The use of electrical impedance tomography for individualized ventilation strategy in COVID-19: a case report

BMC Pulm Med. 2021 Jan 22;21(1):38. doi: 10.1186/s12890-021-01411-y.

Abstract

Background: Clinical management of COVID-19 requires close monitoring of lung function. While computed tomography (CT) offers ideal way to identify the phenotypes, it cannot monitor the patient response to therapeutic interventions. We present a case of ventilation management for a COVID-19 patient where electrical impedance tomography (EIT) was used to personalize care.

Case presentation: The patient developed acute respiratory distress syndrome, required invasive mechanical ventilation, and was subsequently weaned. EIT was used multiple times: to titrate the positive end-expiratory pressure, understand the influence of body position, and guide the support levels during weaning and after extubation. We show how EIT provides bedside monitoring of the patient´s response to various therapeutic interventions and helps guide treatments.

Conclusion: EIT provides unique information that may help the ventilation management in the pandemic of COVID-19.
