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

Easy to use
Push-button activation, optional calibration and stimulation mode selection are simple and convenient. Stimulation results are shown immediately on an easy-to-use read LCD display.

Designed for use in ICU
TOF-Watch S has been specifically designed to fulfill user requirements in an intensive care setting. In paralyzed, critically ill patients, it provides precise information regarding the degree of relaxation. This enables optimal control of the depth of block, promotes faster recovery of neuromuscular function and spontaneous ventilation and helps avoid dysfunction resulting from prolonged clinical paralysis.

Features
TOF-Watch S possesses a complete range of stimulation patterns for intermittent or continuous application:

• Single twitch (ST) - at 0.1 or 1Hz
• 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 guarantees reliable 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.

Cost effective
TOF-Watch S contributes to accurate NMBA dosing, enhances patient safety and increases the cost effectiveness of treatment.

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 a low current mode.
