SBP = systolic blood pressure (systemic), DBP = diastolic blood pressure (systemic), MAP = mean arterial pressure (systemic), Q = cardiac output, SV = stroke volume, PCWP: Pulmonary Capillary Wedge Pressure, SaO₂ = arterial oxygen saturation, DL_CO = diffusing capacity of the lung for CO, DL_NO = diffusing capacity of the lung for NO, D_M = diffusing capacity for the entire lung membrane, V_C = pulmonary capillary blood volume. Data reported as mean ± SD.
