AbstractOur study aimed to understand the characteristics of ventilator dependence in patients at a respiratory care center and the potential effects of physical therapy on ventilator weaning and patients' functional status. Prospective data collection consisted of the following: (1) demographic data, including name, gender, age, diagnosis, the Acute Physiology and Chronic Health Evaluation as a severity of the disease, modified Glasgow Coma Scale, mobility at the time of admission, and days of hospitalization; (2) Rapid shallow breathing index (RSBI) as a predictive indicator of ventilator weaning, including indicators of ventilator weaning were collected from the respiratory flow sheet; and (3) Barthel index. Between July 1 and December 31, 2007, 126 patients were admitted to the respiratory care center, and those who required mechanical ventilation for more than 14 days were enrolled. Fifty-five subjects received physical therapy. The RSBI in patients who received physical therapy was 75.7 +/- 37.9 before therapy and 80.0 +/- 48.5 afterwards, while the Barthel index increased from 0.8 +/- 1.4 to 1.9 +/- 2.5 (p < 0.05). The RSBI decreased as time of physical therapy lengthened, but not significantly (r = 0.12, p = 0.44). The success rate of ventilator weaning in patients receiving physical therapy intervention versus non-physical therapy intervention was 58.2% and 40.9%, respectively. The results indicated that lengthening the physical therapy intervention time enhanced the ventilator weaning success rate while mobility was not affected (r = -0.11, p = 0.41). Physical therapy may be offered to ventilator-dependent patients in line with their individual needs to improve or maintain basic mobility.Copyright 2010 Elsevier. Published by Elsevier B.V.
