WebMay 31, 2024 · Dynamic compliance measurement. Gas exchange in mechanical ventilation is strongly related to dynamic compliance. If a larger volume of respiratory gas is shifted at the same compliance pressure (i.e., the part of the total pressure distending the alveolar periphery), alveolar gas exchange/turnover improves. Assuming the ventilated … WebThe relationship between ventilation and perfusion is referred to as V/Q, which describes the ratio between ventilation (V) and perfusion (Q) for a particular lung region. Because V/Q is critical to gas exchange and as many pulmonary diseases cause ventilation–perfusion mismatches, it is well worth understanding the effect of changing V/Q on ...
