Randomized Controlled Trial
The Effect of Airway Management on CPR Quality in the Paramedic2 Randomised Controlled Trial.
Good quality basic life support (BLS) is associated with improved outcome from cardiac arrest. Chest compression fraction (CCF) is a BLS quality indicator, which may be influenced by the type of airway used. We aimed to assess CCF according to the airway strategy in the PARAMEDIC2 study: no advanced airway, supraglottic airway (SGA), tracheal intubation, or a combination of the two. Our hypothesis was that tracheal intubation was associated with a decrease in the CCF compared with alternative airway management strategies. ⋯ There was no significant difference in the compression fraction associated with the airway management strategy.

Multicenter Study Observational Study
Non-linear association between arterial oxygen tension and survival after out-of-hospital cardiac arrest: a multicentre observational study.
Studies to identify safe oxygenation targets after out-of-hospital cardiac arrest (OHCA) have often assumed a linear relationship between arterial oxygen tension (PaO2) and survival, or have dichotomised PaO2 at a supra-physiological level. We hypothesised that abnormalities in mean PaO2 (both high and low) would be associated with decreased survival after OHCA. ⋯ The mean PaO2 within the first 24-hs after admission for OHCA has a non-linear association with the highest STHD seen between 100 and 180 mmHg. Randomised controlled trials are now needed to validate the optimal oxygenation targets in mechanically ventilated OHCA patients.

Early outcome prediction for out-of-hospital cardiac arrest with initial shockable rhythm is useful in selecting the choice of resuscitative treatment by clinicians. This study aimed to develop and validate a machine learning-based outcome prediction model for out-of-hospital cardiac arrest with initial shockable rhythm, which can be used on patient's arrival at the hospital. ⋯ A favourable machine learning-based prognostic model available to use on patient arrival at the hospital was developed for out-of-hospital cardiac arrest with initial shockable rhythm.

Cardiopulmonary resuscitation (CPR) in the delivery room (DR) after birth is rare. We hypothesized that factors related to maternal, delivery, infant and resuscitation event characteristics associated with outcomes could be identified. We also hypothesized there would be substantial variation from the Neonatal Resuscitation Program (NRP) algorithm. ⋯ In this cohort of infants receiving chest compressions following delivery, recognizable pre-birth risk factors as well as resuscitation interventions associated with increased and decreased odds of achieving ROSC were identified. Chest compressions were frequently initiated in the first minute of the event and often prior to endotracheal intubation. Further investigations should focus on methods to decrease time to critical resuscitation interventions, such as successful endotracheal intubation and administration of the first dose of adrenaline, in order to improve DR-CPR outcomes.

Cardiac arrests are often categorized into two separate groups depending on the location of the arrest: in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrest (OHCA). Despite this distinction, few studies have compared the two groups directly. The aim of this study was to compare patient characteristics, cardiac arrest characteristics, and outcomes for IHCA and OHCA patients. ⋯ In this large, national study, we found that IHCA and OHCA patients were remarkably similar in demographics and most comorbidities. IHCA patients had better outcomes compared to OHCA patients, although these differences disappeared when comparing patients with similar cardiac arrest characteristics.
