Physical Sensor Driven Approach for Optimizing Positive Airway Pressure Therapy

Obstructive sleep apnea (OSA) is a sleep disorder for which continuous positive airway pressure (CPAP) therapy is an effective treatment. In this study, a novel method to control the pressure in the positive airway pressure (PAP) device is proposed, which, in return, reduces the need to keep the subject at high pressure throughout extended period of their sleep without hindering the efficacy of the therapy. A standard CPAP/Bi-PAP (bilevel positive airway pressure) titration study is compared and verified with the predicted pressure values. Also, the relationship and correlation between weight, age, <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$SpO_{2}$</tex-math></inline-formula>, oxygen desaturation index, and the maximum pressure required for PAP therapy are also analyzed. Thus, it is affirmed that the PAP therapy compliance can be improved by sustaining the essential pressure and avoiding extended high-pressure intervals during therapy, unless they are absolutely required.
