Comparative Study
Efficacy and safety of the EZ-IO™ intraosseous device: Out-of-hospital implementation of a management algorithm for difficult vascular access.
Intraosseous access is a rapid and safe alternative when peripheral vascular access is difficult. Our aim was to assess the safety and efficacy of a semi-automatic intraosseous infusion device (EZ-IO) when using a management algorithm for difficult vascular access in an out-of-hospital setting. ⋯ On implementation of an algorithm for the management of difficult vascular access, the EZ-IO device proved safe and highly effective in both adult and paediatric patients in an out-of-hospital emergency setting. It is a suitable device for consideration as a first-line option for difficult vascular access in this setting.

Randomized Controlled Trial Comparative Study
Performer fatigue and CPR quality comparing 30:2 to 15:2 compression to ventilation ratios in older bystanders: A randomized crossover trial.
We sought to compare bystander fatigue and CPR quality after 5min of CPR using the 30:2 vs. the 15:2 chest compression:ventilation ratios in a population of older participants. ⋯ In this study of older volunteers, the 30:2 CPR ratio resulted in similar objective measures of fatigue, but higher perceived fatigue than the 15:2 ratio. The 30:2 ratio resulted in proportionally more inadequate compressions.

Comparative Study
Time-dependent effectiveness of chest compression-only and conventional cardiopulmonary resuscitation for out-of-hospital cardiac arrest of cardiac origin.
Little is known about the effect of the type of bystander-initiated cardiopulmonary resuscitation (CPR) for prolonged out-of-hospital cardiac arrest (OHCA). ⋯ For prolonged OHCA of cardiac origin, conventional CPR with rescue breathing provided incremental benefit compared with either no CPR or compression-only CPR, but the absolute survival was low regardless of type of CPR.
