Validation of a Portable Monitor for the Diagnosis of Obstructive Sleep Apnea in Morbidly Obese Patients

Abstract

Our results indicate that a simple 3-channel portable sleep monitor (ApneaLink) has a high diagnostic accuracy in diagnosing OSA in morbidly obese treatment seeking patients. Accordingly, this and similar instruments might help non-specialists to diagnose OSA in morbidly obese patients, and, importantly, help non-specialists to refer patients who need specific treatment to specialist without unnecessary delay.

Improving the diagnosis of obstructive sleep apnea in children with nocturnal oximetry-based evaluations

“…The ApneaLink is an outpatient screening device that combines pulse oximetry with oronasal airflow. This device has shown good concordance with PSG in adults [13]. However, to date there are only a limited number of studies that focused on the ApneaLink in children.…”

Practical Recommendations of the Obesity Management Task Force of the European Association for the Study of Obesity for the Post-Bariatric Surgery Medical Management

“…Polysomnography, the gold standard method to diagnose OSA, provides detailed information on sleep and respiratory and gas exchange abnormalities [50]. However, less resource-intensive and validated methods such as home-based sleep monitors may be suitable for clinical practice [54]. Snoring is the most frequent night time symptom of OSA, but it has poor predictive value because snoring without OSA is common in the general population.…”

Mandibular position and movements: Suitability for diagnosis of sleep apnoea

“…In these cases, MM‐RDI overestimated RDI compared with PSG‐RDI. This contrasts to other type 4 portable devices which underestimate RDI . This overestimation may be due to increased sensitivity of MM to detect REs, or the recording of events during wakefulness, with MM recordings failing to identify such wakefulness periods.…”
