Investigating a Wrist-sensor Oximeter to Screen for Sleep Apnoea.

2019-07-18 10:31:11 | BioPortfolio

Summary

The primary study objective is to investigate sensitivity and specificity of a wrist sensor pulse oximeter (the Oxitone Medical Oxitone 1000M device) to screen for obstructive sleep apnoea. This study will involve thirty participants attending a sleep centre suspected of suffering from obstructive sleep apnoea (case finding screening). The secondary objective is to assess patient convenience with the screening procedure.

Description

This is an observational study to assess the sensitivity and specificity of a wrist sensor pulse oximeter (Oxitone Medical Oxitone 1000M) to identify obstructive sleep apnoea cases in patients referred to the London Sleep Centre (case finding screening, or case only study). The wrist sensor pulse oximeter streams data (pulse rate, heart rate variability (HRV), blood oxygen saturation levels (SPO2), actigraphy data and skin temperature data) to a software application using bluetooth connectivity to be stored in a securely encrypted database cloud for analysis. The investigators at the sleep centre will be masked when analysing the data from the wrist sensor pulse oximeter when deciding on diagnosis of obstructive sleep apnoea. Data from the wrist sensor oximeter device will be statistically compared with the data from a conventional PPG fingertip oximeter and Peripheral Arterial Tonometry device currently in use. The study outcome will be whether the wrist sensor pulse oximeter device could be used in patients to screen reliably for obstructive sleep apnoea. The study also will include patient feedback on convenience of the screening procedure. The study will not affect routine patient medical management and care for patients assessed at the sleep centre.

Construct validity of the Patient-Rated Wrist and Hand Evaluation questionnaire (PRWHE) for nerve repair in the hand.

Many tools have been described for outcome assessment after nerve repair. The Patient-Rated Wrist and Hand Evaluation (PRWHE) have been shown to be valid for several hand conditions.

Medical and Biotech [MESH] Definitions

A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.

Machine readable patient or equipment identification device using radio frequency from 125 kHz to 5.8 Ghz.

Removal of a MEDICAL DEVICE from the market due to the identification of an intrinsic property of the device that results in a serious risk to public health.

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
