We make living with apnea easier

Sleep apnea is a sleeping disorder that can lead to serious health problems, such as high blood pressure and heart trouble. Untreated sleep apnea causes breathing to stop repeatedly during sleep, causing loud snoring and daytime tiredness, even with a full night’s sleep.

Untreated sleep apnea has been shown to lead to serious health problems, such as Type II diabetes, obesity, strokes and heart failure. apnea also contributes to age-related decline in cognitive function.

Sleep apnea affects globally around 1 billion people. One of every 9  women and one of every 5 men suffer from moderate to severe OSA (Obstructive Sleep Apnea) and requires treatment. Annual size of the apnea solution market is estimated at $10B in a few years.

All existing solutions in the market are invasive which causes millions to avoid using them altogether or quit after a relatively short (and vastly uncomfortable) experience. Moreover, in recent months major CPAP manufacturers are recalling their products due to failures that may cause severe health problems.

Appscent Medical’s disruptive and innovative solution is geared to reshape the sleep solutions market by offering the world’s first non-intrusive, contactless, drugless, home use medical device for sleep apnea patients, alleviate their apnea and snoring sessions hence improve the lives of millions globally.

Appscent’s breakthrough scentific medical device offers contactless instant detection and immediate relief for sleep apnea. An AI diagnostic platform monitors the patient’s actual breathing and sleep patterns to determine the right moment to release our patented scent technology, ensuring personalized odorant solution that reduces the number of apnea events as well as their duration.

Our Unique Solution


Our disruptive innovation is a non-invasive, integrated, system that includes a detection and therapeutic platform.

The detection platform is based on remote sensing technology integrated with AI, local, and cloud based back-end. The non-contact sensors capture a range of physiological parameters which are then analyzed by our advanced AI algorithms that command the remedy platform to act based on a personalized physiological profile of the user.

  • Appscent’s breakthrough Scentific medical device offers contactless instant detection and immediate relief for sleep apnea.
  • The AI diagnostic platform monitors the patient’s actual breathing and sleep pattern.
  • Patented scent technology ensures personalized odorant solution that reduces apnea events and duration.
  • Non-contact, non-invasive, effortless and pleasant bedside solution.
  • Comfortable and easy handling, simple care and low maintenance.

How does this work?

A sensor, placed next to the sleeping patient, monitors the patient’s actual breathing and sleep patterns. When it senses that an apnea episode is about to begin, it notifies the main processing unit.


The main unit then sends back an order, and an attractive scent is dispersed above the patient’s head.


This triggers an automatic sniffing reflex, which in turn, gets the patient to start breathing normally again, without fully waking up.


This non-invasive patent protected solution is without the cost and complication of invasive surgery, and without the evident hassle which brings CPAP above 50% abandon rate in first year.


Sleep apnea is a major worldwide health problem.

Sleep apnea impacts more than 936 million people worldwide. It is a condition characterized by repetitive cessation or decreased amplitude of breathing lasting 10 seconds or more that may occur hundreds of times per night.

Sleep apnea has a significant impact on general health. Sleep apnea has been shown to contribute to the development of other conditions such as: stroke, high blood pressure, heart disease, obesity and diabetes.

Apnea can result from either a central nervous system malfunction in respiratory driving (central sleep apnea, CSA) or a peripheral malfunction of upper airway collapse despite respiratory efforts (obstructive sleep apnea, OSA). CSA and OSA can materialize independently, and they can co-occur.



The standard and most common available treatment for sleep apnea is a highly uncomfortable and invasive device known as the CPAP (continuous positive airway pressure) which is comprised of a pump and nasal mask.

The major disadvantage of the CPAP is the relatively low compliance due to its discomfort and side effects. Roughly 12% of users abandon CPAP therapy after 1 night and only 46% use CPAP on a regular daily basis. Thus, apnea remains an often untreated disorder.

( Rotenberg et al. Journal of Otolaryngology – Head and Neck Surgery (2016) 45:43  , rends in CPAP adherence over twenty years of data collection: a flattened curve )

While CPAP captures about 90% of the existing solutions in the market, there are other invasive offerings like Surgical treatments, Neurostimulation treatments, and Oral treatments, all suffering from a cumbersome procedure, invasive nature, and resistance by patients.
