WebSep 28, 2024 · Summary. The main function of the respiratory system is gas exchange (O 2 and CO 2 ). Ventilation is the movement of air through the respiratory tract into (inspiration) and out of (expiration) the respiratory zone ( lungs ). The. physiologic dead space. is the volume of inspired air that does not participate in gas exchange. WebBreathing 100% O 2 can lead to absorption atelectasis and increase intrapulmonary shunting, which further contributes to hypoxemia. Thus, FiO 2 should be kept as low as …
