All cardiac arrests - B. Paediatric cases only - C. Challenging situations - D. To replace manual CPR Answer: C. Challenging situations The current Guidelines agree: Manual CPR remains the standard, but mechanical CPR is valuable when manual compressions are difficult or unsafe. Both Guidelines highlight key scenarios, including prolonged CPR, transport, and procedures in the cath lab where consistent, uninterrupted compressions are essential. **Did you know?** The ZOLL® AutoPulse® NXT Resuscitation System delivers consistent, uninterrupted compressions in transport and cath lab settings.
