Cardiac output is the volume of blood pumped per minute. It's calculated from heart rate and stroke volume, crucial for shock assessment.
Formule
Calculate: CO = HR × SV (in mL)
- CO
- CO/BSA — CO/BSA
- HR
- HR value — Variable used in the calculation
- SV
- SV value — Variable used in the calculation
Stapsgewijze handleiding
- 1Calculate: CO = HR × SV (in mL)
- 2Normal CO ≈ 5 L/min; normalize to body surface area: CI = CO/BSA
- 3Normal CI ≈ 2.5-3.5 L/min/m²
Uitgewerkte voorbeelden
Invoer
HR 100, SV 50 mL
Resultaat
CO = 5 L/min (normal)
Normal cardiac output
Veelgemaakte fouten om te vermijden
- ✕Confusing cardiac output with blood pressure
- ✕Using SV values from different populations without BSA normalization
Veelgestelde vragen
What decreases cardiac output?
Decreased heart rate, decreased stroke volume (due to reduced preload, afterload, or contractility).
How is stroke volume measured?
Echocardiography, cardiac catheterization, or non-invasive methods. Not directly measured from vital signs.
