A CPAP (continuous positive airway pressure) machine pressurizes the airway to reduce obstruction in a patient’s air passage​. Obstructive sleep apnea (OSA) diagnoses have been rising around the world due to an ageing population, increased obesity levels, and worsening environmental conditions. OSA is a sleep disorder caused by a blocked airway and can lead to daytime drowsiness and poor quality of life. Left untreated, OSA may incite additional health problems such as stroke and heart failure.​

​A continuous positive air pressure (CPAP) device prescribed by a doctor can alleviate OSA conditions. A CPAP device prevents airway obstructions during sleep by forcing air into the lungs to keep the air passage open. This device helps maintain positive air pressure in order to prevent a patient’s tongue or soft palate from blocking air flow into the back of the throat. High-end CPAP devices utilize pressure sensors to control the prescribed pressure settings that are generated by the blower. Snoring detection is an additional advantage of integrating a pressure sensor.​
