Disclosed is a method to ergonomically improve sleep quality for continuous positive airway pressure (CPAP) device users. The system processes the user’s weight along with the apnea-hypopnea index (AHI) score collected during the phases of the sleep cycle and automatically adjusts the sleeping surface to promote optimal breathing.

Sleep Ergonomic Processing Using CPAP

With obstructive sleep disorders or sleep apnea-like conditions, deteriorating sleep quality can pose many health challenges for individuals. A method or system is needed to improve the ergonomic conditions in real time as well as to loop back and readjust the airflow during sleep.

Available breathing therapy devices such as continuous positive airway pressure (CPAP) machines are useful for generating therapeutic data; however, such devices are not capable of processing anthropometric data for re-adjustment of beds and resting furniture for sleep ergonomics without human intervention. The severity of obstructive sleep apnea (OSA) drives treatment options and is determined using the apnea-hypopnea index (AHI), which measures the number of apnea and hypopnea episodes per hour of sleep. AHI scores lower than five are normal. A patient with an AHI score of 5-15 is considered to have mild OSA, while a score of 15-30 indicates moderate OSA. AHI scores greater than 30 are indicative of severe OSA.

The novel contribution is a sleep aid or breathing therapy device, such as CPAP transmitting AHI during non-rapid eye movement (NREM), rapid eye movement (REM) sleep episodes, that allows a digitally-controlled sleep ergonomic bed to adjust/and readjust elevation degrees. The device is implemented based on an AHI (5-15) measurement.

The core novelty is in the processing of patient's weight along with the AHI collected during the phases of the sleep...
