Table 1

Hemodynamic parameters from right heart catheterization.

Hemodynamic parameters (units)	Reference range	Current PAH exacerbation
RAP (mmHg)	2–6	RAP 17/16
PAWP (mmHg)	4–12	14
PAP (mmHg)	20–30 systolic	97/52
	8/12 diastolic
Mean PAP (mmHg)	25	69
CO (L/min)	4–8	3.61
CI (L/min/m^2)	2.5–4	2.03
PVR (woods unit)	0.5–1.1	15

RAP = right atrial pressure, PAWP = pulmonary artery wedge pressure, PAP = pulmonary artery pressure, CO = cardiac output, CI = cardiac index, PVR = pulmonary vascular resistance.
