TOF ratio: onset versus spontaneous recovery

• The train of four (TOF) ratios can be demonstrated to differ during onset and offset of NDMR effects

• These are scientific measurements, dependent on transducer printouts and of limited clinical significance

ratio at onset and recovery, with greater difference (ratio) during recovery. Note:no train of 4 ratio at onset (arrow)
