Train Of Four Mode (Tof); Double Burst Mode (Db) - Xavant STIMPOD NMS 410 Manual

3.4) Train of Four Mode (TOF)

The TOF stimulation comprises four, square waves with a pulse width of 200 microseconds,
500 milliseconds apart.
Selecting TOF Mode:
•
Insert the NMBA cable with the red and black electrode clips as well as the tri-axial
accelerometer.
•
Ensure that TOF is one of the selected Active Modes in the NMT Settings menu (4.3).
•
Press the 'Mode' button until 'TOF' is shown on the display.
Real-time Accelerometry:
•
The relative contraction strength caused by each stimulus is indicated graphically in
the diagnostic screen as shown in the picture.
•
In the case that all four contractions could be measured, the percentage of measured
contraction strength of the fourth stimulus compared to the first stimulus will be
displayed in the diagnostic screen.
•
If less than four contractions were measurable, the number of contractions that could
be identified by the accelerometer will be displayed, e.g., 2/4.

3.5) Double Burst Mode (DB)

The DB stimulation comprises a burst of three square waves of 200microseconds pulse
width, 20 milliseconds apart, followed by another burst of three square waves, 750
milliseconds later.
Selecting DB Mode:
•
Insert the NMBA cable with the red and black electrode clips as well as the tri-axial
accelerometer.
•
Ensure that DB is one of the selected Active Modes in the NMT Settings menu (4.3).
•
Press the 'Mode' button until 'DB' is shown on the display.
Real-time Accelerometry:
•
The relative contraction strength caused by each stimulus is indicated graphically in
the diagnostic screen as shown in the picture.
•
The percentage of the measured contraction strength of the second contraction
compared to the first contraction will be displayed in the diagnostic screen.
