Outline of Final Research Achievements	This study aimed to establish the cardiovascular and respiratory status using a non-invasive and non-contact type physiological data sensor. The physiological data sensor comprises an air cell sheet structure with air pressure sensor using pyroelectric effect equipped in measuring the heart rate and respiratory rate from small changes in the air pressure due to body movements. We assessed 50 measurements comprising 10 intraoperative measurements obtained from 5 adult patients who underwent surgery under general anesthesia. The findings revealed that both the heart rate and respiratory rate were within the clinically permissible range. We believe that ascertaining the patients’ preoperative cardiovascular status using the physiological data sensor is a useful tool for determining the need for nursing intervention and the type of nursing intervention required.
