A team of investigators at Vanderbilt University Medical Center (VUMC) wants to improve patient outcomes in Intensive Care Unit (ICU) settings by silencing audible medical alarms in hospital rooms” Vanderbilt University Medical Center (2017).

Vanderbilt University Medical Center report “A team of investigators at Vanderbilt University Medical Center (VUMC) wants to improve patient outcomes in Intensive Care Unit (ICU) settings by silencing audible medical alarms in hospital rooms.

Auditory medical alarms have created hazards for patient recovery, said Joseph Schlesinger, M.D., assistant professor of Anesthesia, Division of Critical Care Medicine at Vanderbilt. His team has created a device that removes the alarm sounds while preserving the patient’s ability to hear human and environmental stimuli, notably speech.

The findings, “Frequency-Selective Silencing Device for Digital Filtering of Audible Medical Alarm Sounds to Enhance ICU Patient Recovery,” were presented at the International Community for Auditory Display (ICAD) at Penn State this week. The paper highlights how loud noises produced by clinical alarms contribute to psychological problems like delirium and PTSD and provides innovative solutions to enhance the patient experience.”
