What Researchers Did
Researchers investigated differences in skeletal muscle and subcutaneous tissue gas tensions between chronic cigarette smokers and non-smokers under normobaric and hyperbaric oxygen conditions using mass spectrometry.
What They Found
All tissue gas tensions changed significantly over time (p=0.00001) as pressures and gas mixtures were altered. Significant differences were observed between smokers and non-smokers in unloading muscle nitrogen in both hyperbaric oxygen protocols (Protocol A: p=0.02; Protocol B: p=0.022). Carbon dioxide levels decreased significantly with hyperbaric oxygen exposure but increased when breathing air at 2 ATA.
