Table 1 Definitions of Depth of Neuromuscular Block Based on Subjective and Measured (Objective) Criteria

Depth of block	Posttetanic	Train-of-Four	Subjective	Measured
Depth of block	Count	Count	Train-of-Four ratio	Train-of-Four ratio
Intense (profound) block	0	0	0	0
Deep block	≥ 1	0	0	0
Moderate block	NA	1 to 3	0	0
light (shallow) block	NA	4	Fade present	0.1–0.4
Minimal block (near recovery)	NA	4	No fade	> 0.4 but < 0.90
Full recovery (normal function)	NA	4	No fade	≥ 0.90–1.0
