Because a lot of water, vomit, etc. enter the respiratory tract during drowning, causing airway blockage.

So, the important step before CPR is to "open the airway" problem: How to deal with respiratory obstruction

Traditional water control treatment often has a poor effect that is "thankful" and delays the favorable opportunity for cpr.

Use Hai's technique to effectively solve this problem of "opening the airway".

The method is to use the Hai's impact squeezing method to remove the moisture in the trachea through the mouth, and then immediately perform CPR.

Thirty seconds later, with a wow, the patient spit out a ball of sticky stuff from his mouth.

Sure enough, the airway was blocked.

Su Yang immediately cleared his respiratory tract and had a resuscitation of cardiopulmonary resuscitation.

Another minute later, the drowning person still had no consciousness, consciousness, breathing, heartbeat, and no large artery pulsation;

Su Yang continued to rescue him but did not give up.

Generally speaking, the mortality rate for drowning for 6 to 9 minutes is 65%, and the mortality rate for more than 25 minutes is 100%.

So in general, if CPR is ineffective for 30 minutes, you can give up. Of course, in reality, there are also cases of persistence in the practice of unhanded cardiopulmonary resuscitation for a long time and not giving up easily. The final successful example was that Su Yang personally saw a case of resuscitation for a long time in Southwest Defense Medicine, Volume 21, Issue 7, Volume 21, No. 7 of Southwest Defense Medicine, Volume 21, 2011. The doctor performed CPR for unhanded for 70 minutes, which allowed the patient to breathe independently.

After Su Yang had another minute of cardiopulmonary resuscitation, the cyanosis of the drowning person gradually improved to rosy, the pulse gradually returned to normal from weak to normal, the breathing returned to 78 times/min, coughing, consciousness and consciousness recovered.

At this point, the rescue was successful!

Soon, Su Yang came out of the system training room and returned to reality.
Chapter completed!
