Usually only choking on a mouthful of water will not lead to dry drowning, but the water choked into the lungs needs to be expelled promptly by coughing. First, if an adult chokes, try to remain seated so as not to fall and stimulate the Hegu point of the hand to relieve the symptoms of choking as soon as possible, the adult can lower his head, pound his chest and cough hard to expel the water from the trachea by coughing. Second, if a child chokes, you can assist the child to pat the back, let the child cough hard and discharge the excess water in the lungs, but if it is an infant, you can apply the rotary pat method, that is, one hand holding the baby’s feet to turn the baby upside down, while paying attention to protecting the neck to avoid cervical fracture dislocation, the other hand gently patting the baby’s back, try to choke into the water discharge.
