Respiratory monitoring using wearable EIT in emergency medicine

Abstract

Electrical Impedance Tomography (EIT) is a technique to perform dynamic lung tomography by measuring the electrical impedance. Recently, EIT has been applied in clinical settings, and its usefulness in confirmation of treatment for Acute Respiratory Distress Syndrome (ARDS) and titration of mechanical ventilator setting has been revealed. However, there are no EIT machines commercially available in Japan and also currently available machines have limitations in using in emergency situation and longer use. We are currently developing a machine that is small sized wearable and can be used for a longer period. We would like to discuss the possibility of clinical use especially in emergency and critical care field by showing some cases.
