Sleep apnea pre-screening on neonates and children with shoe integrated sensors

The aim of this paper is to provide a high level architectural description of portable sleep apnea screening system. Proposed patient mobile monitoring solution increases their mobility, flexibility and measures vital data with minimal patient disturbance with increased reliability. Data is acquired with synchronous dual multi-wavelength optical sensors, placed on the foot. Movement artefacts are reduced with the correlation of accelerometer readings. Results are sent over the wireless link to the smartphone for further diagnosis which gives also feedback to the end user. Because of the limitation of the measuring device dimensions and computational power some of the signal processing is done on the smartphone. Combining different latest technology achievements makes our proposed solution suitable for neonates and children for sleep apnea pre-screening.
