Analysis of SaO₂ & heart rate from the combined PBG/PBA study
Analysis of SaO₂ and heart rate from the combined PBG/PBA study
Pilots routinely utilize positive pressure breathing to prevent hypoxia while flying at high altitudes. In addition, positive pressure breathing is also exploited to avoid syncope while pilots experience elevated Gz levels. This study evaluates the effects on heart rate and oxygen saturation of transitioning from positive pressure breathing for increased Gz load to positive pressure breathing for altitude. Analysis was performed on previously recorded data taken with permission from Brooks United States Air Force Base in San Antonio, Texas. The findings indicate that while SaO₂ level changes are not statistically significant, heart rate changes are considerable when transitioning to increased Gz level.
