To do mouth-to-mouth breathing, it is first necessary to know if the victim is breathing. To do this, place your index finger very close to your nostrils and check for any air.
If not, start mouth-to-mouth breathing as follows:
- If possible, lay the victim on the floor, face up and turn your head slightly back, leaving the airways more free, as shown in figure 1; Open the victim's mouth and observe if there is anything blocking his throat. If it exists, remove it with tweezers, or with your fingers; Cover the victim's nose and take a deep breath; Release all the air in the victim's mouth and watch his chest, which must fill with air and rise, as shown in image 2; If she does not breathe again on her own, repeat mouth-to-mouth resuscitation about 20 times per minute.
Also note if the victim has a heartbeat, resting his ear on the victim's left chest. If they are absent, intercalate 5 mouth-to-mouth breaths with a cardiac massage until the victim breathes again on his own.
