Resuscitation

Algorithms to predict shock success based on VF waveform metrics could significantly enhance resuscitation by optimising the timing of defibrillation. ⋯ AMSA, slope and RMS were the best VF waveform frequency-time parameters predictors of termination of VF according to test validity assessment. This a priori can be used for a simplified SVM optimised design that combines the predictive attributes of these VF waveform metrics for improved prediction accuracy and generalisation performance without requiring the definition of any threshold value on waveform metrics.

Survival after out-of-hospital cardiac arrest (OHCA) has increased in recent years, and new data are therefore needed to avoid unsubstantiated statements when debating futility of resuscitation attempts following OHCA in nursing home (NH)-residents. We aimed to investigate the outcome and prognosis after OHCA in NH. ⋯ Nursing home residents resuscitated from OHCA and admitted to hospital have similar survival rates as non-NH-patients when adjusting for known prognostic factors and pre-existing co-morbidity. A policy of not attempting resuscitation in nursing homes at all may therefore not be justified.
