CONTEXT Chest compression-only bystander cardiopulmonary resuscitation (CPR) may be as effective as conventional CPR with rescue breathing for out-of-hospital cardiac arrest. OBJECTIVE To investigate the survival of patients with out-of-hospital cardiac arrest using compression-only CPR (COCPR) compared with conventional CPR. DESIGN, SETTING, AND(More)
The effect of the duration of inadequate coronary perfusion pressure on resuscitation from cardiac arrest was examined in 32 mongrel dogs with a mean weight of 22 +/- 5 kg. In all dogs, the heart was electrically fibrillated and closed chest compression with assisted ventilation was performed for 15 minutes. At this time, all dogs had an inadequate coronary(More)
BACKGROUND Bystander cardiopulmonary resuscitation (CPR) decreases mortality from out-of-hospital cardiac arrest significantly. Accordingly, layperson CPR is an integral component in the chain of survival for out-of-hospital cardiac arrest victims. The near statewide incidence and location of layperson CPR is unknown. OBJECTIVE To determine true incidence(More)
CONTEXT Out-of-hospital cardiac arrest is a major public health problem. OBJECTIVE To investigate whether the survival of patients with out-of-hospital cardiac arrest would improve with minimally interrupted cardiac resuscitation (MICR), an alternate emergency medical services (EMS) protocol. DESIGN, SETTING, AND PATIENTS A prospective study of(More)
BACKGROUND The incidence and significance of gasping after cardiac arrest in humans are controversial. METHODS AND RESULTS Two approaches were used. The first was a retrospective analysis of consecutive confirmed out-of-hospital cardiac arrests from the Phoenix Fire Department Regional Dispatch Center text files to determine the presence of gasping soon(More)
BACKGROUND Bystander cardiopulmonary resuscitation (CPR) is performed on only a small percentage of patients who suffer cardiac arrest. We conducted a study to elucidate attitudes toward and potential obstacles to performance of bystander CPR. METHODS Attitude survey of 975 people on the University Heart Center, University of Arizona, Tucson, mailing(More)
The objective of this study was to examine the use of limited, goal-directed, two-dimensional ultrasound studies performed by emergency physicians and to assess the frequency, variety, and accuracy of their readings. A 1-year prospective study was performed by using an emergency department (ED) ultrasound machine with a 3.5-mHz mechanical oscillating sector(More)
In response to public pressure for greater accountability from the medical profession, a transformation is occurring in the approach to medical education and assessment of physician competency. Over the past 5 years, the Accreditation Council for Graduate Medical Education (ACGME) has implemented the Outcomes and General Competencies projects to better(More)
BACKGROUND Despite improving arterial oxygen saturation and pH, bystander cardiopulmonary resuscitation (CPR) with chest compressions plus rescue breathing (CC+RB) has not improved survival from ventricular fibrillation (VF) compared with chest compressions alone (CC) in numerous animal models and 2 clinical investigations. METHODS AND RESULTS After 3(More)
We performed a study to determine if the measurement of expired PCO2 during CPR for cardiac arrest could be used as a prognostic indicator of successful resuscitation. Twelve mongrel dogs were fibrillated electrically, and external chest massage and assisted ventilation were applied for 15 minutes. Expired PCO2 and aortic and right atrial pressures were(More)
