Figure 5 shows how the Philips IntelliVue Monitor can display TOF-results generated by the
TetraGraph system, for each label as seen in Figure 4.
Figure 5
. Screen shot from when Philips IntelliVue monitor can display TOF-results given by
TetraGraph system.
In Figure 5 the TOF bar-wave shows four TOF responses in which the TOF ratio is 89 %.
The custom label- NMT displayes a numeric value of 89 which is further emphasized by the
TOFrat 89.
The purpose of the NMT numeric is to hold TOF Ratio, TOF Count as well as PTC values. This
means that if the level of neuromuscular block would be as deep as TOFc 2 then the NMT
would display a numeric value of 2 and further emphasized with a TOFcnt 2, as seen in
Figure 6. When in PTC mode, the result will show both in the NMT numer as well as a PTC
value on the Philips display.
