1. The rescuer stood behind the asphyxiated person, with his legs apart to form a tripod.
2. Surround the suffocating person from the back, and put your hands on the abdomen of the suffocating person (on the navel under the sternum)
3. Make a fist with both hands, and the center of the fist will squeeze the abdomen of the asphyxiated person inward and upward.
4, pay attention to the extrusion to be fast and powerful, you can quickly squeeze 5 times to see the reaction of the suffocating person.
Heimlich first aid method is introduced as follows:
Acute airway foreign body obstruction is not uncommon in life, because patients can't breathe after airway obstruction, and may die unexpectedly due to lack of oxygen. Heimlich maneuver, also known as Heimlich maneuver, was invented by American doctor Mr. Heimlich.
In 1974, he first successfully rescued a patient who was suffocated by food blocking the respiratory tract. Since then, this method has been widely used around the world, saving countless patients, including former US President Ronald Reagan, former new york Mayor Ed, and famous actress Elizabeth Taylor. So this rule is called "the embrace of life".
People's lungs can be imagined as a balloon, and the trachea is the balloon's mouth. If the gas nozzle is blocked by foreign matter, you can squeeze the balloon by hand, and the air in the balloon will move upward under pressure, thus washing away the foreign matter blocking the gas nozzle. This is the physical principle of Hayden's abdominal impact method. The rescuer hugged the patient and suddenly put pressure on his upper abdomen, forcing him to sink.
The sudden rise of diaphragm will make the patient's chest pressure suddenly rise. Because the chest is closed and the trachea has only one opening, the gas in the chest trachea and lungs will naturally flow to the trachea under pressure, and each impact will produce 450 to 500 ml of gas, which may discharge foreign bodies and restore airway patency.
If there is no one around during the acute respiratory tract foreign body obstruction, the patient can also impact the abdomen by himself in the same way, or press the upper abdomen on any hard and protruding object and repeat it.
