Alveolar–arterial oxygen gradient — mm ... COPD denotes chronic obstructive pulmonary disease, CT computed tomography, DLco diffusion capacity of the lung for carbon monoxide, GM-CSF ...

Alveolar ventilation is normally between four ... If the response to provided oxygen is poor, it suggests the existence of a severe diffusion-perfusion abnormality or a shunt.

moving air in and out of your lungs (ventilation) oxygen-carbon dioxide exchange (diffusion ... at the end of each bronchiole is a small duct (alveolar duct) that connects to a cluster of ...

In an evolutionary perspective, the size of primitive multi-cellular species was necessarily limited by nutrients' diffusion speed ... that the structure of the alveolar system is indeed optimal ...

Hypoxia associated with an increased alveolar–arterial oxygen difference may be attributable to shunting, a ventilation–perfusion mismatch, or a limitation in pulmonary diffusion. We speculate ...

Dr. Cindy McEvoy will present “Increased Alveolar Volume and Lung Diffusion Capacity in Former Preterm Infants Randomized to Two Extra Weeks of Continuous Positive Airway Pressure (CPAP) ...

These air sacs move oxygen into your blood. Alveolar walls contain surfactant. This is a substance made of fats, proteins, and other substances. This surfactant helps the alveolar walls stay open ...
