Cardiorespiratory Response Model for Pain and Stress Detection during Endoscopic Sinus Surgery under Local Anesthesia

摘要

The effect of surgical procedure on breathing movement and the effect of characteristics of breathing movement on changes in heart rate and blood pressure during actual endoscopic nasal surgery were analyzed using analysis of variance and Bayesian network modeling. As the result, the probabilistic causal relationship between respiratory irregularities, increasing blood pressure and patients' complaint of pain Was found. This result is expected to be used as patient pain and stress detection method without discomfort during actual surgery under local anesthesia.
