Respiratory failure & ventilation
Regional ventilation dynamics of electrical impedance tomography validated with four-dimensional computed tomography: single-center, prospective, observational study
Authors' conclusion
Regional ventilation using electrical impedance tomography during dynamic ventilation was highly accurate and consistent with the time phase compared to four-dimensional computed tomography.
Study context
- Population
- Adults receiving passive mechanical ventilation in a general ICU, July 2021 to February 2024analysed
