Severe accidental hypothermia (<28 °C) is a rare occurrence, it may induce cardiac
arrest (CA).
1
Hypothermia induced CA is fundamentally different from primary CA.
2
The hypothermic heart may be unresponsive to defibrillation and resuscitative drugs.
3
Extracorporeal life support (ECLS) is the recommended rewarming method for selected
arrested hypothermic patients.

Hypothermia reduces the metabolism, thereby protecting the brain in no and low blood-flow
states. Outcome of arrested hypothermic compared to normothermic patients is substantially
better, even if cardiopulmonary resuscitation (CPR) lasts for several hours.

In hypothermic patients witnessed CA is called rescue collapse (RC).

Until now, the influence of rescue collapse on survival in hypothermic arrested patients
is not determined. Rescue collapse should be avoided, but if it occurs it is considered
reversible with early and continuous CPR and ECLS rewarming. In this issue, Podsiadło
et al. address the implications of rescue collapse on survival and the course of in-hospital
therapy. Moreover, they report risk factors for rescue collapse.
