Table 1. Muscle Function during Recovery from Residual Meeting Abstracts in Relation to TOF Ratio (n = 12)

Accelerometric and spirometric data are presented as mean ± SD. Upper airway obstruction was defined as a mean ratio of expiratory and inspiratory flow at 50% of vital capacity of greater than 1. Even with the greatest degree of paralysis, fade of thumb adduction was visible only in a single patient, and inability to sustain a head lift was seen in another patient. In contrast, at train-of-four (TOF) ratios of 0.5 and 0.83, upper airway obstruction was observed in 8 and 4 of 12 volunteers, respectively. Swallowing and ability to approximate lips to seal a mouthpiece were impaired in many volunteers until TOF ratio had recovered to unity.

*P < 0.05 vs.  TOF recovery to 1.02 ± 0.01.
