Highlights

• co2 is very permeable through the alveolar capillary membrane so it's easy to change the co2 content even with small amount of lung function (View Highlight)
• there are five mechanisms of hypoxemia: 1) hypoventilation, 2) low environmental pressure of O2, 3) decrease diffusion, 4) VQ mismatch and 5) shunt; plus 6) decrease in mixed venous oxygen saturation can contribute to any of those previous five mechanisms (View Highlight)
• the ideal VQ matching ratio is 0.8 which correspond to the respiratory quotient (View Highlight)
• another effect of an excessively high FiO2 is the risk of reabsorption atelectasis (View Highlight)
