Right heart catheterization :

BSA: m²Reference: Adult values vary with height and weight; verify the measured/calculated BSA. m² · Hemoglobin: g/dLReference: Typical adult reference: about 7–17 g/dL for this tool; lab- and sex-specific. g/dL

Oxygen consumption: 133.0 mL/min/m²

Blood pressure: mmHgReference: Broad adult reference for this tool: about 80–140 mmHg systolic./mmHgReference: Broad adult reference for this tool: about 50–90 mmHg diastolic. (MAP: ***) mmHg
RA pressure: mmHgReference: Typical RA/CVP: about 2–6 mmHg.Record the mean pressure at end-expiration. CVP should generally approximate RVEDP. mmHg
RV pressure: mmHgReference: Typical RV: about 15–30 mmHg systolic.RVSP should generally approximate PASP./mmHgReference: Typical RV: about 2–8 mmHg diastolic. (***) mmHg
PA pressure: mmHgReference: Typical PA: about 15–30 mmHg systolic.Measure a stable waveform at end-expiration; PASP should generally approximate RVSP./mmHgReference: Typical PA: about 4–12 mmHg diastolic.Use a stable PA waveform and record at end-expiration; PADP should generally approximate wedge. (***) mmHg
Pulmonary capillary wedge pressure: mmHgReference: Typical PAWP/PCWP: about 4–12 mmHg.Confirm a true wedge waveform and measure at end-expiration; wedge should generally approximate PADP. mmHg

Oxygen Saturations:

PA: %Reference: Typical mixed venous PA saturation: about 65–80%.Use a PA sample; unexpectedly high values may warrant checking for a shunt or sampling issue.% · Arterial: %Reference: Typical arterial saturation: about 95–100%.Use a reliable arterial sample or validated arterial oximetry.% via arterial sample
