ECG/RESP Monitoring
■ ECG alarm setting
HR ALM: pick "ON", the system will give alarm and save the alarm information when
HR alarm occurs; pick "OFF", the system will not give alarm and instead display a ^fe
beside "ECG".
ALM LEV: three options are available, which are HIGH, MED, LOW. Level HIGH
means the most serious case.
ALM REC: pick "ON", the system will start recording process once HR alarm occurs.
ALM HI: used to set up the upper limit of ECG alarm.
ALM LO: used to set up the lower limit of ECG alarm.
ECG alarm is activated when the heart beat exceeds the ALM HI value or falls below the ALM
LO value.
ECG alarm limits:
Max. ALM HI Min. ALM LO Step
HR ADU 300 15 1
HR PED 350 15 1
HR NEO 350 15 1
A A Note
You shall set up the alarm limits according to the clinical situation of the individual
patient. The upper HR alarm limit is very important during clinical monitoring, which
shall not be a very high value. You shall set up the higher HR alarm limit to a value at
most 20beats/min higher than the patient's heart beats.
■ HR FROM
You can select the HR FROM. The ECG signal can be from ECG or SPO2. ECG takes priority
over SPO2. You shall choose SPO2 as the HR source only when the ECG signal is too poor
to be used for analysis. Moreover, when ECG signal becomes normal, the system will
automatically switch the HR source back to ECG waveform. If you select AUTO, the system
will decide the HR source by itself according to the signal quality. If you select BOTH, the
system will display HR and PR (pulse rate) at the same time. If the HR source is SPO2, the
system will display "PULSE" at the right side of ECG hot key and give PR sound at the same
time.
When HR source is SPO2, the system will not make judgment on HR alarm. Instead, it will
make judgment on PR alarm.
When HR source is BOTH, the system will display the PR measurement value at the right
side of SpO2 on the main screen and make judgment on HR and PR alarm at the same time.
The heart beat sound will be based on HR. If there are HR data, the system will give
corresponding sound. If there are no HR data, the system will give PR sound.
■ SWEEP
Available options for SWEEP are 12.5, 25.0, and 50.0 mm/s.
