Correlation between Handgrip Strength and Rapid Shallow Breathing Index for Assessment of Weaning from Mechanical Ventilation

Table 2

Comparison of handgrip strength and rapid shallow breathing index between weaning success and weaning failure.

Variable	Total, n = 93	Weaning success, n = 87	Weaning failure, n = 6	value
HGS at 48 h after intubation, kg	15.6 ± 7.0	16.2 ± 7.3	6.8 ± 4.7	0.002
HGS at 10 min before SBT, kg	15.8 ± 6.7	16.3 ± 6.5	8.2 ± 5.3	0.004
HGS at 30 min before SBT, kg	15.9 ± 6.6	16.4 ± 6.3	8.6 ± 5.6	0.004
HGS 1 h after extubation, kg	16.3 ± 6.5	16.8 ± 6.3	8.6 ± 5.5	0.002
RSBI at 10 min before SBT, breaths/min/L	40.2 ± 9.2	40.0 ± 8.9	42.2 ± 14.4	0.590

Data are presented as mean ± SD. HGS, handgrip strength; RSBI, rapid shallow breathing index; SBT, spontaneous breathing trial.
