Generally speaking, for foreign body airway obstruction, the most commonly used method is the Heimlich maneuver.
The principle is to use an impact on the abdominal area, beneath the diaphragm's soft tissues. The sudden impact creates an upward pressure, compressing the lower part of the lungs to drive the remaining air to form a flow. This impactful and directional airflow can dislodge the object blocking the throat and save the person's life.
However, the Heimlich maneuver also has a high risk of complications and is not very effective.
The little girl's father was clearly not proficient in this operation.
By the time she was brought to the hospital, the little girl had already lost consciousness; at such a critical juncture, the Heimlich maneuver is not the most effective measure.
In the hospital, the choice of bronchoscopy and tracheotomy is much more appropriate than the Heimlich maneuver.
