Obstructive Sleep Apnea (OSA) syndrome is a disorder characterized by repetitive episodes of upper airway obstruction that occur during sleep. OSA lead to desaturation and often lead to an arousal.~Associated features include loud snoring and fragmented non-refreshing sleep and have profound impact on quality of life, on safety on the roads and at work, and on the cardiovascular and metabolic systems.~The standard treatment for apnea remains a device consisting of a pump and nasal mask that provide continuous positive airway pressure (CPAP). CPAP acts as a pneumatic splint that elevates and maintains a constant pressure along the upper airway during inspiration and expiration that prevents airway collapse. The major disadvantage of CPAP is the relatively low compliance.~Appscent developed a non-contact effortless bedside solution based on the following: odors modify respiratory patterns during wake . Mildly trigeminal and pure olfactory odorants do not arouse or wake. Odorants transiently presented during sleep induced a respiratory rejection type response, this suggests that manipulating the respiratory system without waking is viable .
