WebbThe pCO 2 ( partial pressure of carbon dioxide) will be lesser in the atmospheric air compared to that in the alveolar air. In atmospheric air, pO2 is about 159 mm Hg. In alveolar air, it is about 104 mm Hg. In atmospheric air, pCO2 is about 0.3 mm Hg. In alveolar air, it is about 40 mm Hg. Webb17 jan. 2024 · At the peak of Mount Everest (at 29,000 feet), the PO2 is only 42 mmHg. As one descends below sea level, as in ocean diving, the total pressure increases by one atmosphere for every 33 feet. At 33 feet therefore, the pressure equals 2 x 760 = 1,520 mmHg. At 66 feet, the pressure equals three atmospheres. slyman brothers o\\u0027fallonWebb8 nov. 2024 · When the body is functioning normally, PaO2 is between 75 and 100 mmHg (at sea level). 5 A result in this range means a sufficient amount of oxygen is flowing from the alveoli to the blood. If your PaO2 is below the normal range, that is not the case. Lung diseases and breathing problems can increase the risk of developing low PaO2. solar system elementary project
