Simultaneous beat-to-beat assessment of arterial blood pressure and quality of cardiopulmonary resuscitation in out-of-hospital and in-hospital settings.

Objective: The current recommendation for depth and rate of chest compression (CC) during cardiopulmonary resuscitation (CPR) is based on limited hemodynamic data recorded during human CPR. We have evaluated the possible association between CC depth and rate and continuously measured arterial blood pressure during adult CPR.

Methods: This prospective study included data from 104 patients resuscitated inside or outside hospital.

Effect of mattress and bed frame deflection on real chest compression depth measured with two CPR sensors.

Aim: Implementation of chest compression (CC) feedback devices with a single force and deflection sensor (FDS) may improve the quality of CPR. However, CC depth may be overestimated if the patient is on a compliant surface. We have measured the true CC depth during in-hospital CPR using two FDSs on different bed and mattress types.

Association of arterial blood pressure and CPR quality in a child using three different compression techniques, a case report.

Unlabelled: A 2-year-old boy found in cardiac arrest secondary to drowning received standard CPR for 35 minutes and was transported to a tertiary hospital for rewarming from hypothermia. Chest compressions in hospital were started using two-thumb encircling hands technique. Subsequently two-thumbs direct sternal compression technique and after sternal force/depth sensor placement, chest compression with classic one-hand technique were done.

Real-time audiovisual feedback system in a physician-staffed helicopter emergency medical service in Finland: the quality results and barriers to implementation.

Objectives: To evaluate the quality of cardiopulmonary resuscitation (CPR) in a physician staffed helicopter emergency medical service (HEMS) using a monitor-defibrillator with a quality analysis feature. As a post hoc analysis, the potential barriers to implementation were surveyed.

Methods: The quality of CPR performed by the HEMS from November 2008 to April 2010 was analysed.

Deeper chest compression - more complications for cardiac arrest patients?

Aim Of The Study: Sternal and rib fractures are frequent complications caused by chest compressions during cardiopulmonary resuscitation (CPR). This study aimed to investigate the potential association of CPR-related thoracic and abdominal injuries and compression depth measured with an accelerometer.

Methods: We analysed the autopsy records, CT scans or chest radiographs of 170 adult patients, suffering in-hospital cardiac arrest at the Tampere University Hospital during the period 2009-2011 to investigate possible association of chest compressions and iatrogenic injuries.

Quality controlled manual chest compressions and cerebral oxygenation during in-hospital cardiac arrest.

Aim: The quality of cardiopulmonary resuscitation (CPR) is associated with the rate of return of spontaneous circulation (ROSC) during human cardiac arrest. Current advances in defibrillator technology enable measurement of CPR quality during resuscitation, but it is not known whether this is directly reflected in cerebral oxygenation. In this descriptive study we aimed to evaluate whether the quality of feedback-monitored CPR during in-hospital cardiac arrest is reflected in near infrared frontal cerebral spectroscopy (NIRS).

Blood pressure during resuscitation in man--the effect of pause during rhythm analysis revisited.

Aims: This study reports invasive arterial pressures before and after the rhythm analysing pauses during CPR and evaluates the possible association of the quality of CPR and the length of the pause with blood pressure around the pause.

Materials And Methods: Five patients who experienced out-of hospital or in-hospital cardiac arrest were included in the study. Using a monitor/defibrillator with sensing capabilities, the parameters of CPR quality including chest compression depth, rate, force and the duration of interruption were recorded and compared to blood pressure.
