The ILCOR COVID-19 consensus aimed to balance the benefits of early resuscitation with the potential for harm to care providers, stating, notably, that every emergency system should react according to its resources and its region’s evolving disease prevalence.
Since the start of confinement in France (March 17, 2020), the Paris Fire Brigade prehospital emergency system was faced with the need to adapt its OHCA rescue chain. First, the dispatcher performed phone detection of OHCAs using the “hand over belly” technique, which showed its effectiveness in our system in the recent past.
Indeed, insofar as this procedure kept the bystander away from the patient’s airway, it seemed quite safe. After asking the bystander to open the windows of the room to disperse a potential viral atmosphere, the dispatcher instructed him to perform chest compressions (CCs).
Second, the lockdown resulted in suspending our regional mobile lay-responder application, because mobile-responders had no personal protection equipment (PPE) at this time. Third, the AED-location map from this application failed to be helpful as most public places were closed. Fourth, the dispatch of the Basic Life Support (BLS) teams was limited to one crew per-patient instead of the two provided for in the pre-pandemic period, to limit rescuers’ viral exposure and to keep BLS teams available to treat the dramatically increased number of OHCAs that occurred during this period (Fig. 1).
Their response time was unchanged, because of reduced road traffic, with a median [interquartile range] drive time of 5 min 36 s [3 min 49 s–7 min 32 s] versus 5 min 10 s [3 min 33 s–7 min 29 s] before the lockdown period. Other BLS procedure adaptations were following ILCOR recommendations. As the Parisian system ensures the reinforcement of BLS teams by a prehospital emergency physician, the latter systematically employed a mechanical CC device to replace the manual CCs and limit the teams’ viral exposure. The physician performed orotracheal intubation wearing a hooded suit and ski mask and using video laryngoscopy.
Breaking out of confinement, which corresponds with the decrease in regional disease prevalence, requires restoring the lay-responder app and easing the BLS teams’ protection to save time in their CPR initiation. COVID’s decreasing prevalence makes it difficult for the dispatcher and the BLS team to differentiate COVID from non-COVID OHCAs instantly. Unfortunately, for some patients, this may result in inappropriate measures.
Finally, the emergency system’s responsiveness remains essential for a balanced adaptation of the rescue procedures to the pandemic’s evolution, any viral changes, and future scientific advances. In this context, the collection of accurate data remains more essential than ever.
