Cardiopulmonary resuscitation is the delivery of blood to organs throughout the body through chest compressions, chest rise and fall, and pressure changes in the chest cavity. While clothing restraints increase the pressure on the heart and may limit chest rise and fall, undressing is required when performing CPR on women.
Undressing makes it easier for the operator to more accurately position the compressions. The correct position for CPR compressions is in the middle to lower third of the sternum. When clothing is covered, this may result in a deviation in position, which may lead to rib fractures, pneumothorax, rupture of the spleen, and other possibilities when compressions are applied.
Undoing the clothing can facilitate the operation of CPR. Cardiopulmonary resuscitation has strict requirements for the depth, strength, and frequency of compressions, and when covered by clothing, it affects the operator’s intuitive judgment, leading to deviations in the depth and frequency of compressions, resulting in ineffective compressions.
CPR is a first aid measure, very practical in daily life, and it is recommended that the operator should be trained as much as possible before performing the operation.
