Title: [abstract]A CASE STUDY OF A PATIENT EXPERIENCING A MISSED DECOMPRESSION OBLIGATION AFTER BEING TREATED WITH AIR VS. OXYGEN IN A MONOPLACE CHAMBER
Author: Duffy J
Abstract: An 82-year-old comorbid patient was treated for an arterial insufficiency ulcer at 2.5 atmospheres absolute; five-minute air-breaks were ordered at 30-minute oxygen intervals. During the first scheduled air-break, the technician discovered that the air-break equipment was not working, unable to administer the air-break; the technician reduced the treatment pressure to 2 atm abs and completed the 122-minute treatment prior to decompression. The patient went home. Two hours later, during discussions with the chamber manufacturer regarding the malfunctioning equipment, it was determined that the patient was treated with air instead of oxygen. The patient was notified and asked to return to the hyperbaric department for assessment. The patient was asymptomatic for decompression sickness. It was determined after consultation with the USN Dive Tables that the patient had experienced a missed decompression obligation of 34 minutes at 20 fsw Because the patient was asymptomatic for decompression sickness, the patient was treated with a USN Treatment Table 5 without any further complications. An investigation of the occurrence demonstrated a lack of compliance with daily equipment checks, response to gas alarms, consultation with other hyperbaric staff, and communication with the supervising physician. The chamber manufacturer was consulted, and a rather simple engineering solution was implemented to reduce the likelihood of a similar incident occurring.
