This is a big Myth an Urban Legen, proved absolutely wrong by medical specialists.
The email believed to be origined in 1999 from a cradiologist.
But in my studies of basic medical sciences during undergrad years and during post grad years i Have never heard of this kind of manouvre.
The so called coughing and deep breathing is termed "COUGH CPR" in cardiology and it is advised only in case of abnormal heart beat arrest that too in supervised indoor facilities.
By deep breathing and coughing we stimulate our vagus nerve which supplies the Diaphragm and helps regulate the Cardiac beat rate.
It is not at all helpfull in routing Heart attacks or Acute Myocardial Infarction as we call in medical sciences.
AMI (heart attack) occurs due to decreased supply of blood to the heart muscles so that there is ischaemia of the muscles which causes following symptoms to appear :
Chest Pain
Compression sensation of chest
Pain radiating to Left shoulder and arm
Breathlessness
and if more severe
Unconsciousness and Cardiac Arrest.
Proper Steps to Take when such situation arises :
Call emergency number immediately. (100 and 108 for India, 911 for USA, 08 and 112 for other countries)
Ask for help.
If you are nearby and you see someone sufferring and if you know the
CPR start it immediately on the unconscious patient (Not on conscious patient)
Let fresh air come in.
Loosen the cloths of the person.
There are medicines which can help for short period of time but I am not spelling them here for the sake of patient safety.
As the heart attack if severe and renders patient helpless it can turn out to be fatal, so if you are one of the high risk person then get regular checkup and follow your physician`s advise to avoid emergency.
Hope FEzens will spread the true information and stop the wrong message going forward.
