Cardiopulmonary resuscitation (CPR) is necessary whenever the oxygen supply to the brain is insufficient to maintain cerebral function. Oxygen supply to the brain is dependent on :
1. Cardiac output
2. Haemoglobin concentration
CaO2 = Hb g/dl x SaO2 x 1,34ml O2/dl + (PaO2 x 0,003)
3. Oxygen-haemoglobin saturation, which is mainly dependent on respiratory function.
CPR is thus essential in any condition in which cardiac output is critically low.
