Normal Cardiac Parameters


Normal Cardiac Parameters

Normal Cardiac Parameters and formulas are used in critical care hospital settings. These cardiac parameters  monitor cardiac conditions and potential life-threatening problems. Montering cardiac parameters in a critical patient guides the physician/APRN in medical interventions appropriate for the patient.


Cardiac Output (CO)

CO=heart rate X CVA Volume

4-8 L/min


Cardiac Index (CI)


2.8-4.2 L/min


MAP (Mean Arterial Pressure)


80-100 mmHg


SVR (Systemic Vascular Resistance)

SVR=(MAP-CVP) x (80)/CO

800-1200 dyne x sec/cm


PVR (Pulmonary Vascular Resistance)

PVR= (PAM-PCWP) x (80)/CO

45-120 dyne x sec/cm


QTc (QT interval)


0.38 -0.42


CVP (Central Venous Pressure)

Right Atrial Pressure

0-8 mmHg


PAS (Pulmonary Artery Systolic Pressure)

20-30 mmHg

PAD (Pulmonary Artery Diastolic Pressure)

10-15 mmHg

PCWP (Pulmonary Capillary Wedge Pressure)


8-12 mmHg

Post MI 16mmHg
