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) CI=CO/BSA |
