Why the study?
Polysomnography is the gold-standard for obstructive sleep apnea diagnosis but is poorly suited for long-term continuous use due to limited mobility and patient discomfort, driving demand for non-contact alternatives.
Can non-contact Doppler radar sleep monitoring technology serve as an effective alternative to polysomnography for diagnosing obstructive sleep apnea?
Can non-contact Doppler radar sleep monitoring technology serve as an effective alternative to polysomnography for diagnosing obstructive sleep apnea?
Non-contact Doppler radar sleep monitoring technology presents a promising, comfortable alternative to traditional polysomnography for long-term continuous OSA diagnosis, though further research is needed for commercialization.

Non-contact radar should not yet replace polysomnography for OSA; leaves open prospective validation to enable commercialization.
Today’s rapid growth of elderly populations and aging problems coupled with the prevalence of obstructive sleep apnea (OSA) and other health related issues have affected many aspects of society. This has led to high demands for a more robust healthcare monitoring, diagnosing and treatments facilities. In particular to Sleep Medicine, sleep has a key role to play in both physical and mental health. The quality and duration of sleep have a direct and significant impact on people’s learning, memory, metabolism, weight, safety, mood, cardio-vascular health, diseases, and immune system function. The gold-standard for OSA diagnosis is the overnight sleep monitoring system using polysomnography (PSG). However, despite the quality and reliability of the PSG system, it is not well suited for long-term continuous usage due to limited mobility as well as causing possible irritation, distress, and discomfort to patients during the monitoring process. These limitations have led to stronger demands for non-contact sleep monitoring systems. The aim of this paper is to provide a comprehensive review of the current state of non-contact Doppler radar sleep monitoring technology and provide an outline of current challenges and make recommendations on future research directions to practically realize and commercialize the technology for everyday usage.
