded Medical Examiner's department when the incumbent or staff are board-certified Forensic Pathologists. The other extreme is when a layman has been lucky in the election, but then works without training or hiring those who are competent; sometimes, autopsy services will be outsourced. In some locales, the Coroner's Office has, for economy, been combined with the Sheriff's Office or upon a local prosecutor. Regardless, there are an insufficient number of qualified forensic pathologists to assume office everywhere. [PBS]

It is good to know the local resources and capabilities, an in-service presentation could help in this respect, and an understanding of when the Coroner/Medical Examiner has jurisdiction, and the procedures to follow to preserve the patient and any evidence.

My experience has been with metropolitan jurisdictions with a Medical Examiner, and with California law, which will be used here for an example.

A Coroner may elect not to investigate a notifiable case in several circumstances. E.g.,

  • Upon discussion with the primary physician finds that death was expected from known pathology, the physician has recently seen the patient, and the physician is able to certify the cause of death.
  • The Coroner determines that the medical care during the final illness has sufficiently elucidated the cause and manner of death to exclude other actionable investigational requirements (by surgery, scans, etc.).
  • The cause and manner of death are sufficiently obvious from known facts or death scene investigation as to make it unnecessary.

Contrariwise, the Coroner may assert jurisdiction when perhaps not suspected from superficial appearances, if the cause of death (toxicity) may suggest a criminal agency, occupational exposure, or potential negligence requiring his action, or if the primary physician is unable to certify the cause of death.

Reportability, or those cases in which the Coroner has jurisdiction and must be notified upon declaration of death –whether the Coroner chooses to pursue an investigation or not, typically includes: [Los Angeles Coroner]

Reportable deaths to the Medical Examiner-Coroner
Deaths Requiring a Decision

Certain types of cases not listed in the State Law but which often pose problems or are difficult to evaluate, should be reported to the Coroner for a decision. These include, but are not limited to the following:

·        Persons dying within 24 hours of admission to the hospital, or not medically attended by a physician within 24-hours of the time of death, unless the attending physician has established a natural cause of death.

·        All deaths occurring in operating rooms, during therapeutic or diagnostic procedures or as a result of complications of these procedures (postoperative, e.g., wound infections) or when the patient has not regained consciousness after an anesthetic should be reported.  These are not all Coroner's cases unless the death is known or suspected as being due to misadventure during the surgery, therapy, procedure or anesthetic. These cases are often difficult to evaluate and should be referred to the Department of Medical Examiner-Coroner for a decision. The surgeon or physician with the most knowledge of the circumstances should report the death. The deaths occurring within 24 hours after surgery should also be reported.

·        All deaths in which the patient is comatose on arrival and remains so throughout his/her hospital care unless the cause of the coma has been definitely established as due to a natural disease.

·        The death of an unidentified person will be accepted as a Coroner's case. It is acceptable for the treating physician to opine a cause of death for an unidentified person who dies from a natural disease process. After the death is reported, the Coroner will attempt to identify the decedent. All efforts to identify the decedent by hospital staff, law enforcement agencies or social service agencies should be well documented in the medical records. The cause of death opined by the private physician will be used by the Coroner for the official death certificate. Do not place the name "John/Jane Doe" on the signed death certificate.

·        All deaths involving hip fractures if the attending physician believes the fracture caused or contributed to the cause of death.  If the fracture is to appear anywhere on the death certificate, the certificate must be completed by the Department of Medical Examiner-Coroner and not by the attending physician.

·        All deaths in which an injury or an accident is the cause or a contributing cause regardless of how distant or remote in time or place the accident or injury may have occurred. This includes subdural hematomas, comas, paraplegia, quadriplegia, fractures and seizure disorders, regardless of the time interval between the injury and death.

All cases known or suspected as coming under the jurisdiction of the Medical Examiner-Coroner should be reported immediately to (323) 343-0711. The family or next-of-kin of the decedent should not be approached for permission for an autopsy prior to clearance from the Coroner's office. Removal of tissue from Coroner's cases for scientific or transplant purposes MUST NOT be performed without prior approval of the Coroner, regardless of prior next-of-kin authorization.

The Medical Examiner-Coroner shall have discretion to determine the extent of inquiry to be made into any death occurring under natural circumstances and falling within the provisions of the law. If such inquiry determines that the physician of record has sufficient knowledge to reasonably state the cause of a death occurring under natural circumstances the Coroner may authorize the physician to sign the certificate of death. In all other instances, the Coroner or his appointed deputy shall personally sign the death certificate.  The decision as to whether a death is in fact a Coroner's case rests with the Coroner.  If it is determined, after appropriate evaluation, that the death is not a Coroner's case, it then becomes the responsibility of the attending physician to issue the death certificate.

According to Health and Safety Code 102825, the physician and surgeon last in attendance, or in the case of a patient in a skilled nursing or intermediate care facility at the time of death, the physician and surgeon last in attendance or a licensed physician assistant under the supervision of the physician and surgeon last in attendance, on a deceased person shall state on the certificate of death the disease or condition directly leading to death, antecedent causes, or other significant conditions contributing to death and any other medical and health section data as may be required on the certificate. He or she shall also specify the time in attendance, the time he or she last saw the deceased person alive, and the hour and day on which death occurred. This must be done within 15 hours after the death.  With increasing demand for tissue for transplantation, families consent for organ donation more often.  Many of our decedents are tissue donors (heart valves, cornea, skin, bone). It is therefore important that cases are reported in a timely manner and medical records are available at time of release or removal. 

{End, lengthy quotation of Los Angeles Coroner instructions}


In all emergency department cases, it is best to leave in all lines, airways, devices, etc., and contact the Coroner's representative immediately. No "practice procedures" should be done. Wounds should not be washed. All belongings and potential evidence should be appropriately bagged, sealed, labeled, and delivered via chain of custody. Surfaces or tissues with organic contamination should be in paper bags to preclude a "hot-house environment" that may degrade the usability of the material. Objects without organic contaminants may be within plastic bags; when in doubt, ask the Coroner's or Police investigator for advice. Arrangements should be in place for providing medical, imaging, and other records to the Coroner.

In all cases where the Coroner has jurisdiction, and the family claim religious or other scruple regarding death, the remains, or any investigation, any decision is that of the Coroner who will prevail, but will often accommodate insofar as possible given the needs of the case. Advise the Coroner's representative of what circumstances are known, and they will make any necessary statements to the family.
