Resuscitation after prolonged ventricular fibrillation with use of monophasic and biphasic waveform pulses for external defibrillation.
BACKGROUND Survival after prolonged ventricular fibrillation (VF) appears severely limited by 2 major factors: (1) low defibrillation success rates and (2) persistent post-countershock myocardial dysfunction. Biphasic (BP) waveforms may prove capable of favorably modifying these limitations. However, they have not been rigorously tested against monophasic (MP) waveforms in clinical models of ex...
متن کاملA comparison of biphasic and monophasic waveform defibrillation after prolonged ventricular fibrillation.
STUDY OBJECTIVE To compare the effects of biphasic defibrillation waveforms and conventional monophasic defibrillation waveforms on the success of initial defibrillation, postresuscitation myocardial function, and duration of survival after prolonged duration of untreated ventricular fibrillation (VF), including the effects of epinephrine. DESIGN Prospective, randomized, animal study. SETTI...
متن کاملImmediate defibrillation or defibrillation after cardiopulmonary resuscitation.
OBJECTIVES This study aimed to determine whether short cardiopulmonary resuscitation (CPR) by emergency medical services before defibrillation (CPR first) has a better outcome than immediate defibrillation followed by CPR (shock first) in patients with ventricular fibrillation/pulseless ventricular tachycardia (VF/pulseless VT) out-of-hospital cardiac arrest. METHODS We analyzed a national da...
متن کاملOptimizing the timing of defibrillation: the role of ventricular fibrillation waveform analysis during cardiopulmonary resuscitation.
Despite important advances in prevention, cardiac arrest (CA) is still a leading cause of death in many parts of the world. The principles of cardiopulmonary resuscitation (CPR) have remained fundamentally unchanged during the past 40 years. Successful resuscitation is strongly associated with several specific interventions, including early bystander CPR, earlier defibrillation, high quality of...

abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
