TOF Watch S

TOF-Watch S is a portable instrument belonging to the TOF-Watch® range of neuromuscular transmission monitors. Utilizing acceleromyography principles, it measures neuromuscular block produced by the administration of an NMBA.

Features include push-button activation, optional calibration and stimulation mode selection. Stimulation results are shown on an easy-to-read LCD display.

TOF-Watch S can also be used in an intensive care setting.  It provides information regarding the degree of relaxation.

TOF-Watch S possesses a range of stimulation patterns for intermittent or continuous application:
- Single twitch (ST) - at 0.1 or 1 Hz
- Train Of Four (TOF)
- Slow TOF (user programmable time intervals from 1 to 60 min.)
- Post Tetanic Count (PTC)
- Double Burst Stimulation (DBS 3.3 and 3.2)

A user-selectable slow-TOF stimulation mode is also available.  The user can program the repetition time interval of the train of four stimulation (TOF) within a range of 1 to 60 minutes.

A constant current feature provides stimulation even with increased skin resistance (up to 5 kOhm).

TOF-Watch S has two automatic calibration modes; one at a user predetermined current and one which establishes the supramaximal value of the stimulation current.  Manual gain adjustment is also possible.

Locoregional anesthesia
Removal of the transducer cable enables use of TOF-Watch S as a peripheral nerve stimulator. In this mode, it identifies the presence of the local anesthesia cable and automatically switches to low current mode.

- Two optional calibration modes
- Optional manual gain adjustment
- Clear, large and simple display
- User-definable default values
- Easy-to-clean membrane keyboard
- Low battery warning
- Automatic detection of transducer and stimulation leads
- Low current mode for nerve stimulation
