Sports activity and paediatric out-of-hospital cardiac arrest at schools in Japan.
Sudden cardiac death during exercise or sports is an important problem among young athletes and non-athletes. An understanding of the epidemiological features of sports-related out-of-hospital cardiac arrest (OHCA) among children is crucial for planning approaches for prevention and better outcomes of paediatric OHCAs. We assessed the characteristics and outcomes of sports-related OHCA among children at schools in Japan to prevent sports-related paediatric OHCA at schools. ⋯ In Japan, 188 schoolchildren experienced OHCAs of cardiac origin occurring during or after sports activity at schools during the 8-year period. Increasing PAD is essential to enhance better neurological outcome after sports-related OHCA among students.

Effect of vertical location on survival outcomes for out-of-hospital cardiac arrest in Singapore.
A large proportion of out-of-hospital cardiac arrest (OHCA) cases occur in high-rise residential buildings. This study aims to investigate the effect of vertical location on survival outcomes and response times. ⋯ Vertical location is associated with OHCA survival probability with a U-shaped response, and this significance remained after adjustment for other significant OHCA variables. This relationship is likely multifactorial and more research is needed to elucidate the various factors.

End Tidal CO2 and Cerebral Oximetry for the Prediction of Return of Spontaneous Circulation During Cardiopulmonary Resuscitation.
End Tidal CO2 (ETCO2) is a reasonable predictor of Return of Spontaneous Circulation (ROSC) in cardiac arrest (CA), though with many limitations. Cerebral Oximetry (CerOx) non-invasively measures brain O2 saturation and correlates with flow. ⋯ Our data shows, both ETCO2 and rSO2 are good predictors of ROSC. We found CerOx superior to ETCO2 in predicting ROSC.

Vital Sign Patterns Before Shock-Related Cardiopulmonary Arrest.
Traditional vital sign thresholds reflect an increased risk of mortality, which may occur hours, days, or weeks following illness/injury, limiting immediate clinical significance to guide rescue therapy to avoid arrest. Our objective is to explore vital sign patterns prior to arrest due to shock. ⋯ Vital sign patterns were defined for SBP, MAP, HR, shock index, and EtCO2 with clear inflection points identified 2-5 min prior to arrest. These patterns may help guide therapy to reverse deterioration and prevent arrest.

Cerebral oximetry (rSO2) may be useful in assessing the probability of return of spontaneous circulation (ROSC). However, the potential of assessing the trend in the rSO2 value has not been discussed when determining the probability of ROSC. ⋯ The combination of rSO2 (baseline) with the amount of maximum rise in rSO2 value over time might be a new index for the prediction of ROSC that could be useful in guiding cardiopulmonary resuscitation. Further studies are needed to validate these findings.
