Current Announcements

Opening of 4 new beds with private facilities, dedicated to sleep clinical research in Selma Residence at Erpent -Namur Belgium


Laboratory description

detection and analysis of the respiratory effort during sleep
by magnetometry
detection and quantification of the air flow during sleep
by sensors of hygrometry


Technical Capabilities and areas of expertise

*mandibular position and movements recorded with magnometer
*pulse transit times sampled at 1000 hz
*oro-nasal flow quantified with the changes in air hygrometry between inspiration and expiration
*grayscale mathematical morphometry apllied to respiratory signals
*new EPAP device with variable airflow resistance in development


Additional Descriptors, Keywords

sustained flow limitation , snoring , mandibular movements ,respiratory effort during overlap syndrome , respiratory effort during Cheyne Stokes breathing
