Observational Study
The association between AHA CPR quality guideline compliance and clinical outcomes from out-of-hospital cardiac arrest.
Measures of chest compression fraction (CCF), compression rate, compression depth and pre-shock pause have all been independently associated with improved outcomes from out-of-hospital (OHCA) cardiac arrest. However, it is unknown whether compliance with American Heart Association (AHA) guidelines incorporating all the aforementioned metrics, is associated with improved survival from OHCA. ⋯ In this observational study, compliance with AHA guidelines for CPR quality was not associated with improved outcomes from OHCA. Conversely, when restricting the cohort to those with late ROSC, compliance with guidelines was associated with improved clinical outcomes. Strategies to improve overall guideline compliance may have a significant impact on outcomes from OHCA.

Randomized Controlled Trial Comparative Study
Born not breathing: A randomised trial comparing two self-inflating bag-masks during newborn resuscitation in Tanzania.
Effective ventilation is crucial to save non-breathing newborns. We compared standard equipment for newborn resuscitation to a new Upright bag, in an area with high neonatal mortality. ⋯ Upright provided higher expired tidal volume, MAP, PIP and early ECO2 than the standard bag. Clinical outcome differed at 30min, but not at 24h. Larger volume of Upright than standard bag can be an important factor. The results are relevant for low- and high-income settings as ventilatory and heart rate parameters during resuscitation of newborns are rarely reported. Trial registered at www.ClinicalTrials.gov, NCT01869582.

Observational Study
A Novel Educational Outreach Approach to Teach Hands-Only Cardiopulmonary Resuscitation to the Public.
The American Heart Association set goals in 2010 to train 20 million people annually in cardiopulmonary resuscitation and to double bystander response by 2020. These ambitious goals are difficult to achieve without new approaches. ⋯ There is noticeable public interest in learning Hands-Only CPR by using an airport kiosk and an airport is an opportune place to engage a layperson in learning Hands-Only CPR. The average quality of Hands-Only CPR by the public needs improvement and adding kiosks to other locations in the airport could reach more people and could be replicated in other major airports in the United States.

We hypothesised that the use of 50% compared to 100% oxygen maintains cerebral oxygenation and ameliorates the disturbance of cardiac mitochondrial respiration during cardiopulmonary resuscitation (CPR). ⋯ The use of 50% oxygen during CPR results in lower cerebral oximetry values compared to 100% oxygen but there is no difference in brain tissue oxygen. Cardiac arrest disturbs cardiac mitochondrial respiration, but it is not alleviated with the use of 50% compared to 100% oxygen (Ethical and hospital approvals ESAVI/1077/04.10.07/2016 and HUS/215/2016, §7 30.3.2016, Funding Helsinki University and others).
