Development of a baby friendly non-contact method for measuring vital signs: First results of clinical measurements in an open incubator at a neonatal intensive care unit

摘要: For infants and neonates in an incubator vital signs, such as heart rate, breathing, skin temperature blood oxygen saturation are measured by sensors electrodes sticking to the skin. This can damage vulnerable of cause infections. In addition, wires interfere with care hinder parents holding touching baby. These problems initiated search for baby friendly 'non-contact' measurement signs. Using a sensitive color video camera specially developed software, rate was derived from subtle repetitive changes. Potentially also respiration could be obtained. A thermal used monitor distribution whole body detect small variations around nose revealing rate. After testing laboratory, seven babies were monitored (with parental consent) neonatal intensive unit (NICU) simultaneously regular monitoring equipment. From recordings accurate rates images provided rates. To correct movements baby, tracking software applied. At present, image processing performed off-line. narrow band light sources non-contact measured. Non-contact signs has proven feasible into real time system. Besides application on NICU function large potential other patient groups.
