- VDA/VT = alveolar dead space; QVA/QT = venous admixture; Cqs = quasi-static respiratory compliance; Crs = respiratory compliance (slope of the P-V curve above the lower inflection point); MPAP = mean pulmonary arterial pressure; PVRI = pulmonary vascular resistance index; PCWP = pulmonary capillary wedge pressure; CI = cardiac index.
