Answer
Cardiac output refers to the amount of blood that the heart pumps per minute. It's a crucial physiological measure that reflects the efficiency of the heart in delivering oxygen and nutrients to various tissues and organs in the body. Cardiac output is influenced by factors such as heart rate and stroke volume.
The formula to calculate cardiac output is:
**Cardiac Output (CO) = Heart Rate (HR) × Stroke Volume (SV)**
Where:
- **Heart Rate (HR)** is the number of heartbeats per minute.
- **Stroke Volume (SV)** is the amount of blood pumped by the heart in a single heartbeat.
In simpler terms, cardiac output represents how much blood the heart pumps in one minute, taking into account both how fast the heart beats and how much blood it pumps with each beat.
