At the Hospital of Central Connecticut in New Britain, health care professionals are adopting techniques from aviation safety experts to reduce the chances of a catastrophic event happening before a clinical alarm goes off. These are among the many ways Connecticut hospitals are tackling a phenomenon known industry-wide as alarm fatigue. 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.
