To calculate the Cardiac Output (CO):
\[ CO = \frac{\pi \times (LVOTD / 2)^2 \times VTI \times HR}{1000} \]
Where:
Cardiac output is the volume of blood the heart pumps per minute. It is a critical parameter in assessing cardiac function and is used to diagnose and monitor patients with heart conditions. Cardiac output is determined by the stroke volume (the amount of blood pumped by the left ventricle of the heart in one contraction) and the heart rate (the number of heartbeats per minute).
Given:
Using the formula:
\[ CO = \frac{\pi \times (2 / 2)^2 \times 20 \times 75}{1000} = 4.71 \text{ L/min} \]
The cardiac output is 4.71 L/min.
Given:
Using the formula:
\[ CO = \frac{\pi \times (2.5 / 2)^2 \times 25 \times 80}{1000} = 9.82 \text{ L/min} \]
The cardiac output is 9.82 L/min.
