Questions and Answers

What is the formula for Cardiac Output (CO)?

  • CO = ESV - EDV
  • CO = SV / HR
  • CO = EDV - ESV
  • CO = SV x HR (correct)

  • End Diastolic Volume (EDV) (correct)
  • End Systolic Volume (ESV)
  • Cardiac Output (CO)
  • Stroke Volume (SV)
  • What is the normal range for Stroke Volume (SV)?

  • 100-150 ml/beat
  • 30-60 ml/beat
  • 150-200 ml/beat
  • 60-100 ml/beat (correct)

    Study Notes

    Cardiac Output (CO)

    • Formula for Cardiac Output (CO): CO = Heart Rate (HR) × Stroke Volume (SV)

    Ventricular Volume

    • End Diastolic Volume (EDV): the final volume in the ventricle at the end of diastole

    Stroke Volume (SV)

    • Normal range for Stroke Volume (SV): 60-100 mL

    Cardiac Contraction

    • Inotropy: the force of mechanical contraction in the heart

    Preload Effect

    • Increase in preload: increases stretch of cardiac muscle, leading to increased contraction force and stroke volume
