Lisa,

Thanks for your question. The catheter on its own does not pose safety risks within the chamber. An important consideration is the utilization of alcohol-based port protectors. To adhere to regulatory standards, hospitals frequently adopt standardized protocols that require disposable disinfection caps on port access sites. These port protectors typically contain a foam or sponge saturated with 70% isopropyl alcohol. ^[1]

NFPA 99 2021: 14.3.1.6.2.3 prohibits the use of flammable liquids, gases, and vapors in Class B monoplace chambers, due to the fire hazard they represent in environments with elevated oxygen levels. ^[2]

Products containing alcohol-saturated sponges or a combination of impregnated chlorhexidine gluconate (CHG) and isopropyl alcohol should be strictly prohibited from entering the Class B monoplace hyperbaric chamber. If a patient arrives at the hyperbaric facility with such a port protector, it must be promptly removed. Subsequently, the port should be safeguarded with an appropriate protector that does not include CHG or isopropyl alcohol during the treatment in the monoplace chamber. ^[1]

I hope this helps. Please let us know if you have any additional thoughts or questions.

Have a great day!

Jeff
