WebTheye are present within body cavities, and extend into some specific bones to take the place of the bone marrow. This has the added function of reducing the weight of the bone, as they are essentially filled with air. The air sacs create unidirectional flow of air to maximise oxygen extraction and reduce heat production during flight.

WebOct 4, 2024 · The alveolar and extra-alveolar vessels change their resistance characteristics as lung volume changes. It makes sense: at small lung volumes everything is compressed, some of the lung is collapsed and so pulmonary vascular resistance is high because pulmonary arteries are narrowed. WebRestriction was defined as total lung capacity (TLC) less than 80% predicted, and gas trapping on plethysmography was defined as a residual volume (RV) to TLC ratio (RV/TLC) of greater than 45%. A low DLco (corrected for hemoglobin) and DLco with alveolar volume (VA) correction (ie, DLco/VA) were defined as values of less than 80% predicted.
WebResidual Volume (RV) is the air that is left in the lungs after a maximal exhalation, so RV will be estimated today as 1.2 Liters. Capacities, such as Total Lung Capacity (TLC), refer to two or more volumes combined (Figure 7.1).
