Monitoring
TOF ratio screen display
Muscle response to each individual pulse is meas-
ured and displayed as a bar graph.
The ratio of the fourth pulse to the first pulse, T4/T1,
is displayed as a TOF ratio in %, e.g. 48.
After 15 seconds, the last measured value is de-
leted. The time until the next measurement is dis-
played as a bar graph.
TOF count screen display
If fewer than 4 stimulation pulses are detected, the
TOF count value is displayed, e.g., 1.
TOF count – number of pulses that produced a re-
sponse.
For TOF count, an upper and a lower alarm limit
can be set, see page 163.

A 50 Hz signal is applied for 5 seconds. After a
pause of 5 seconds, there will be up to 20 1 Hz sig-
