Police people told that in low body temperature a person can be revived with CPR even after sometime
Cardiopulmonary Resuscitation may not be successful if the body temperature is less than 35oC, said Padma Shri Awardee Dr K K Aggarwal President Heart Care Foundation of India and Honorary Secretary General IMA while giving training a batch of 250 police people from PCR vans here today.
The foundation along with IMA and Delhi Red Cross Society with Delhi Police will bet training 100% PCR staff by 14th August.
In hypothermic deaths, a person can be revived even after hours of cardiac arrest. Only once the body temperature is brought back to normal CPR will be effective.
As per the modern medicine, in cardiac arrest, the brain may not die for the next 10 minutes and during this period, if the heart can be revived, life can be brought back.
The revival of patient during this period can be remembered by the formula of 10: Within 10 minutes of the stoppage of heart (cardiac arrest), if effective chest compressions are given for the next ten minutes with a speed of 100 per minutes (10X10), 80% of the cardiac arrest victims can be revived.
This period can be much longer in hypothermia state. If the temperature of the body is low, the brain may remain alive till the temperature is brought back to normal.
There are instances in literature where a newborn with hypothermia was declared dead but revived in the cremation ground when the environment heat brought his temperature to normal and the pressure on the chest worked like cardiac massage.
