BackgroundMonitoring of vital parameters is an important topic in neonatal daily care. Progress in computational intelligence and medical sensors has facilitated the development of smart bedside monitors that can integrate multiple parameters into a single monitoring system. This paper describes non-contact monitoring of neonatal vital signals based on infrared thermography as a new biomedical engineering application. One signal of clinical interest is the spontaneous respiration rate of the neonate. It will be shown that the respiration rate of neonates can be monitored based on analysis of the anterior naris (nostrils) temperature profile associated with the inspiration and expiration phases successively.ObjectiveThe aim of this study is to develop and investigate a new non-contact respiration monitoring modality for neonatal intensive care unit (NICU) using infrared thermography imaging. This development includes subsequent image processing (region of interest (ROI) detection) and optimization. Moreover, it includes further optimization of this non-contact respiration monitoring to be considered as physiological measurement inside NICU wards.ResultsContinuous wavelet transformation based on Debauches wavelet function was applied to detect the breathing signal within an image stream. Respiration was successfully monitored based on a 0.3°C to 0.5°C temperature difference between the inspiration and expiration phases.ConclusionsAlthough this method has been applied to adults before, this is the first time it was used in a newborn infant population inside the neonatal intensive care unit (NICU). The promising results suggest to include this technology into advanced NICU monitors.

Via IRT, it is possible to detect fluctuations in temperature of premature infants. The cooling in I2 after SSC should be taken into account before routine daily care.

For critically ill preterm infants, there is a clinical need for contact-free monitoring technologies, which would eliminate discomfort and potential harm (e.g., necrosis) due to adhesive electrodes, temperature and saturation sensors. Hence, this chapter focuses on non-contact physiological monitoring of infants based on infrared (IR) thermography. This technique has the potential to replace the conventional temperature sensing by detecting radiated thermal energy emitted from the baby’s surface according to black-body radiation principle. This allows the application of a less invasive method giving more detailed information about the thermoregulation status of newborn infants. As an illustrative example, an investigation into thermoregulation physiology during kangaroo care method has been chosen to illustrate the benefit of this method for standardized neonatal intensive care unit (NICU) procedures. Furthermore, this technique may have a large impact on non-contact respiratory monitoring, as it allows quantitative evaluation of the heat transfer processes over nostrils region. Moreover, the ability to detect infrared respiration (IRTR) signature with thermography imaging, will pave the road toward a non-contact breathing monitoring. This in turn will influence the development efforts for wireless and smart incubator solutions.
