Oxygen delivery to the tissues

The quantity of oxygen made available to the body’s tissues in one minute is known as the oxygen delivery and is equal to the cardiac output x the arterial oxygen content.

Oxygen delivery (mls O2/min) = Cardiac output (litres/min) x Hb concentration (g/litre) x 1.31 (mls O2/g Hb) x % saturation

In the normal adult this works out as: 5000ml blood/min x 200mlO2/ 1000ml blood = 1000ml O2/min.
