What 5 reasons CPR may be used?

I only know four: * Unconscious * No breathing, or extremely irregular or agonal breathing, Cheyne-Stokes respiration, etc. * No circulation ---OR--- * Obstructed airway and the victim is an infant, pregnant or obese (i.e. too large to get your hands around to perform a Heimlich manuver). Many indications exist for CPR,these include

* Dead cases,where no pulse and no breathing can be detected * Drug overdosage * Drowning * Poisoning

* Non-fatal cardiac arrhythmia

* Shocks and seizures.
