Abstract:
|
The degree of hypoxia manifest by airline passengers during flight is not well-characterized. The relationship between age and PaO2 at sea level (PaO2 sl) and between PaO2 alt and PaO2 sl, PCO2 at sea level (PCO2 sl) and pulmonary health status were investigated using linear regression techniques to analyze previously published data. In persons with normal pulmonary health, the relationship between PaO2 sl (mm Hg) and age (years) was PaO2 sl = 105.9 - 0.44 * age (R2 = 0.582, MSE = 25.314); PCO2 sl (38.1 ± 2.8 mm Hg) was not related to age over the range 18--75 years. In persons with chronic obstructive lung disease (COPD), neither PaO2 sl (78.2 ± 11.3 mm Hg) nor PCO2 sl (40.5 ± 5.7 mm Hg) were related to age (77.0 ± 9.0 yrs). The relationship between PaO2 alt and PaO2 sl, PCO2 sl and altitude (feet) will be described.
