摘要： Context: The survival benefit of well-performed cardiopulmonary resuscitation(CPR) is well-documented, but little objective data exist regarding actual CPR quality during cardiac arrest. Recent studies have challenged the notion that CPR is uniformly performed according to established international guidelines. Objectives: To measure multiple parameters of in-hospital CPR quality and to determine compliance with published American Heart Association and international guidelines. Design and Setting: A prospective observational study of 67 patients who experienced in-hospital cardiac arrest at the University of Chicago Hospitals, Chicago, Ill, between December 11, 2002, and April 5, 2004. Using a monitor/-defibrillator with novel additional sensing capabilities, the parameters of CPR quality including chest compression rate, compression depth, ventilation rate, and the fraction of arrest time without chest compressions(no-flow fraction) were recorded. Main Outcome Measure: Adherence to American Heart Association and international CPR guidelines. Results: Analysis of the first 5 minutes of each resuscitation by 30-second segments revealed that chest compression rates were less than 90/min in 28.1%of segments. Compression depth was too shallow(defined as< 38 mm) for 37.4%of compressions. Ventilation rates were high, with 60.9%of segments containing a rate of more than 20/min. Additionally, the mean(SD) no-flow fraction was 0.24(0.18). A 10-second pause each minute of arrest would yield a no-flow fraction of 0.17. A total of 27 patients(40.3%) achieved return of spontaneous circulation and 7(10.4%) were discharged from the hospital. Conclusions: In this study of in-hospital cardiac arrest, the quality of multiple parameters of CPR was inconsistent and often did not meet published guideline recommendations, even when performed by well-trained hospital staff. The importance of high-quality CPR suggests the need for rescuer feedback and monitoring of CPR quality during resusc

摘要： Context: Cardiopulmonary resuscitation(CPR) guidelines recommend target values for compressions, ventilations, and CPR-free intervals allowed for rhythm analysis and defibrillation. There is little information on adherence to these guidelines during advanced cardiac life support in the field. Objective: To measure the quality of out-of-hospital CPR performed by ambulance personnel, as measured by adherence to CPR guidelines. Design and Setting: Case series of 176 adult patients with out-of-hospital cardiac arrest treated by paramedics and nurse anesthetists in Stockholm, Sweden, London, England, and Akershus, Norway, between March 2002 and October 2003. The defibrillators recorded chest compressions via a sternal pad fitted with an accelerometer and ventilations by changes in thoracic impedance between the defibrillator pads, in addition to standard event and electrocardiographic recordings. Main Outcome Measure: Adherence to international guidelines for CPR. Results: Chest compressions were not given 48%(95%CI, 45%-51%) of the time without spontaneous circulation; this percentage was 38%(95%CI, 36%-41%) when subtracting the time necessary for electrocardiographic analysis and defibrillation. Combining these data with a mean compression rate of 121/min(95%CI, 118-124/min) when compressions were given resulted in a mean compression rate of 64/min(95%CI, 61-67/min). Mean compression depth was 34mm(95%CI, 33-35 mm), 28%(95%CI, 24%-32%) of the compressions had a depth of 38 mm to 51 mm(guidelines recommendation), and the compression part of the duty cycle was 42%(95%CI, 41%-42%). A mean of 11(95%CI, 11-12) ventilations were given per minute. Sixty-one patients(35%) had return of spontaneous circulation, and 5 of 6 patients discharged alive from the hospital had normal neurological outcomes. Conclusions: In this study of CPR during outof-hospital cardiac arrest, chest compressions were not delivered half of the time, and most compressions were too shallow. Electrocardiog
