Self CPR:
Alternate deep breathing and coughing at every two seconds may save your life during cardiopulmonary arrest particularly when you are alone and nobody is to help you .

Cardiac arrest may be caused by almost any known heart condition. Most cardiac arrests occur when a diseased heart's electrical system malfunctions. This malfunction causes an abnormal heart rhythm such as ventricular tachycardia or ventricular fibrillation.

Cardiopulmonary arrest is the cessation of adequate heart function and respiration and results in death without reversal. Often this condition is found in patients with coronary artery disease.Without oxygen, death can occur as soon as 4 to 6 minutes later. Cardiopulmonary resuscitation (CPR) combines rescue breathing (mouth-to-mouth) and chest compressions to temporarily pump enough blood to the brain until specialised treatment is available. Chest compressions are the priority in CPR.
