Stroke volume
Volume of blood pumped from the left ventricle per beat.
Tidal volume
The amount of air a person inhales during a normal breath
Cardiac output
The amount of blood the heart pumps through circulatory system in a minute.
To calculate cardiac output
Heart rate x stroke volume.
Minute ventilation
Totally volume of air entering the lungs in a minute.
Average is 6litres per min
To calculate
Breathing rate x tidal volume =minute ventilation.
