Real-time measurement of end-tidal carbon dioxide (ETCO2) is used as a non-invasive estimate of cardiac output and perfusion during cardiopulmonary resuscitation (CPR). However, capnograms are often distorted by chest compressions (CCs) and this may affect ETCO2 measurement. The aim of the study was to quantify the effect of CC-artefact on the accuracy of ETCO2 measurements obtained during out-of-hospital manual CPR. ⋯ CC-artefact causes ETCO2 measurement errors in the two studied devices. This suggests that capnometer algorithms may need to be adapted to reliably perform in the presence of CC-artefact during CPR.

Emergency life-saving technicians (ELSTs) are specially trained prehospital medical providers believed to provide better care than basic emergency medical technicians (BEMTs). ELSTs are certified to perform techniques such as administration of advanced airways or adrenaline and are considered to have more knowledge; nevertheless, ELSTs' effectiveness over BEMTs regarding out-of-hospital cardiac arrest (OHCA) remains unclear. We investigated whether the presence of an ELST improves OHCA patient outcomes. ⋯ Compared with the BEMT group, transport by the ELST group was associated with better neurological outcomes in OHCA.

Patients who suffer in-hospital cardiac arrest (IHCA) are less likely to survive if the arrest occurs during nighttime versus daytime. Diastolic blood pressure (DBP) as a measure of chest compression quality was associated with survival from pediatric IHCA. We hypothesized that DBP during CPR for IHCA is lower during nighttime versus daytime. ⋯ In this cohort of pediatric ICU patients with IHCA, there was no significant difference in DBP during CPR between nighttime and daytime.

To examine the association between heat index (HI) during the induction, maintenance, and rewarming periods of targeted temperature management (TTM) and neurologic outcome in out-of-hospital cardiac arrest (OHCA) survivors. ⋯ Heat generation was independently associated with neurologic outcome in OHCA survivors who underwent TTM at 33 °C. The performance of HI was higher in the rewarming period than in the induction or maintenance period in association with poor neurologic outcomes.

Observational Study
Analysis of Visual Attention and Team Communications during Neonatal Endotracheal Intubations using Eye-tracking: An Observational Study.
Eye-tracking can be used to analyse visual attention (VA) of health care providers during clinical tasks. No study has examined eye-tracking during neonatal endotracheal intubation. We aimed to examine VA and team communications during endotracheal intubation using eye-tracking in the Neonatal Intensive Care Unit. ⋯ During neonatal intubations, 50% of VA was directed away from the infant. Team communications were non-standard. Eye-tracking can be used to analyse human performance during neonatal resuscitation.
