Metronome - Progetti Chest-eR chest compression guidance device designed to reduce the occurrence of internal injuries. The Chest-eR monitors the patient's chest compressions during CPR and is designed to improve the quality of chest compressions while offering maximum safety.

• Place the Chest-eR on the patient's chest (as shown in the diagram), press it, and the device will activate automatically.
• A light indicator will show the pressure and compression rate applied for chest compression. A green light indicates it is correct, and a red light indicates it is incorrect.
• If the rescuer continues to apply force preventing the chest from returning to its original position, both red lights will turn on to warn the rescuer to release the pressure.
• Once the chest compression is completed, the device will automatically deactivate after 30 seconds of non-use.
