In order to treat obstructive sleep apnea, Continuous Positive Airway Pressure (CPAP) devices have been developed to deliver air under constant positive pressure to the nasal passages during sleep. The goal of this project is to lay the groundwork for an in-line system of aerosol delivery through the CPAP circuit adjustable to main unit airflow and programmable for different times and durations of administration.
