High quality cardiopulmonary resuscitation (CPR) in the pre-hospital setting has been associated with improved survival rates during cardiopulmonary arrest (CPA). Recent documentation of hyperventilation associated deterioration in hemodynamics during CPR, suggests that guided or controlled ventilation strategies may contribute to improved hemodynamics and increased survival. ⋯ The use of improved thoracic impedance pneumography and capnography are appealing for such monitoring because of the widespread availability, but modifications to existing software and clinical data compared to a clinical standard would be required before general acceptance is possible. Other methods listed may offer advantages over these in select circumstances.

Randomized Controlled Trial Comparative Study
Airway management by paramedics using endotracheal intubation with a laryngoscope versus the oesophageal tracheal Combitube and EasyTube on manikins: a randomised experimental trial.
The EasyTube, which is constructed in a similar way to the Combitube, is a recently introduced alternative to tracheal intubation for airway management in emergency medicine. ⋯ For paramedics tested on manikins placement success rate was higher with less time required for the Combitube and Easytube than for tracheal intubation with no differences between the Combitube and EasyTube.

Randomized Controlled Trial Comparative Study
One-handed versus two-handed chest compressions in paediatric cardio-pulmonary resuscitation.
To determine emergency department (ED) staff preference for one- or two-handed paediatric chest compressions and to determine if there was a difference in compression rates delivered and fatigability between the techniques. ⋯ This study showed that CPR compression rate is similar with one- and two-handed compression techniques, but compression rate decreased more quickly with the one-handed technique. The majority of staff preferred the two-handed compression technique for reasons of ease, control and uniformity with other CPR techniques.

Comparative Study
Clinical consequences of the introduction of mechanical chest compression in the EMS system for treatment of out-of-hospital cardiac arrest-a pilot study.
To evaluate the outcome among patients suffering from out-of-hospital cardiac arrest (OHCA) after the introduction of mechanical chest compression (MCC) compared with standard cardiopulmonary resuscitation (SCPR) in two emergency medical service (EMS) systems. ⋯ In this pilot study, the results did not support the hypothesis that the introduction of mechanical chest compression in OHCA improves outcome. However, there is room for further improvement in the use of the device. The hypothesis that this will improve outcome needs to be tested in further prospective trials.

The Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care recommend that for adult cardiac arrest the single rescuer performs "two quick breaths followed by 15 chest compressions." This cycle is continued until additional help arrives. Previous studies have shown that lay persons and medical students take 16 +/- 1 and 14 +/- 1 s, respectively, to perform these "two quick breaths." The purpose of this study was to determine the time required for trained professional paramedic firefighters to deliver these two breaths and the effects that any increase in the time it takes to perform rescue breathing would have on the number of chest compressions delivered during single rescuer BLS CPR. We hypothesized that trained professional rescuers would also take substantially longer then the Guidelines recommendation for delivering the two rescue breaths before every 15 compressions during simulated single rescuer BLS CPR. ⋯ Trained professional emergency rescue workers perform rescue breathing somewhat faster than lay rescuers or medical students, but still require two and one half times longer than recommended. The time required to perform these breaths significantly decreases the number of chest compressions delivered per minute. This may affect outcome as experimental studies have shown that more than 80 compressions delivered per minute are necessary for survival from prolonged cardiac arrest.
