Cardiac Output ची गणना कशी करावी
Cardiac Output म्हणजे काय?
Cardiac output is the volume of blood pumped per minute. It's calculated from heart rate and stroke volume, crucial for shock assessment.
सूत्र
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
चरण-दर-चरण मार्गदर्शक
- 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
Worked Examples
इनपुट
HR 100, SV 50 mL
परिणाम
CO = 5 L/min (normal)
Normal cardiac output
Common Mistakes to Avoid
- ✕Confusing cardiac output with blood pressure
- ✕Using SV values from different populations without BSA normalization
Frequently Asked Questions
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.
