The last years several groups published about non-contact monitoring of vital signs (respiration, heart rate, oxygen saturation). What is the value of these techniques for current clinical practice? Introduction In recent years, there has been an increasing interest in the investigation of non contact monitoring techniques. Applied researchers have studied non contact techniques for monitoring physiological activities, such as respiration, heart rate, body pressure, body temperature and oxygen saturation. They have tried to develop and investigate these techniques due to their advantages compared with the contact monitoring techniques. Contact monitoring techniques, such as electrocardiogram (EEG) ,pulse oximeter, catheters and respiration belts, are the most existing methods of measuring the vital signs of the patients. These techniques are reliable and…show more content…
To begin with, a standard color digital camera in combination with objective lens was positioned at distance around 1 m from the neonatal. Moreover, as opposed to the previous study [],no any dedicated illumination was used in the recordings but only ambient light. Measurements, which lasted 1-5 minutes, were taken on nineteen infants with open or closed incubators. Next, videos recordings were processing by a graphical interface There are, also, further researches, which demonstrated non contact monitoring techniques for the measurement of the heart rate [], but in this study, it was decided to emphasize in the two methods, which were previously outlined. Another point that should be made is the development of the contactless monitoring for the respiration in the infants at NICU. Next, two different methods were discussed, the first one based on the real-time infrared thermography and the second one on the Laser Doppler
