The use of portable monitoring for sleep apnea diagnosis in adults

Abstract

Due to increasing demand for sleep services, there has been growing interest in ambulatory models of care for patients with obstructive sleep apnea (OSA). The implementation of alternative approaches to the current management by full polysomnography (PSG) in the sleep laboratory is necessary for diagnosing this syndrome due to the high cost of full-night PSG. A good alternative option for OSA diagnosis is portable monitoring (PM), which is known for its accuracy, ease of management and lower cost when compared with full PSG. PM has not been well validated for OSA diagnosis in patients with medical comorbidities or in elderly individuals and children. PM may be recommended as an alternative method to PSG for patients with high clinical risk for OSA. In the present review, we describe the use of PM for OSA diagnosis and evaluate the current progress, costs, limitations and applications of these devices in various groups of patients, particularly for patients with comorbid diseases.

Diagnostic accuracy of nasal cannula versus microphone for detection of snoring

“…These studies require an expert technician, which makes the procedure costly and time‐consuming. Home sleep‐apnea testing (HSAT) systems use a simplified mechanism to diagnose respiratory sleep disorders, lowering overall costs and wait times …”

“…Home sleep-apnea testing (HSAT) systems use a simplified mechanism to diagnose respiratory sleep disorders, lowering overall costs and wait times. [11][12][13][14][15] Our study aims to compare the commonly available in-home cannula with microphone-based HSAT tests to determine its analytical results and measurement of snoring severity; these two tools were chosen for their accessibility and widespread use in clinical practice. To date, there only has been a single report that has compared the three devices discussed by the AASM (i.e., nasal cannula, microphone, and piezoelectric sensor) using a few patients, but that report was based on individual snore events, expanding the sample satisfactorily.…”

Low‐Cost Photoelectric Flow Rate Sensors Based on a Flexible Planar Curved Beam Structure for Clinical Treatments

“…However, accurately measuring and assisting with breathing poses challenges due to the complexity of human respiration. [42][43][44] To overcome these challenges, flow rate sensors have been proposed as a potential solution. Figure 3f demonstrates how flow rate sensors can assist ventilators in detecting human respiration.…”

Validation of a sheet-shaped body vibrometer for screening of obstructive sleep apnea

“…Hence, it is believed 82% of men and 93% of women with moderate-tosevere OSA remain undiagnosed (8). Therefore, there is a need for a convenient and ambulatory portable monitor (PM) with a high screening accuracy for OSA that facilitates a reduced time to diagnosis (9,10).…”

“…Previous studies on the validity of OSA screening with non-wear PM devices, such as a static charge sensitive bed (SCSB) (13,14) and a sheet-shaped device placed on a mattress (15)(16)(17), have been conducted. However, due to the insufficient number of validation studies, these devices have been classified as type 4 PM for the screening of OSA, and have hence not been generally accepted (9,11).…”
