The po2 of alveolar air
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. WebbThe compound is found to consist of 69.6% Sand 30.4% N.

The po2 of alveolar air
Did you know?
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). WebbThe alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2):PAO2= (PB−PH2O)FiO2− (PaCO2÷R)where PB is the barometric …
Webb23 nov. 2024 · @Taofeek "the PO2 of Alveolar air reduces to 40 mmHg" - it doesn't. If you stopped breathing for a long time perhaps it eventually would, but not for normal breathing. "the PO2 of blood reduces to 40 after Oxygen diffuses into the tissues, if pressure was constant there should be no reduction" - I never said pressure was constant everywhere.
