WebbAssessment of oxygenation is fundamental to the care of patients. Numerous indices of oxygenation have been developed that entail variable degrees of invasiveness, complexity and physiologic underpinning. The clinical reliability of these indices has been questioned. This theoretical study uses a steady-state model of blood gas physiology to study the … WebbAt the breaking point the O 2 content of the alveolar air is about 8% (PO 2 =57 mm Hg) and its CO 2 content is about 7% (PCO 2 = 50 mm Hg). It will be noted that during apnoea there occurs a more significant fall in percentage and tension of oxygen in the alveolar air than rise of CO 2 content and tension. WebbIn atmospheric air, pO2 is about 159 mm Hg. In alveolar air, it is about 104 mm Hg. The partial pressure of carbon dioxide in atmospheric air is lesser than that of carbon dioxide in alveolar air. In atmospheric air, pCO2 is about 0.3 mmHg. In alveolar air, it is about 40 mm Hg.
