ECG/RESP Monitoring
11-13
For different patient types, the upper/lower limits of the heart rate alarm may vary in
the following range.
Patient type Max. ALM HI Min. ALM LO Increment (beat/min)
Adult 300 15 1
Pediatric 350 15 1
Neonate 350 15 1
NOTE
z
Always set the alarm limits according to the clinical condition of the
individual patient.
z
In many cases, the upper limit of heart rate alarms should not exceed 20
beats per minute higher than the patient's heart rate.
„ HR FROM Heart rate source
Options: ECG, SPO2, AUTO and BOTH
1. ECG: The monitor detects the heart rate through the ECG.
2. SPO2: The monitor detects the heart rate through the SPO2. PULSE is
displayed to the right of the ECG label while the PR (pulse rate) value is
displayed below. The monitor activates pulse beeps instead of heartbeat beeps.
Besides, the monitor gives indications to PR alarms but gives no indication to
the HR alarms.
3. AUTO: The monitor determines the heart rate source depending on the signal
quality. The ECG takes priority of the SPO2. The SPO2 is selected as the heart
rate source only if the quality of the ECG signal is too poor to be analyzed.
Once the ECG signal restores to normal situation, it is selected as the heart rate
source again.
4. BOTH: The monitor displays both the HR and the PR values. The later is
displayed at the right of the SPO2 label. The monitor will alarm for both
abnormal HR and PR. HR is given priority in determining the source of the
beep tone. If HR is not available, the sound will be from the PR.
