Gas exchange in the lung depends on tidal breathing, which brings new oxygen to and
removes carbon dioxide from alveolar gas. This maintains alveolar partial pressures that …

This review provides an overview of the relationship between ventilation/perfusion ratios
and gas exchange in the lung, emphasising basic concepts and relating them to clinical …

The lung exists to exchange O2 and CO2 between air and blood. Ventilation first carries
inspired air to the alveoli. Then, O2 and CO2 exchange between alveolar gas and capillary …

The ultimate goal of the respiratory system is to exchange oxygen (O 2) and carbon dioxide
(CO 2), to meet the metabolic needs of the body. In order to properly transfer both gases …

The primary function of the lungs is to exchange the respiratory gases, O2 and CO2,
between the atmosphere and the blood. Our overall understanding of the lungs as a gas …

One of the major roles of the lungs is to facilitate gas exchange between the circulatory
system and the external environment. The lungs are composed of branching airways that …

This overview presents the recent progress in our understanding of gas transfer by the lungs
during the respiratory cycle and during breath holding. Different phenomena intervene in …

By far the commonest cause of impaired gas exchange in patients with lung disease is
ventilation‐perfusion inequality. This is a complicated topic and much can be learned from …

Naturally, such a vast topic as pulmonary gas exchange cannot be treated in any balanced
or comprehensive way in this minireview. Rather, we have concentrated on a few highlights …

Carbon dioxide retention in chronic lung disease is often attributed to" alveolar
hypoventilation." This designation is misleading because the patients are usually moving …
