Table of Contents


Sleep disordered breathing encompasses a range of conditions that disrupt normal breathing patterns during sleep, with obstructive sleep apnea being one of the most studied. Precise diagnosis and research into these conditions hinge on detailed and accurate data collection, traditionally obtained through Polysomnography (PSG).

However, the complexity and cumbersome nature of PSG setups pose significant challenges, particularly for studies conducted in home settings. This has led to a demand for simpler, yet equally accurate, methods of data collection.


Enter Fibion Vitals, an innovative wearable device designed to streamline sleep disordered breathing research without sacrificing data quality. In contrast to the intricate and often uncomfortable setup required by PSG, Fibion Vitals offers an easy-to-use, participant-friendly solution that captures a wide range of vital physiological signals relevant to sleep disorders.

“Fibion Vitals blends sleep lab depth with wearable ease, making measurements of sleep-disordered breathing easier even at home.”

This article dives into the features and advantages of Fibion Vitals compared to traditional PSG, emphasizing its potential to transform sleep disordered breathing studies with its simplicity and precision.

Understanding Sleep Disordered Breathing

Sleep disordered breathing (SDB) represents a spectrum of conditions that impair respiratory patterns during sleep, the most common of which is obstructive sleep apnea (OSA). These conditions are characterized by repeated interruptions in breathing due to the partial or complete obstruction of the airway, leading to fragmented sleep and decreased oxygen saturation. The implications of untreated SDB range from daytime fatigue and cognitive impairment to more serious cardiovascular risks.

The Importance of Accurate Diagnosis

Accurate diagnosis and study of SDB are paramount for developing effective treatment plans and understanding the broader health implications of these conditions. Traditional diagnostic methods, such as Polysomnography (PSG), while considered the gold standard, involve complex setups including multiple sensors and wires that can disrupt natural sleep patterns, potentially skewing data accuracy. Moreover, the technical expertise required for PSG setup and data analysis limits its applicability in home-based studies, where simplicity and patient comfort are key.

The Limitations of PSG in Sleep Disordered Breathing Studies

Polysomnography (PSG) has long been the cornerstone of sleep disorder diagnosis, including sleep-disordered breathing. It offers a comprehensive array of data through various sensors that measure brain waves, oxygen levels in the blood, heart rate, breathing, as well as eye and leg movements. Despite its thoroughness, PSG comes with notable limitations, especially when deployed for home-based studies.

Complexity and Comfort: The complexity of the PSG setup, which often requires professional assistance, poses a significant barrier. The array of wires and sensors can be intrusive, potentially altering the natural sleep behavior of participants. This complexity extends to the data analysis phase, demanding specialized knowledge to interpret the results accurately.

Accessibility and Practicality: Conducting PSG studies outside a sleep laboratory is challenging. The equipment is not only expensive but also less accessible for widespread home-based studies. This limitation restricts the scalability of research, particularly studies aiming to gather longitudinal data across diverse populations.

Emerging Technologies in SDB Research

The limitations of PSG have prompted researchers to explore alternative methods for studying SDB in more naturalistic settings. Wearable technologies, capable of monitoring a range of physiological signals without intruding on the participant’s normal sleep routine, have emerged as promising tools in this domain.

Among these, Fibion Vitals stands out for its comprehensive data collection capabilities, ease of use, and non-intrusive design, offering a viable alternative to traditional PSG for studying sleep disordered breathing in home settings.
