HBO Nugget 10

Referring a wound care patient for hyperbaric oxygen therapy requires a commitment of time.  Typically, the patient would require 20 to 40 treatments or “dives,” with 30 being the average amount of treatments. The patient must arrive before the treatment can start to have their vital signs taken and their glucose checked if they are diabetic and also be screened for safety.  Contraband cannot be allowed in the chamber. Recall that 3 things are required for a fire: fuel, ignition source, and an accelerant. For example, street clothes, hand warmers, cell phones, and hairspray are not permitted in the chamber.

Pressurization, or descent, usually takes about 10 minutes. After arrival at the required depth, the standard treatment time is 90 minutes. The patient must then ascend, or depressurize, which again takes about 10 minutes.  Total time in the hyperbaric chamber (monoplace) is usually 110 minutes.  Clearly, the amount of time needed exceeds 2 hours.  However, for many, the benefits of having a wound healed and closing the door to infection far outweigh any time inconvenience.
