After rescuing the drowning victim to the shore, the patient should call loudly and tap the drowning victim to observe whether the drowning victim responds, if there is no response, it means that the drowning victim is unconscious and unconscious, then observe whether the thorax is rising and falling and whether there is voluntary breathing, if the drowning victim has no voluntary breathing, you should use your hand to Touch the carotid artery of the drowning person, touch whether there is a pulsation, touch 5-7 seconds, if there is no pulsation, you can determine the disappearance of the heartbeat or stop, which are a few basic methods to determine whether the drowning person has normal vital signs. If the drowning person has breathing, pulse, heartbeat, but can not wake up, you should remove the foreign body in the mouth and nasal cavity of the drowning person, keep the airway open, and then the drowning person lying on his side to wait for rescue.
