Abstract:

 Cardiopulmonary Resuscitation CPR, a method of medical intervention for Cardiac Arrest, requires effective chest compressions that energize blood to flow to vital organs. The recommended technique for CPR according to the American Heart Association AHA guidelines is standard manual CPR. However, in recent years, many different mechanical CPR technologies have been improved to achieve more consistent chest compression. Although these technologies can achieve manual CPR parameters described in AHA guidelines, none have been proven to be superior to manual CPR. A potential explanation of how machines cannot be superior to humans is initial momentum. The human upper body mass can be a good source of momentum during manual CPR, and chest compression with high initial momentum and hence with high acceleration can enable blood to flow in a pulsatile waveform. In this study, a novel mechanical CPR device with a special piston mechanism capable of high acceleration chest compression consisting of a double slider-crank and dynamic conrod is designed. The position and velocity-time graphs of the simulation results of the designed piston mechanism are compared with both mathematical modelling and the results of LUCAS-2 and CORPULS devices obtained from another study, and it is confirmed that the proposed mechanism has higher acceleration.

 Kalp durması için bir tıbbi müdahale yöntemi olan KardiyoPulmoner Resusitasyon KPR, kanın hayati organlara akması için enerji veren etkili göğüs kompresyonları gerektirir. Amerikan Kalp Derneği AHA yönergelerine göre önerilen KPR tekniği standart manuel KPRdir. Ancak son yıllarda, daha tutarlı göğüs kompresyonu elde etmek için birçok farklı mekanik KPR teknolojisi geliştirilmiştir. Bu teknolojiler, AHA kılavuzlarında belirtilen manuel KPR parametrelerine ulaşabilseler de, hiçbirinin manuel KPRden daha üstün olduğu henüz kanıtlanmamıştır. Makinelerin insanlardan nasıl daha üstün olamayacağının olası bir açıklaması başlangıç momentumudur. İnsan üst vücut kütlesi, manuel KPR sırasında iyi bir momentum kaynağı olabilir ve yüksek başlangıç momentumlu ve dolayısıyla yüksek ivmeli göğüs kompresyonu, kanın pulsatil bir dalga biçiminde akmasını sağlayabilir. Bu çalışmada, çift kaydırıcı-krank ve dinamik biyelden oluşan yüksek ivmeli göğüs kompresyonu yapabilen özel piston mekanizmalı yeni bir mekanik KPR cihazı tasarlanmıştır. Tasarlanan piston mekanizmasının simülasyon sonuçlarının konum ve hız-zaman grafikleri hem matematiksel model hem de başka bir çalışmadan elde edilen LUCAS-2 ve CORPULS cihazlarının sonuçları ile karşılaştırılmış ve önerilen mekanizmanın daha yüksek ivmeye sahip olduğu doğrulanmıştır.
