The 2025 AHA guidelines state that the routine use of mechanical CPR devices is not recommended for adult cardiac arrest. While these devices may still have a role in limited situations, the guidelines make clear that manual high-quality CPR remains the standard approach for most adult arrests.

The reason is straightforward: studies have not shown better survival with routine mechanical CPR compared with good manual compressions. The AHA does note that these devices may be considered when manual compressions are difficult or unsafe, but they should not replace strong, consistent hands-on CPR in typical scenarios.
