Seismocardiography measures the vibrations produced by the beating heart using an accelerometer sensor placed on the chest. We evaluated the ability of smartphone seismocardiography to distinguish between the presence and absence of spontaneous circulation. ⋯ In conclusion, blinded observers accurately distinguished between seismocardiography signals from patients with and without spontaneous circulation.

Expired Carbon Dioxide during Newborn Resuscitation as Predictor of Outcome.
To explore and compare expired CO2 (ECO2) and heart rate (HR), during newborn resuscitation with bag-mask ventilation, as predictors of 24-h outcome. ⋯ Higher levels and a faster rise in ECO2 and HR during newborn resuscitation were independently associated with improved survival compared to persisting low values. ECO2 increased before HR and may serve as an earlier predictor of survival.

The emergency department (ED) plays an important role in out-hospital-cardiac arrest (OHCA) management. However, ED outcomes are not widely reported. This study aimed to (1) describe OHCA ED outcomes and reasons for ED deaths, and (2) whether these differed between hospitals. ⋯ Our study found wide variation in survival between EDs, which was associated with hospital characteristics. Such data suggests the need for a detailed review of ED deaths, particularly in non-cardiac arrest centres, and potentially the need for monitoring ED survival as a measure of quality.
