Alarm Name/Mitigation/Resolution
2410
Heart Rate High
The heart rate is greater than the High Heart Rate Limit. The default value for the limit is 120 beats/
minute.
Mitigation/Info: Heart Rate Above Limit
**Consult Physician**
2411
Heart Rate Low (Pulse Rate Low)
The heart rate is less than the Low Heart Rate Limit. The default value for the limit is 40 beats/
minute.
Mitigation/Info: Heart Rate Below Limit
**Consult Physician**
3091
Incomplete Exhalation
The exhaled flow from the patient continues throughout the expiratory period causing the expiratory
control valve to cycle throughout the period to maintain the baseline pressure.
Mitigation/Info: Incomplete Exhalation, Increase Expiratory Time, Decrease Inspiratory Time,
Decrease Respiratory Rate
**Consult Physician**
3092
Patient Inspiratory Demand Not Met
The end Inspiratory P
eliminate nuisance alarms when the patient takes a single deep breath.) This can occur due to
changes in the patient's status, where the patient will attempt to inspire more gas than what is
currently being delivered.
Mitigation/Info: Patient Breathing/Fighting with Vent?, Increase Flow Rate or Reduce Rise Time,
Adjust Alarm Settings if Required, Consult Physician
**Manually Ventilate Patient**
3313
SpO2 Signal Interference
An outside signal or energy source prevents accurate reading by the device.
Mitigation/Info: External Signal Interfering With Measurement, Remove Patient from Location
**Turn Off Pulse Ox Monitoring**
3317
Low SpO2 Perfusion (Low Perfusion)
The amplitude of the arterial pulsation is weak. Low perfusion typically occurs in patients with poor
circulation or when the sensor is applied to the same limb as the noninvasive blood pressure
(NIBP) cuff.
Mitigation/Info: Arterial Pulsation Weak, Check Sensor Placement, Check Sensor Operation
**Turn Off Pulse Ox Monitoring**
3318
Low SpO2 Perfusion (Poor SpO2 Signal)
The pulse oximeter determines the quality of the input signal is low due to excessive motion or
artifact.
Mitigation/Info: Signal Artifact, Minimize Patient Movement, Check Sensor Placement, Check
Sensor Operation
**Turn Off Pulse Ox Monitoring**
