The experimental protocol for muscle training consisted of an initial load of 30% maximum inspiratory pressure, which was increased by 10% daily. The training was administered for 5 minutes, twice daily, 7 days a week, with supplemental oxygen from the beginning of weaning until extubation. Successful extubation was defined by the ventilation time measurement with noninvasive positive pressure. A vacuum manometer was used for measurement of maximum inspiratory pressure, and the patients' Tobin index values were measured using a ventilometer.Results: The maximum inspiratory pressure increased significantly (by 7 cm H2O, 95% confidence interval [CI] 4–10), and the Tobin index decreased significantly (by 16 breaths/min/L, 95% CI −26 to 6) in the experimental group compared with the control group. The Chi-squared distribution did not indicate a significant difference in weaning success between the groups (Χ2 = 1.47; P = 0.20). However, a comparison of noninvasive positive pressure time dependence indicated a significantly lower value for the experimental group (P = 0.0001; 95% CI 13.08–18.06). The receiver-operating characteristic curve showed an area beneath the curve of 0.877 ± 0.06 for the Tobin index and 0.845 ± 0.07 for maximum inspiratory pressure.Conclusion: The IMT intervention significantly increased maximum inspiratory pressure and significantly reduced the Tobin index; both measures are considered to be good extubation indices. IMT was associated with a reduction in noninvasive positive pressure time in the experimental group.Keywords: inspiratory muscle training, rehabilitation, extubationCader SAde Souza Vale RGZamora VECosta CHDantas EHDove Medical PressarticleInspiratory muscle trainingRehabilitationExtubationGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 7, Pp 437-443 (2012)
