Airway obstruction is a fatal clinical emergency. For mild airway obstruction, if the patient is conscious, someone else can cooperate to take the back percussion method. For severe airway obstruction, if the patient is unconscious, call the emergency number in time. While waiting for the arrival of ambulance, except for pregnant women and other special people who cannot press the abdomen, their family members can make the patient expel the foreign body in the body by rapid impact on the abdomen. The key to first aid for airway obstruction is to lift the obstruction and restore ventilation. Mild airway obstruction: In mild airway obstruction, the patient is clearly conscious and can cooperate with the rescuer, so it is usually necessary to take back percussion and percussion with the palm root between the two shoulder blades on the patient’s back to help the patient expel the foreign body from the airway. Second, severe airway obstruction: 1, mostly used for food, foreign objects accidentally stuck in the throat caused by airway obstruction, patients can take self-help methods, first back against the wall, with one hand into a fist, the fist eye placed in the position of two horizontal fingers above the navel, the other hand to hold the fist, from the bottom upward impact on the abdomen, try to discharge the foreign body; 2, their own inability to discharge the foreign body, timely seek the help of others, rescuers in the back with both arms Around the patient’s waist, one hand clenched fist, thumb side below the thorax, above the navel position, the other hand to grab the fist, rapid upward impact compression abdomen, repeat the operation until the foreign body is discharged. If the patient has lost consciousness, can take the supine position, the rescuer riding across the hip, hands folded, the root of the palm in the lower hand placed below the thorax, belly button on the position, rapid impact compression abdomen, repeated operations until the foreign body is discharged. If pregnant women or obese people, the abdomen can not be pressed, you can also press the lower part of the sternum, can make the thoracic pressure suddenly increased, to achieve the effect of foreign body discharge; 3, for infants and young children, let the children sit with their backs on the legs of the rescuer, and then use both hands index and middle fingers, forcefully squeeze the upper abdomen of the child to the back and up, press and then relax, you can also put the child flat on his back, the rescuer with above method of stamping; 4. If it is the sequelae of cerebrovascular disease or the elderly who are bedridden for a long time, the airway obstruction is caused by poor sputum discharge, this situation should be sent to the hospital immediately, and generally requires tracheal intubation and mechanical ventilation, and then a negative pressure suction device connected to a suction tube is used to enter the deep part of the patient’s airway to suck sputum, which needs to be done under the operation of a doctor; 5. If it is the airway obstruction caused by laryngeal edema, it also needs to be sent to the hospital to release the obstruction by tracheal intubation, cricothyrotomy, or emergency tracheotomy.
