Randomized Controlled Trial Comparative Study
Comparison of air-Q(®) and Soft Seal(®) laryngeal mask for airway management by novice doctors during infant chest compression: a manikin study.
Recent resuscitation guidelines for infant cardiopulmonary resuscitation (CPR) emphasise that rescuers should minimise the interruption of chest compressions. To that end, supraglottic devices such as laryngeal mask airways (LMAs) are suggested as a backup for airway management during infant CPR. We therefore compared the utility of the air-Q(®) LMA (air-Q) with that of the Soft Seal(®) LMA (Soft Seal) for infant CPR in an infant manikin. ⋯ We conclude that novice doctors find the air-Q easier to use than Soft Seal for emergency airway management during chest compression in infants, in an infant manikin.

Randomized Controlled Trial
The impact of chest compression rates on quality of chest compressions - a manikin study.
Chest compressions are often performed at a variable rate during cardiopulmonary resuscitation (CPR). The effect of compression rate on other chest compression quality variables (compression depth, duty-cycle, leaning, performance decay over time) is unknown. This randomised controlled cross-over manikin study examined the effect of different compression rates on the other chest compression quality variables. ⋯ For Guidelines 2005 trained rescuers, a chest compression rate of 100-120 min(-1) for 2 min is feasible whilst maintaining adequate chest compression quality in terms of depth, duty-cycle, leaning, and decay in compression performance. Further studies are needed to assess the impact of the Guidelines 2010 recommendation for deeper and faster chest compressions.

Randomized Controlled Trial
A different rescuer changing strategy between 30:2 cardiopulmonary resuscitation and hands-only cardiopulmonary resuscitation that considers rescuer factors: a randomised cross-over simulation study with a time-dependent analysis.
To compare the time-dependent changes in the quality of chest compressions in 30:2 cardiopulmonary resuscitation (CPR) and hands-only cardiopulmonary resuscitation (HO-CPR) and to evaluate how individual rescuer factors affect the quality of chest compressions over time for both CPR techniques. ⋯ Switching rescuers at an interval of 2-min is reasonable for 30:2 CPR. However, for HO-CPR switching rescuers every 1-min may be preferable except when rescuers are male or obese/overweight (BMI≥25).
