The Clinical Application of Electrical Impedance Tomography in Clinically Ill Patients: a Cross-sectional Study

The application of electrical impedance tomography (EIT) in intensive care is increasing. It can provide additional information on individual respiratory physiology of patients, enabling clinicians or respiratory therapists to monitor patients' respiratory responses to different ventilator settings, respiratory treatment methods or clinical evolution, and thus achieve more personalized mechanical ventilation methods. Although this technology provides a large amount of valuable information, there is still uncertainty about how to use it and interpret the results in critically ill patients. Therefore, the evidence that EIT-guided ventilation strategies can improve prognosis is still in its infancy. Through this survey, the investigators aim to understand the current experiences and guiding roles of EIT in clinical practice. The secondary objective is to learn about the current challenges of EIT in clinical and practical settings, as well as the factors that promote or hinder the implementation of EIT monitoring technology.
