Non-apnea electrical impedance tomography for bedside ventilation–perfusion assessment during spontaneous breathing: a prospective cross-over validation study

Conventional saline-contrast electrical impedance tomography (EIT) perfusion imaging typically requires a brief end-expiratory apnea during saline injection to reduce respiratory interference. However, this maneuver is often difficult or impractical in spontaneously breathing pat...
