Chapter 5: ECG Monitoring
■
ECG GAIN
To adjust the size of ECG waveform, select gain value for each lead from ×0.25, ×0.5, ×1, ×2,
×4 and AUTO. In "AUTO" mode, the monitor chooses an appropriate gain automatically.
■
ECG SWEEP
Available options for ECG SWEEP speed are 12.5, 25, and 50 mm/s.
■
ECG FILTER
For noises reduction, smoother waveforms or detailed waveforms, there are three options
for filtering the ECG:
FILTER TYPE
NORMAL
EXTENDED
MONITOR
■
HR AVERAGE
Available options for HR AVERAGE are 4, 8 and 16 sec.
To calculate HR value average, the values are sent per second to averaging section and any
change based on user setting is made in output data.
- Response time of Saadat monitor to HR change with regard to different HR averages is as
follows:
HR= 80 to 120 BPM
HR= 80 to 40 BPM
FREQUENCY RANGES
0.5-40HZ
0.05-100HZ
0.5-24HZ
HR Avg.= 4s

APPLICATION
This mode is applicable in normal situation
In diagnostic application. but the ECG
waveform might have some noises
This mode may reduce interference from
Electrosurgery equipment or can be used
when the system has high noises or doesn't
have equipotential earth.
