Since originally writing this blog post, in early 2021 I began using a very high starting IPAP of 18.2 cmH2O and EPAP of 12.8 cmH2O (inhale and exhale pressure) which may cause air coming out the eyes. Top pressure during the night may be more than 20 cmH2O! This was essential to stop hypoxia (oxygen desaturation) and sleep disordered breathing causing the symptoms of Dementia.
