My sister in-law had a heart attack today paramedics gave her CPR - she has a collapsed lung - they have put her into a coma - what are her chances? she has had a weak heart and on the wrong side, from when she was born also a whole in her heart. Her parents were told she wouldn t live to 30 she is just 45. So she has done well. She is very over weight and can t exercise or walk too far.
The prognosis depends on how long the CPR was given and after what time the doctors were able to restart the circulation of blood and what are the vitals post CPR (considering an already weak heart).  The more time it took to restart the circulation the worse the prognosis. The reason for comma after CPR can be many, the most important being hypoxic damage to the brain (damage due to lack of oxygen) if that is the case the prognosis is Not good. Giving at least 48 hours post CPR will give us clear idea about the recovery and chance of reversibility of coma. Do send me more details for a more objective evaluation.  Regards
