Changing the NMT cycle time
This selection also affects the recovery note.
1. Select the NMT parameter window > Setup .
2. Select a value from the Cycle Time list.
Changing the NMT pulse width
1. Select the NMT parameter window > Setup .
2. Select a value from the Pulse Width µs list.
Adjusting the NMT beep volume
You can set the beep value to best suit your care environment.
1. Select the NMT parameter window > Setup .
2. Select a value from the Stimulus Beep Volume list.
Using the NMT recovery note
The recovery note alarms you with a single beep and the Block recovery message
when the count reaches the value you have selected. It indicates that the patient is
responding more clearly to the stimuli and the neuromuscular block is decreasing.
The note is activated according to the count number and cycle time:
●
Cycle time less than one minute: The count must be below the selected limit in
two consecutive measurements.
●
Cycle time one minute or more, or manual measurement: At least one count must
be below the selected limit.
To take this feature into use:
1. Select the NMT parameter window > Setup .
2. Select Recovery Note .
3. Select the count limit that will activate the note.
Measuring deep relaxation
When no responses are detected for TOF stimulation, the post tetanic count (PTC) is
the only way to measure the neuromuscular block. A tetanic stimulation (50 Hz) is
generated for five seconds and post-tetanic responses to single-twitch stimulation
are counted. The larger the PTC (the number of detected responses), the sooner the
normal TOF responses return. To monitor the relaxation level, start a five-second
tetanic stimulation:
1. Select the NMT parameter window > Setup .
2. Select Start Tetanic/PTC .
Continuing the NMT measurement
To continue interrupted NMT measurement with the same patient and monitor, press
the
Stop Continue module key, or:
1. Select the NMT parameter window > Setup .
