Randomized Controlled Trial Comparative Study
Out-of hospital advanced life support with or without a physician: effects on quality of CPR and outcome.
The presence of physicians is believed to facilitate optimal management of out-of-hospital cardiac arrest, but has not been sufficiently documented. ⋯ Survival after out-of-hospital cardiac arrest was not different for patients treated by the PMA and non-PMA in our EMS system.

"Mouth to mouth ventilation": a comparison of the laryngeal mask airway with the Laerdal Pocket Facemask.
Ten nurses with basic airway management experience were formally trained to use a classic laryngeal mask airway (LMA) and a Laerdal Pocket Facemask (LPFM) for oxygen enriched expired air ventilation (EEAV). They then used both of these devices for EEAV in a randomised fashion in 100 anaesthetised ASA I/II patients for elective surgery. EEAV was considered successful if the patient's arterial oxygen saturation was maintained above 93% on room air for 3 min. ⋯ There was no apparent learning curve for either apparatus. Mean time in seconds (s) for first successful ventilation from picking up the apparatus was 26.8s and 15.1s, for the LMA and LPFM respectively (P<0.005). Although the LMA took significantly longer time to insert, it proved to be more successful and easier to use than the LPFM for EEAV.

Effects of AED device features on performance by untrained laypersons.
Our study evaluates the impact of features of automated external defibrillators (AEDs) on the performance and speed of untrained laypersons to deliver a shock and initiate CPR after a shock. ⋯ Most untrained laypersons were successful in delivering a shock. Device features had the most impact on these functions: ability and time to power-on device, adequacy of pad position and initiation of CPR.
