  1. Values are expressed as mean ± standard deviation. *P ≤ 0.001 – comparison between IPAH and ARDS patients. ARDS, acute respiratory distress syndrome; CI, cardiac index; IPAH, idiopathic pulmonary arterial hypertension; PAP, pulmonary artery pressure; PVRI, pulmonary vascular resistance index; Pwedge, pulmonary artery occlusion pressure; Tc bi fast, time constant of the fast component of the biexponential curve(s); Tc bi slow, time constant of the slow component of the biexponential curve(s); Tc mono, time constant of the monoexponential curve(s).
