About

Many connected objects available over-the-counter to the general public claim to measure physical quantities that may have a medical application. Examples include heart rate, oxygen saturation, respiratory rate, blood pressure, body composition between body fat, lean mass and bone mass, and motion analysis. .

The continuous collection of these quantities by a cheap and easily accessible device opens important medical perspectives in the areas of home monitoring of chronic diseases or preventive medicine in general. Nevertheless, the medical decisions that could be made on the basis of the information provided by these objects require that the measurement be reliable, which is not always the case.

The evaluation of the accuracy of measurements made by these objects therefore seems to be a prerequisite for future use in a medical context. This study therefore proposes to test the adequacy between "gold-standard" measurements carried out in consultation in the department of functional explorations of the Bichat Claude-Bernard hospital and the measurements of the same parameters by connected objects, under the conditions of intended uses by their manufacturer.

Full description

Primary objective : Evaluate, in patients consulting for polysomnography, respiratory functional explorations or osteodensitometry, or as part of a day hospital cardiology. The accuracy of the measurement provided by a connected object in relation to the "gold standard" measurement made during the visit. The parameters studied will be:

• For polysomnography, pulse oxygen saturation (SpO2), heart rate (HR) and respiratory rate (RF), sleep quality (efficacy, duration of mild slow sleep, deep slow sleep and REM sleep)
• For bone densitometry, body composition in lean mass, fat mass and bone mass, weight • For respiratory function tests, pulse oxygen saturation (SpO2) and heart rate (HR)
• For day hospitalization in cardiology, blood pressure (BP), heart rate (HR) and heart rate, existence of rhythm disorders or conduction

Secondary objectives:

• Evaluate the ease of use of the device (evaluated by an ad-hoc questionnaire completed by the nursing staff)
• Describe the temporal evolution of the recorded parameters (excluding osteodensitometry for which the measurement is unique)
• For day hospitalization in cardiology, evaluate the diagnostic performance of objects tested on the existence of cardiac rhythm disorders (sinus bradycardia, sinus tachycardia, atrial fibrillation, presence of extrasystoles) or conduction disorders (atrioventricular block). -ventricular, branch block)

Enrollment: 400 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
