美国密执安迪尔伯恩消息:由于常规的无除颤(功能)的心肺复苏(CPR)效果不佳,其住院和未住院患者的总存活率等于或低于5％,所以研究人员正在研制替代技术。巴尔的摩市医院冠心病监护病房主任、约翰斯·霍布金斯医学院医学副教授Nisha Chandra医师在密执安举行的美国急救医师学院年会上所做的重点发言中提出此警告。发展复苏新技术的关键之一是要了解CPR时的血流机理。Chandra引证了两种可能血流机理:一种是由于改变胸内压,另一种是对心脏或心室直接加压。她说后一种机理很少发生作用,但若一出现,就会有效地使血液流入局
Dearborn, MI, USA News: Researchers are working on a 5% or better overall and non-hospitalized overall survival rate due to poor routine defibrillation (functional) cardiopulmonary resuscitation (CPR) Development of alternative technologies. Dr Nisha Chandra, MD, director of the Coronary Care Unit at Baltimore City Hospital and an associate professor of medicine at Johns Hopkins Medical School, presented this warning in a keynote address at the annual meeting of the American College of Emergency Physicians in Michigan. One of the keys to developing new technologies for recovery is understanding the blood flow mechanism at CPR. Chandra cites two possible mechanisms of blood flow: one is due to changes in intrathoracic pressure and the other is direct compression of the heart or ventricle. She said that the latter mechanism seldom had any effect, but if it did, it would effectively flow blood in
