Pulmonary artery catheter hemodynamics
Simplified Fick · Estimated VO₂
mPAP: Unavailable
Adult resting references are not treatment targets. Context-dependent indices have no universal reference label.
Needs valid Hemoglobin, Arterial saturation, PA saturation, Height, Weight
Entered CO, or VO2 / [1.36 × Hb × (SaO2 − SvO2)] × 10; saturations in percent
Simplified Fick omits dissolved oxygen. Blank measured VO2 uses 125 × BSA mL/min, so CO remains estimated. Entered CO takes precedence.

Adult resting reference, not a treatment target or severity score. Interpret with measurement quality and clinical context.
Diagnostic context: PH is defined by mPAP >20 mmHg at rest; pre-capillary PH additionally requires PAWP ≤15 mmHg and PVR >2 WU. This is not a severity scale.
