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
Typical clinical TOF responses• Atracurium blockade: Note differences in TOF
ratio at onset and recovery, with greater difference (ratio) during recovery. Note:no train of 4 ratio at onset (arrow)
