Gas exchange asthma
WebLung disease can lead to severe abnormalities in blood gas composition. Because of the differences in oxygen and carbon dioxide transport, impaired oxygen exchange is far more common than impaired carbon dioxide exchange. Mechanisms of abnormal gas exchange are grouped into four categories— hypoventilation, shunting, ventilation–blood flow ... WebGas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues. This article will discuss the principles of gas exchange, factors affecting the rate of exchange, and relevant clinical …
