The original intention of Cardiopulmonary Resuscitation (CPR) mechanical equipment is to increase the blood flow in the heart and brain of patients with cardiac arrest, and to serve as a bridge for subsequent defibrillation, intravenous medication, and revascularization.
Regrettably, the traditional freehand CPR has very little blood flow to the heart and brain, so even though CPR has been a standard CPR for 50 years, most patients with cardiac arrest still end in death. Studies have shown that freehand CPR can only provide 10% to 20% of blood flow to the heart under normal physiological conditions, and 20% to 30% of blood flow to the brain.
The medical community's urgent need for high-quality CPR technology, coupled with the inherent limitations of traditional free-handed CPR, has spurred a new wave of new technologies that can increase circulating blood volume. The development of mechanical equipment for cardiopulmonary resuscitation has also gone through a certain course.
Of course, whether it is a free-handed CPR or a mechanical CPR (cardiopulmonary resuscitation machine), the ultimate goal is to improve the perfusion blood flow in the heart and brain of patients with cardiac arrest, avoid the heart and brain from entering an irreversible state of death, and gradually repair the heart and brain. Organs work function.
Mechanical CPR, which uses cardiopulmonary resuscitation machinery for CPR, is commonly referred to as cardiopulmonary resuscitation, cardiopulmonary resuscitation, and cardiopulmonary resuscitation.
