From: Response to PEEP in COVID-19 ARDS patients with and without extracorporeal membrane oxygenation. A multicenter case–control computed tomography study

Fig. 1

CT images acquired at the mid-chest level in 4 representative patients. ECMO patients are presented in the uppermost quadrants, while non-ECMO patients are presented in the lowermost quadrants. Patients with ∆PEEP5–15-induced recruitment below the median value of the whole population (deemed as low recruiters) are presented in the leftmost quadrants, while patients with PEEP5–15-induced recruitment above the median value of the whole population (deemed as high recruiters) are presented in the rightmost quadrants. In each quadrant, the upper two images were acquired at PEEP 5 cmH2O (one raw CT image on the left and one quantitative parametric CT on the right), and the lower two were acquired at PEEP 15 cmH2O. The color code used for parametric images is provided in the figure legend. CT, computed tomography, ∆PEEP5–15-induced recruitment, amount of recruitable lung between PEEP 5 and 15 cmH2O, ECMO, extracorporeal membrane oxygenation, PEEP, positive end-expiratory pressure
