Randomized Controlled Trial Comparative Study
Comparison of pressure support ventilation and T-piece in determining rapid shallow breathing index in spontaneous breathing trials.
The threshold values of rapid shallow breathing index (RSBI) were compared in pressure support ventilation (PSV) and T-piece assessments for spontaneous breathing trials (SBT). The ability of ΔRSBI to also predict successful weaning was evaluated. ⋯ The threshold values of RSBI, thus 75 breaths per min/L (PSV) and 100 breaths per min/L (T-piece), for predicting successful weaning were more accurate than other values. Similarly, the change in the RSBI could also predict such successes.
