Randomized Controlled Trial
A new defibrillator mode to reduce chest compression interruptions for health care professionals and lay rescuers: a pilot study in manikins.
Chest compression interruptions are detrimental during the resuscitation of cardiac arrest patients, especially immediately prior to shock delivery. ⋯ Preshock pause time is reduced by 80% utilizing a novel technology that employs automated analysis and charging during chest compression. Although chest compression pause time is reduced with the use of the new technology, participants do not excessively fatigue.

Randomized Controlled Trial
Direct versus video laryngoscopic intubation by novice prehospital intubators with and without chest compressions: A pilot manikin study.
To evaluate whether chest compressions affect the time taken for intubation (TTI) using the Macintosh laryngoscope and two portable video laryngoscopes (VLs) (GlideScope Ranger and Airway Scope) when used by novice prehospital caregivers, and to compare the TTIs and rates of successful intubation among the three laryngoscopes with and without chest compressions in a manikin model. ⋯ In this pilot study, chest compressions did not significantly affect the TTI using the Macintosh laryngoscope and two portable VLs when used by novice prehospital caregivers in the manikin model on the floor. Considering the fairly short training time, two portable VLs may be potentially useful adjuncts for tracheal intubation during chest compressions for novice prehospital caregivers. Further studies are required to validate whether these findings are clinically relevant.

Randomized Controlled Trial
Comparison of bougie-assisted intubation with traditional endotracheal intubation in a simulated difficult airway.
To compare the success and ease of bougie-assisted intubation (BAI) with those of traditional endotracheal intubation (ETI) in a simulated difficult airway (20.4 seconds for BAI vs. 16.7 seconds for ETI, p = 0.102). ⋯ In a simulated difficult airway, BAI has a higher success rate than traditional ETI without increasing the time to successful intubation. Intubators perceive BAI as being easier to perform than traditional ETI in this simulated difficult airway scenario.

Randomized Controlled Trial
Intraosseous devices: a randomized controlled trial comparing three intraosseous devices.
Access to the circulation is mandatory for adequate treatment in medical emergency situations. Intraosseous (IO) infusion is a safe, fast, and effective alternative for gaining access to the circulation, if intravenous access fails. In the last decade, the IO method gained renewed interest. New devices have been developed, such as the Bone Injection Gun (BIG) 15G/18G and the First Access for Shock and Trauma 1 (FAST1). ⋯ The Jamshidi 15G needle could be placed significantly faster than the FAST1. The devices had similar success rates, complication rates, and user-friendliness. Intraosseous devices provide a safe, simple, and fast method for gaining access to the circulation in emergency situations.

Randomized Controlled Trial Comparative Study
The King LT versus the Combitube: flight crew performance and preference.
Air medical personnel frequently face the challenge of the emergency airway. The Combitube is an airway device commonly used by emergency medical services (EMS) providers as either a primary or rescue airway. ⋯ The King LT was placed significantly faster than the Combitube and was also perceived as easier to place. Ninety-six percent of the participants preferred the King LT. Limitations include using a simulator model rather than a human model.
