Primary Outcome Measures

Name	Time	Method
A significant difference was found between the RSBI obtained from the ventilator and by the digital respirometer (p=0.011). The two methods exhibited high interrelation. There was a close correlation between RSBI (ICC=0.86), a moderate concordance related to MV (ICC=0.74) and high concordance related to RR (ICC=0.8) and VT (ICC=0.79) were observed. To all variables the p-value was < 0.05.[The RSBI assessed in each patient during one session only. Statistical analysis undertaken on completion of all data collection.]
