BMT were: clinical interview, arterial blood gas (ABG) and home nocturnal oximetry (HNO). HMV was satisfactory (S-HMV) if the following criteria were met: 1-Comfort and improvement of symptoms, 2-ABG: pO2\>60 mmHg and pCO2\<46 mmHg, 3-HNO: SpO2 time \< 90\% (T90) \< 20\%, and 4-BIS analysis: compliance \>4 h/night, respiratory rate \<25 breaths/min, average leak \<60 L/min (facial mask) and \<50 L/min (nasal mask), and asynchronies in \<50\% of the whole record (pressure slope). HMV was unsatisfactory (U-HMV) if any of the criteria fail. Changes in treatment were recorded. Vivo 30/40 and their BIS were used in all cases.RESULTS: Fifty patients aged 60(9) yrs, 60\% male and 21(7) months under HMV were included. Conditions were: 29 Obesity-hypoventilation, 5 chest wall disorders, 4 neuromuscular diseases, 4 COPD and 8 mixed conditions. Thirteen cases (26\%) were S-HMV. Seventy-nine U-HMV causes were detected, 34 by BIS and 45 by BMT. Fifty-nine changes were made in 33 patients: 15 interfaces, 15 ventilator settings, 11 harnesses, 5 added humidifier, 5 added O2, 5 withdrew O2 and 3 changes of ventilator. BIS detected 12 (32\%) of the 37 U-HMV cases with no abnormalities in BMT.CONCLUSIONS: Applying simple criteria to the analysis of ventilator BIS increases our ability to detect U-HMV and promotes changes that could improve the quality of treatment.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P3856}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P3856.full.pdf}, journal = {European Respiratory Journal} }
