Human factors engineers have developed a CPR machine that allows people without CPR training to save the lives of those who are suffering from cardiac arrest. It monitors, and gives feedback about, actions such as the depth of chest compressions. The device consists of a pressure-sensing headrest, an anesthesia mask, defibrillator pads, a monitor, and speakers that talk the user through the procedure step by step.
During a medical emergency, seconds can mean the difference between life and death. Each year in the United States, 300,000 people suffer cardiac arrests, yet studies show only 1 percent of the public have proper CPR training.
