There are three main steps to using the Heimlich maneuver when stuck. 1. The rescuer stands behind the patient, puts the right foot into the middle of the patient’s legs, in a bow-step position, and at the same time gently pushes the patient’s back with his hand to tilt his upper body forward, so that the patient’s head is lowered and his mouth is opened, which is more helpful for the exclusion of foreign bodies from the airway. 2. The rescuer turns the right hand into a clenched fist, and uses the thumb and forefinger to stick to the stomach between the patient’s xiphoid process and navel at the same time, which is equivalent to sticking to the part of the navel above the distance of two horizontal fingers. 3. Finally, put the left hand on the right fist and hold it tightly, both hands quickly, vigorously and repeatedly to the inner upper impact on the abdomen, 5 times as a group, each time the action needs to be clearly separated. Specific practices and precautions, you can consult a medical professional advice.
