Our coordinating center said it was a cardiac arrest: Shall we believe them?

s / Resuscitation 96S (2015) 43–157 49 CA identified by CCU were not actual CA, but only 57.57% received CPR by ALS team. Resuscitation was not attempted due to: time of collapse unknown, 15.90% of cases; long interval collapse-CPR attempt, 8.33%; bad biological situation, 10.60%; unknown causes 5.30%. 58.13% of calls identified as CA by CCU were confirmed by ALS, Only 49% of the CA identified by ALS were recognized by CCU, 35% of CA calls were labelled as “unconscious patient”. Other significant mistaken activations labels are dyspnoea, drowning and intoxications. Conclusions: Our CCU must improve the recognition of CA on calls, specificity is high but not as sensitive as desirable. Once CA call is labelledwe should try to recall better information to identify patients in which CPR should not be performed. http://dx.doi.org/10.1016/j.resuscitation.2015.09.112 Airway & Ventilation
