Letters to the Editor: Letters & Announcements
With regard to the letter by Davis et al.,1 the Rusch Flexi-Set is designed and tested for compliance to requirements for tracheal tubes and tracheal tube connectors as per ISO 5361:1999. Annex B from these requirements includes a test method for cuffed tube collapse. We confirm the compliance of the Rusch Flexi-Set to this standard.
In addition, the Instructions for Use for the Rusch Flexi-Set Cuffed endotracheal tube state that the clinician should “inflate the cuff slowly with the minimum amount of air required to provide an effective seal.”
We remain committed to complying with ISO standards and with helping clinicians ensure patient safety through the proper use of our products.
