Parameters	Patient groups						Upper limit of normal value
	PAH	IPAH	PAH-CTD	PAH-CHD	PoPH	CTEPH
sPAP (mmHg)		^5	^1.4	^3.5	^4		<30-36
Mean PAP (mmHg)	^4	^4.5	^1	^3			<21
Mean RAP (mmHg)		^5	^5	^5	^4		2-6

Note: sPAP: systolic pressure in the pulmonary artery; mean PAP: mean pressure in the pulmonary artery; mean RAP: mean pressure in the right atrium; PAWP: pulmonary artery wedge pressure; CO: cardiac output; CI: cardiac index; PVR: pulmonary vascular resistance; SvO₂: mixed venous saturation; SaО₂: blood oxygen saturation. 1: ; 2: ; 3: ; 4: vs. ; 0: vs. .
