What Researchers Did
Researchers measured arterial oxygen tension (PaO2) at atmospheric pressure in ten healthy volunteers exposed to hyperbaric oxygen using an automated blood gas analyzer.
What They Found
They found that measured PaO2 correlated strongly with calculated alveolar O2 tension (r2 = 0.97), and after deriving a correction factor, the correlation improved to r2 = 0.98. These normobaric measurements in ten volunteers compared favorably with traditional PaO2 measurements made within walk-in hyperbaric chambers.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A primary limitation is the small sample size of ten healthy volunteers, which may not fully represent the diverse patient population receiving hyperbaric oxygen therapy.
