Abstract Background Gravity‐dependent positioning therapy is an established concept in the treatment of severe acute respiratory distress syndrome and improves oxygenation spontaneously breathing patients with hypoxemic failure. In coronavirus disease 2019, this seems to be less effective. Electrical impedance tomography as a point‐of‐care functional imaging modality for visualizing regional ventilation can possibly help identify who might benefit from guide those maneuvers real‐time. Therefore, prospective observational study, we aimed discover typical patterns response maneuvers. Methods Distribution 10 healthy volunteers 12 failure due 2019 was measured supine, left, right lateral positions using electrical tomography. Results showed variety patterns, which were not predictable, whereas all but one volunteer expected gravity‐dependent distribution body positions. Conclusion variable thus unpredictable 2019. add useful information on immediate reaction postural should elucidated further clinical studies. suggest customized individualized guided by
