x Filtering the cardiopulmonary resuscitation (CPR) artifact has been a major approach to minimizing interruptions to CPR for rhythm analysis. However, the effects of these filters on interruptions to CPR have not been evaluated. This study presents the first methodology for directly quantifying the effects of filtering on the uninterrupted CPR time.

x Hemothorax is not an uncommon cardiopulmonary resuscitation (CPR)–related complication. But hemothorax related to azygos vein injury (AVI) is a rare condition following blunt chest trauma, with no report of CPR-related AVI in the literature. We present a case of azygos vein rupture in a middle-aged woman after repeated chest compression during 1 hour of CPR. She eventually presented with massive hemothorax due to azygos vein rupture diagnosed by computed tomography (CT). When faced with a patient with massive hemothorax after chest compression, azygos vein rupture should be considered as a complication.

They use needle guides during ultrasound-guided central venous catheterization (CVC) with and without chest compressions on manikin. Catheterization was performed by anesthesiologists stuff.

x Metronome guidance is a simple and economical feedback system for guiding cardiopulmonary resuscitation (CPR). However, a recent study showed that metronome guidance reduced the depth of chest compression. The results of previous studies suggest that a higher chest compression rate is associated with a better CPR outcome as compared with a lower chest compression rate, irrespective of metronome use. Based on this finding, we hypothesized that a lower chest compression rate promotes a reduction in chest compression depth in the recent study rather than metronome use itself.

x The question of whether the placement of the dominant hand against the sternum could improve the quality of manual chest compressions remains controversial. In the present study, we evaluated the influence of dominant vs nondominant hand positioning on the quality of conventional cardiopulmonary resuscitation (CPR) during prolonged basic life support (BLS) by rescuers who performed optimal and suboptimal compressions.

x Three currently available mechanical devices for cardiopulmonary resuscitation (CPR) were compared using a canine cardiac arrest model. Twenty-four-hour survival without neurologic deficit was the goal. A group of 30 large mongrel dogs was divided equally among Thumper® CPR, simultaneous compression and ventilation (SCV) CPR, and vest CPR. Ventricular fibrillation was induced electrically, and after 3 minutes of no intervention, one of the three types of mechanical CPR was performed for 17 minutes.
The need for head rotation and abdominal compressions during bystander cardiopulmonary resuscitation Eric M. Rottenberg

x The current AHA-ECC guidelines for basic life support focus on the provision of good chest compressions with minimal interruptions for patients with presumed out-of-hospital cardiac arrest. Moreover, international consensus guidelines now support the use of chest compression-only cardiopulmonary resuscitation (CPR) instructions for dispatcher-assisted CPR given over the phone to untrained bystanders. However, evidence that strongly challenge these recommendations have been overlooked. A review of this evidence argues for the need for head rotation (a hands-free method of airway control) and abdominal compressions during bystander CPR.

x Gastric rupture is a rare complication after cardiopulmonary resuscitation (CPR). In most cases, incorrect management of airways during CPR is the main cause. Therefore, a medical emergency becomes a surgical emergency also. We present a case of gastric perforation in a middle-aged patient after CPR performed by his family. He eventually presented with bloody vomitus and a tympanic abdomen. When faced with a patient with abdominal signs post-CPR, surgical complications of CPR should be considered.

x The addition of abdominal counterpulsation to standard cardiopulmonary resuscitation (AC-CPR) during ventricular fibrillation has been shown to improve cardiac output, oxygen uptake, and central arterial blood pressure in dogs. The present study was performed to determine the effect of AC-CPR on regional blood flow. Regional blood flow was measured with radioactively labeled microspheres during sinus rhythm and during alternate periods of AC-CPR and standard CPR (STD-CPR) in nine dogs anesthetized with pentobarbital.

x High-quality chest compressions (CCs) are an important component of successful resuscitation. Suboptimal in-hospital CC are commonly reported. Skill degradation and fatigue have been implicated. We assessed the effect of a handheld feedback device on the measured and perceived quality of CC and rescuer physiologic response.

x Cardiopulmonary resuscitation (CPR) is highlighted frequently on television, portraying unrealistically high success rates. Multiple surveys have also revealed unrealistically high expectations of success. Jones et al [1] found expectations to be as high as 75% among the American public and attributed this to the use of television as a source of information. Roberts et al [2], in a study of attending physicians and nurses, found predictions of 24% and 30% survival for adult CPRs, respectively. Overall survival rates to hospital discharge, however, average less than 16% both for out-of-hospital and inhospital arrests [3-9].

x We read with great interest the article by Geddes et al. concerning a new CPR (cardiopulmonary resuscitation) method using OAC (only rhythmic abdominal compression). However, we note several issues. First, the authors tried investigating how to maintain coronary perfusion when CPA (cardiopulmonary arrest) with ventricular fibrillation had occurred. But the most important objective of CPR is not to maintain coronary perfusion, but it is to protect the brain from the hypoxia so that patients would gain favorable neurological outcome [1,2].
