Applying subdiaphragmatic compression has been successful in saving victims of food-choking and drowning by expelling the asphyxiating bolus or aspirated water. Sudden elevation of the diaphragm compresses the lungs, which explosively forces air out through the trachea, ejecting the obstructing object. The flow rate, pressure, and volume of air expelled were determined in 10 subjects and found to be substantial, providing confirmation of the effectiveness of the procedure.
应用膈下按压法已成功挽救了食物窒息和溺水的受害者，通过排出窒息性食团或吸入的水。膈肌突然抬高会压缩肺部，从而爆炸性地迫使空气通过气管排出，将阻塞物喷出。对10名受试者排出的气流速率、压力和空气量进行了测定，结果发现这些数值相当可观，证实了该操作的有效性。
