OBJECTIVE The purpose of the study was to determine whether applying highly recommended changes in the 2005 American Heart Association (AHA) Guidelines would improve outcomes after out-of-hospital cardiac arrest. BACKGROUND In 2005, AHA recommended multiple ways to improve circulation during cardiopulmonary resuscitation (CPR). METHODS Conglomerate(More)
OBJECTIVE The purpose of this study is to: 1) describe a newly mechanism of blood flow to the brain during cardiopulmonary resuscitation using the impedance threshold device in a piglet model of cardiac arrest, and 2) describe the survival benefits in humans of applying all of the highly recommended changes in the 2005 guidelines related to increasing(More)
BACKGROUND The respiratory pump can be optimized to enhance circulation in patients with hypotension by having patients spontaneously breathe through a low level of inspiratory resistance. This can be achieved with an impedance threshold device (ITD) designed to provide 7 cm H2O resistance during spontaneous inspiration with minimal resistance during(More)
The paper presents data on the effect of 5-fluorouracil (5-FU)-impregnated Coletex napkins on rats and mice with transplantable subcutaneous tumors of different histological patterns: Pliss lymphosarcoma, Walker carcinosarcoma and Ehrlich carcinoma. Since the napkins showed antitumor activity it is suggested that they might find application in treating a(More)
