ECG setting in measurements
Figure 11-7 ECG Setting menu
1.
ALM ON/OFF(alarm On/off):When the heart rate alarm happens. Select ―OFF‖
will be
prompted beside ECG.
2.
ALM LEV(Alarm level): three options: High, MED and Low, and High is for the most serious alarm.
3.
ALM REC(Alarm record): Users can select ―On‖ to print HR alarms when they happen
4.
Lead type: 5-lead or 3-lead
5.
HR CHANNEL(Selection of HR calculation channel )
―Channel 1‖ means the HR is calculated according to the first ECG waveform data.
―Channel 2‖ means the HR is calculated according to the second ECG waveform data.
―Auto‖ means the monitor will automatically select the channel of calculating HR.
6.
HR FROM(HR Source)
Users can select to check HR through ECG or PLETH (blood-oxygen volume recording waveform); if
users select ―Automatic‖, the monitor will decide HR source based on signal quality; if users select
―All‖, the monitor will concurrently display HR and PR. In case PLETH is taken as the HR source, the
PULSE reminder will be displayed together with pulse voice.
In case PLETH is taken as HR source, no alarm judgment on HR but alarm judgment on PR will be
conducted. In case ―All‖ is selected, PR measurement values will be displayed in the right to SpO
2
on the main screen, and HR & PR make alarms at the same time. Pulse voice will give priority to
HR, as long as there is HR data, voice reminder will be there; only when there is no HR data, voice
reminder will be subject with PR.
