Understanding This Calculator

Cardiac Output Formula

Cardiac output is the product of heart rate (HR) and stroke volume (SV). It is typically measured in liters per minute.

CO = (HR × SV) / 1000

  • HR: Heart Rate (beats per minute)
  • SV: Stroke Volume (mL per beat)
  • 1000: Conversion from mL to Liters

Example 1

Resting: HR 70 bpm, SV 70 mL.

  • Calculation: (70 × 70) / 1000
  • 4900 / 1000 = 4.9 L/min

Example 2

Exercise: HR 150 bpm, SV 100 mL.

  • Calculation: (150 × 100) / 1000
  • 15000 / 1000 = 15.0 L/min

How to Use

  • Enter Heart Rate.
  • Enter Stroke Volume.
