What is a common characteristic of both Zoll Auto-Pulse and Physio-Control Lucas Devices?

Both the Zoll Auto-Pulse and the Physio-Control Lucas Devices are designed for use in cases of cardiac arrest, specifically focusing on delivering continuous chest compressions. This capability is essential in any cardiac arrest scenario, where the primary goal is to maintain blood circulation until advanced medical help can take over.

The indication for non-traumatic cardiac arrest is significant because it emphasizes the devices' role in scenarios that are primarily related to cardiac conditions rather than those caused by external injuries. This characteristic sets a clear application area for both devices and supports their design and functionality based on the physiology of cardiac arrest.

Other options, such as indications for pediatric patients, manual CPR instructions, and operation without a power supply, do not accurately describe the commonalities between these two devices. They are primarily used for adult patients and require a power source to function effectively, thus reinforcing the importance of their use within the correct context of non-traumatic cardiac arrests.
