Respiratory and hemodynamic responses to mobilization of critically ill obese patients.

PURPOSE The aim of this study was to investigate the effects of mobilization on respiratory and hemodynamic parameters in critically ill obese patients. METHODS Critically ill obese patients (n = 31) were included in this retrospective study. Data were collected from patients' files and physiotherapy records of mobilization sessions. Heart rate (HR), systolic/diastolic/mean blood pressure, respiratory rate (RR), and percutaneous oxygen saturation (SpO(2)) were recorded. Cardiorespiratory parameters were collected just prior to the mobilization, just after the completion of the mobilization and after 5 minutes recovery period. Respiratory reserve was calculated before and after the mobilization. RESULTS A total of 37 mobilization sessions in 31 obese patients (mean age: 63.3 years, mean BMI: 32.2 kg/m(2)) who received physiotherapy were analyzed. Respiratory rate increased significantly after the completion of the mobilization compared to initial values (p < 0.05). SpO(2) significantly increased (p < 0.05) and all other parameters remained similar (p > 0.05) compared to initial values after the recovery period. Mobilization resulted in a significant increase in respiratory reserve (p < 0.05). CONCLUSION Early mobilization in intensive care unit promotes respiratory reserve in obese patients. We found that mobilization can be performed safely in critically ill obese patients if cardiorespiratory parameters are continuously monitored.
