94 Chapter 5 Respond to alarms and alerts
Respond to an arrhythmia NOISE alert
The visual NOISE alert occurs when the Acuity System can't analyze arrhythmia because
of excessive electrical noise.
The Acuity System invalidates individual noisy leads and then re-validates them when
noise is no longer detected.
At the Acuity Central Station, there is no heart rate reading during this alert, but the
patient monitor might present a heart rate.
To respond to an arrhythmia NOISE alert
1. Verify that the patient's lead wires and electrodes are in good condition.
2. Verify that the electrodes were placed using standard good practices.
