It is very important to save the life quickly after drowning. Because the human body has very little oxygen stored in the body after breathing has completely stopped, it can only sustain life for 5 to 6 minutes time. If breathing is not restored by this time, then the heartbeat will stop and brain death will result due to lack of oxygen. Therefore, if resuscitation is carried out within 4 minutes after drowning, the chances of success are very high. Statistics show that the percentage of drowning patients who die in 6 to 9 minutes of drowning is 65%, and the success rate of resuscitation can reach 100% if resuscitation is done correctly within 1 to 2 minutes after drowning. Resuscitation immediately after drowning is a most important principle.
