High noise levels negatively affect patient outcomes
As a caregiver, you know that alarm fatigue takes its toll on staff. An environment of noise and stress takes a heavy toll on patients, too, interfering with their attempts to sleep, rest and recover.
Stressful, loud care environments can result in:
Altered blood pressure and heart rates1
Negative effects on the immune system2
Slower healing and increased length of stay2
Lower patient satisfaction3
Time spent responding to nuisance alarms is time lost for direct patient care."

After a traumatic accident, Kathy woke up in ICU. She couldn’t see, speak or breathe on her own—but she could hear everything. In this video, she shares what it was like to bond with a nurse during her time on life support.
Noise pollution: an intrusive issue for critically ill patients
Despite interventions aimed at decreasing noise, sound levels in the ICU far exceed World Health Organization (WHO) noise recommendations, especially at night. Discover the effect of noise on seriously ill patients and the evidence-based strategies you can use to protect them.
Patients’ delirium risk increases with environmental factors like noise, lights and sleep deprivation. ICU patients are especially likely to become delirious—a terrifying experience with dire health consequences.
The good news? Up to 30% of cases can be prevented with non-pharmacological interventions, like making care environments more tranquil.
