The impact of changing people with sleep apnea using CPAP less than 4 h per night to a Bi-level device
2015
Summary Pressure intolerance is a reason for poor acceptance and subsequent compliance in some patients starting treatment with continuous positive airway pressure (CPAP). In unselected populations initiating CPAP; different types of pressure generating device have not been found to improve compliance. We hypothesized that using Bi-level PAP for patients who reported pressure related discomfort as a cause for poor compliance with CPAP might increase their hours of treatment use. Patients using CPAP Twenty eight volunteers completed the protocol. Compared to the baseline (mean 1.49 h per night), improvement in compliance was noticed when changed to a new CPAP (2.23 h, p = 0.006) or Bi-level PAP (2.73 h, p The results of this study suggest that routine intervention with Bi-level PAP in this group of sub-optimally compliant individuals was not very effective in improving PAP usage. There is however a subgroup of patients who complains of difficulty with exhalation; where favorable trends towards improved compliance were observed on Bi-level PAP.
