Webbthe PO2 = 40 mmHg the hemoglobin is at 75% saturation So...you don't really need a high PO2 (greater than 104 mmHg) in the alveolar air or in arterial blood, the hemoglobin (which is carrying most of the O2) is almost completely saturated when the PO2 is only 70 mmHg (you can see this in figure 23.19). Webb13 maj 2024 · • Changes of alveolar gases with altitude. As gas moves from nostrils to the smallest gas-diffusion airways, the sequential addition of water vapour and CO2, reduces the PO2 by about 60 mm Hg. As a result, the PIO2 is an inaccurate starting point for models of oxygen transport at any altitude. ont to sna drive time
