Alarm limits
A Cuff Not Detected or a No Pulses
Detected equipment alert is occurring at
both the patient monitor and Virtual
Monitor, but NIBP is not being monitored.
This condition usually occurs for one of these reasons:
•
The monitor wasn't turned off and on again to clear settings (including
Auto NIBP) before the new patient was connected to it.
•
The monitor was turned off, but CURRENT SETTINGS (including Auto
NIBP) were saved via the monitor’s SYSTEM Menu.
When a patient monitor is set in the auto NIBP mode, the monitor initiates
measurements at the selected auto interval, even when the cuff is not on the
patient.
1. At the patient monitor, Acknowledge the alert.
2. Press NIBP, MANUAL to change the NIBP setting to Manual.
3. Save the current settings to ensure that the problem doesn't persist
after you turn off the monitor. For instructions, refer to the monitor
directions for use.

Table 13. Troubleshooting alarm limits
Problem
Explanation
I set specialized alarm limits before the
patient ID was confirmed, and the limits
changed after confirmation.
WARNING Before you set customized alarm limits for a patient,
confirm the patient’s ID and room number. Otherwise, customized
limits might be lost.
After I disconnected a patient for transport,
I changed the patient’s alarm limits at the
patient monitor. When I reconnected the
monitor to the Acuity System, the alarm
limits changed from what I had set.
WARNING Always check alarm limits when a monitor
reestablishes communication with the Acuity System. If you
change limits at a monitor while it is not communicating with the
Acuity System (for example, during transport or signal dropout),
when you reestablish communication with the system, the limits
might change to Acuity System Presets values.
When I adjust arrhythmia alarm limits,
sometimes heart rate limits change, too.
WARNING If you set the bradycardia alarm limit higher than the
HR lower limit, the Acuity System adjusts the HR lower limit to
the new bradycardia limit. If you set the tachycardia limit lower
than the HR upper limit, the Acuity System sets the HR upper
limit to the new tachycardia limit. In either case, a message
appears in the upper border of the Arrhythmia Alarms Setup
window telling you HR alarm limits have changed.
