Cough autoreanimatsiya (CAR) - these are the cases where the person's heart stopped, but he himself supported the re-circulation of the blood cough.
In 2018 it became especially a lot of news on the subject, so in December in the journal Resuscitation published a review of known cases. They were described to the 70s of the last century.
Usually it was in the ICU. Patients stopped the circulation due to cardiac arrhythmia. They were offered as much as possible coughing every 1 - 3 seconds. Since blood pressure could be maintained for 30 - 90 seconds.
A mechanism for increasing blood pressure studied and decided that the meaning of this is, but recommend that such a thing will not be anyone. Because it is very much unreliable.
The fact is that the vast majority of reported cases have been associated with arrhythmias. The popular English-language resources arrhythmia is called a heart attack. It is also called a myocardial infarction.
It may be that people with coronary heart disease during the next attack will ekperimentirovat and lose time. And in the case of a heart attack is very important as soon as you can get medical help. Therefore, cardiologists believe popular articles about the CAR is extremely irresponsible and potentially dangerous.
In my opinion, in our country fashion cough it came in 1996 with the American book "Cardiopulmonary resuscitation" translated publishing practice.
Now the American Heart Association suggests using CAR only if the patient develops an arrhythmia in the background cardiological procedures, catheterization and others. That is when the patient is already under the monitors. And of course no other resuscitative measures are not put off.
If you suddenly became irregular in the heart, then do not experiment, and immediately call an ambulance!
