Webb28 jan. 2024 · Final Thoughts. The ventilation-perfusion ratio is the amount of air that enters and leaves the lungs compared to the amount of blood flowing to the lungs. A V/Q mismatch occurs when this ratio is not balanced, which can be caused by a variety of factors, including hypoxemia, airway obstruction, and circulatory problems. Webb1. Document the degree of resolution of pulmonary embolism. 2. Quantify differential pulmonary function before pulmonary surgery for lung cancer (1–3). 3. Evaluate lung transplants (4,5). 4. Evaluate congenital heart or lung disease such as cardiac shunts, pulmonary arterial stenoses, and arteriovenous fistulae and their treatment (6). 5.

Webb5 juli 2024 · Ventilation-Perfusion Ratio. The ventilation rate (V) refers to the volume of gas inhaled and exhaled from the lungs in a given time period, usually a minute. This is calculated by multiplying the tidal volume (volume of air inhaled and exhaled in a single breath) by the respiratory rate. In an average man, the ventilation rate is roughly 6L/min.
