Consistent vital sign monitoring is critically important for early detection of clinical deterioration of patients in hospital\nsettings. Mostly, nurses routinely measure and document the primary vital signs of all patients 2ââ?¬Â3 times daily to assess\ntheir condition. To reduce nurse workload and thereby improve quality of patient care, a smart vital sign monitor\nnamed ââ?¬Å?Vitalââ?¬ÂSCOPEââ?¬Â for simultaneous measurement of vital signs was developed. Vital-SCOPE consists of multiple\nsensors, including a reflective photo sensor, thermopile, and medical radar, to be used in simultaneous pulse rate,\nrespiratory rate, and body temperature monitoring within 10 s. It was tested in laboratory and hospital settings. Bland-Altman\nand Pearsonââ?¬â?¢s correlation analyses were used to compare the Vital-SCOPE results to those of reference measurements.\nThe mean difference of the respiratory rate between respiratory effort belt and Vital-SCOPE was 0.47 breaths per minute\nwith the 95% limit of agreement ranging from âË?â??7.4 to 6.5 breaths per minute. The Pearsonââ?¬â?¢s correlation coefficient was\n0.63 (P < 0 05). Moreover, the mean difference of the pulse rate between electrocardiogram and Vital-SCOPE was 3.4\nbeats per minute with the 95% limit of agreement ranging from âË?â??13 to 5.8 beats per minute; the Pearsonââ?¬â?¢s correlation\ncoefficient was 0.91 (P < 0 01), indicating strong linear relationship.
