What does cardiac input mean?

Cardiac input, often referred to as cardiac output, is the volume of blood the heart pumps per minute. It is a key indicator of heart function and overall cardiovascular health, typically measured in liters per minute. Cardiac output is determined by two main factors: stroke volume (the amount of blood ejected by the heart with each beat) and heart rate (the number of beats per minute). Maintaining adequate cardiac output is crucial for ensuring that organs and tissues receive sufficient oxygen and nutrients.
