Tetragraph

Quantitative Monitoring of Neuromuscular Blockade

TetraGraph is a quantitative neuromuscular transmission monitor which is easy to use and features gold standard EMG technology for accurate measurements, bringing confidence to your anesthesiology practice.

Through the accurate meaurements, TetraGraph supports your neuromuscular blockade management from start to finish during the surgical procedure and helps you to confirm a train-of-four ratio ≥ 0.9 prior to extubation.

In addition, the monitor has a quick start up-time and does not require calibration. The patient’s arm can be tucked under surgical drape and can thus be used in all types of procedures.

PATIENT SAFETY IN YOUR HANDS

Description
Modes of Operation

TOF mode is the TetraGraph’s main mode of operation. A sequence of four stimuli, at a frequency of 2 Hz, referred to as Train-of-Four (TOF) is delivered to the peripheral nerve and the Train-of-Four Ratio (TOFR, or the ratio of the amplitude of the fourth twitch T4, to that of the first twitch, T1) and the TOF Count (TOFC, or the number of discernable twitches) of the evoked EMG responses are calculated and displayed.

TOF stimulation is used to assess the depth of neuromuscular blockade and gauge the degree of recovery after reversal. Other operating modes are Post-Tetanic Count (PTC), which is used to determine NMBA management during surgeries that require deep block, and Single Twitch, which is used to deliver a single stimulus and display a single muscle response in millivolt (mV).
