X-Message-Number: 2408 From: Ralph Merkle <> Subject: CRYONICS: Pneumatic Vests and Cardiopulmonary Resuscitation Date: Wed, 15 Sep 1993 17:58:17 PDT The Sept 9, 1993 issue of the New England Journal of Medicine, page 762-768, Vol. 329 No. 11, has an article titled: A Preliminary Study of Cardiopulmonary Resuscitation by Circumferential Compression of the Chest with Use of a Pneumatic Vest, by Halperin et. al. Some quotes from the abstract: "Methods: to produce periodic increases in intrathoracic pressure, we developed a pneumatically cycled circumferential thoracic vest system and compared the results of the use of this system in CPR (vest CPR) with those of manual CPR." "Results: In phase 1 of the study, vest CPR increased the peak aortic pressure from 78 +/- 26 mm Hg to 138 +/- 28 mm Hg (P<0.001) and the coronary perfusion pressure from 15 +/- 8 mm Hg to 23 +/- 11 mm Hg (P<0.003)." "Conclusions: In this preliminary study, vest CPR, despite its late application, successfully increased aortic pressure and coronary perfusion pressure, and there was an insignificant trend toward a greater likelihood of the return of spontaneous circulation with vest CPR than with continued manual CPR. The effect of vest CPR on survival, however, is currently unknown and will require further study." Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=2408
