Health care experts worry that medical devices with built-in alarms – such as heart monitors, infusion pumps and ventilators – designed to alert caregivers that patients are in danger could potentially put patients at risk because caregivers are desensitized by the sheer number of alerts and false alarms and fail to respond in a timely fashion. Research shows alarms in intensive care units are accurate less than 10 percent of the time,and 90 percent are false alarms.
