What Researchers Did
Researchers monitored arterial blood gas during hyperbaric air breathing in two mechanically ventilated patients undergoing US Navy Table 6 treatment for cerebral gas embolism.
What They Found
Both patients experienced hypoxemia during the first air breathing period at 1.9 atm abs (192.5 kPa). This suggests that oxygenation monitoring is advisable during air breathing periods for patients requiring 40% or more inspired oxygen before hyperbaric oxygen therapy, especially at lower chamber pressures.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy, particularly those with lung dysfunction or requiring high inspired oxygen, should be closely monitored for hypoxemia during air breathing intervals. This proactive monitoring can help prevent complications and ensure patient safety during treatment.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The primary limitation of this study is its reliance on only two case reports, which limits the generalizability of the findings.
