AB  - RationaleAlthough polysomnography is an important diagnostic tool for sleep medicine, it is an uncomfortable and costly procedure. In order to reduce this burden, multiple low-level home monitoring systems have been developed. In this study we want to clinically evaluate some of these new, less obtrusive sensors.ObjectiveTo compare breathing pattern and heart function measured by new sensors with gold standard.Methods14 patients (mean age 65±18 y) with respiratory problems are included in this trial for a one-night measurement. A new movement sensor (Sensotiss), a light cable embedded in the mattress, measures the breathing pattern by detecting changes in optical reflection. Heart function is measured by a wireless electrocardiogram (ECG) body patch with Bluetooth connection. As gold standard, end-tidal capnography (Respironics) and 1 lead standard ECG (GI-MAC5500) are chosen.ResultsECG and breathing pattern compared with gold standard are shown in figure 1.ConclusionPreliminary results show that the new ECG sensor is reliable with respect to the golden standard. Breathing pattern derived from the sensor in the mattress looks promising, but requires a thorough understanding for comparison with capnography. In the future, computerized algorithms based on these new signals could be of great clinical value for both screening and diagnostic purposes.ICON project NXT_SLEEP is funded by iMinds.
