ECG
1. Select the HR parameter window.
2. Select the heart rate alarm range from the HR Alarm Range list:
●
30–240 (set and disabled if the Primary HR Source is IntelliRate , AUTO , or
SpO2 ).
●
20–300
NOTE
France only: Available selections are 30–230 and 20–230 .
Selection 30–230 is set and disabled if the Primary HR
Source is IntelliRate , AUTO , or SpO2 .
ECG alarm priorities
You can set the alarm priorities for various ECG alarms through Alarm Setup > Alarm
Priorities > ECG . The allowed priorities are defined in the Care Unit Settings , and
they are password protected.
ECG measurement practicalities
Alternate pulse rate source
The alternate pulse rate source allows clinicians to acquire a pulse rate from a source
other than ECG (Art, Fem, ABP, UAC, or SpO
2
). The following circumstances may
warrant the use of an alternate pulse rate source:
●
Excessive artifact due to an electrical interference from equipment (e.g.,
electrosurgical device).
●
Excessive patient movement causing significant artifact (e.g., seizure activity).
●
Inability to use standard lead placement (e.g., burns).
PDM IntelliRate algorithm
The PDM uses the IntelliRate algorithm. IntelliRate extracts information from multiple
physiological signals (ECG, SpO
2
, Art) and applies rule-based logic to determine which
heart rate source has the highest likelihood of being accurate. By reporting the most
accurate rate, the trended pulse rate is more accurate, and occurrences of false pulse
rate limit violation alarms are greatly reduced. The alternate pulse rate source value
replaces the standard heart rate value in the HR parameter window.
TRAM, E-modules, and telemetry transmitters Auto
algorithm
TRAM, E-modules, and telemetry transmitters use the AUTO algorithm. AUTO selects
the first available heart rate source based on a pre-defined parameter priority:
1. ECG
2. UAC (TRAM and NICU software package only)
3. Art
4. ABP
5. Fem
6. SpO
