It’s a proven fact now, not only by research studies but also by real life data that people around the victim of sudden cardiac arrest are reluctant to do mouth to mouth breaths. The primary cause for this hesitation is that they are afraid of catching diseases from the victims and even those who are trained fear that they could not perform it correctly. The ratio of casualties collapsed in public due to sudden cardiac arrest is only 1 out of 5 who received CPR from a bystander.
According to a publication in The Journal of the American Medical Association on Oct 6, the study has concluded that those adult victims of cardiac arrest had 60% more chances of survival than those who didn’t receive appropriate CPR in a mall or a restaurant. American Health Association is a leader in training individuals for CPR, using mouth to mouth breath as an important part has updated its stance of training after the research in 2008. After investigation it is found that chest-only compressions are more efficient than giving both cardiopulmonary resuscitation and mouth to mouth breath for a patient receiving from a bystander, chest-only compressions are helpful in resuscitating until EMS team reaches the victim of cardiac arrest.
There are several reasons of preference of chest-only compressions
- Giving mouth to mouth breathing while performing CPR halts the circulation of blood to vital body parts like the brain which is regenerated by performing CPR chest-only compressions.
- During the sudden cardiac arrest victims generally inhale oxygen rapidly than usual before they collapse, so they have enough oxygen supply in their blood and need circulation of blood more than the oxygen. In this case chest, the only compression can do a lot in the resuscitation of the victim.
- Chest only compressions do let some of the air to be inhaled passively during recoil of the chest, which although supplies lesser amount, but still, it does provide oxygen.
It’s been a while since proven that those who immediately received shocks with defibrillators soon after they collapsed with a cardiac arrest had survived mostly. This fact has led the availability of AED’s (Automatic External Defibrillators) at several locations, but still performing CPR is better until AED arrives. The rate of compressions should be 100 per minute while performing CPR.
During a study carried out in Japan on 4000 cases in which victims of cardiac arrest were resuscitated by people nearby either with chest-only compressions or with rescue breathing. During the study, it was discovered that those victims who received only cardiac compressions from bystanders had 19.4% better results, in comparison to those who received rescue breath had an outcome of only 11.2%.
Everyone can learn chest-only compressions, but not everyone can learn both breathe relief and chest compressions. This indicates towards comfortability of the person performing CPR; the more resuscitator delivers it well greater are the chances of victims survival.
