Example of EIT images during forced expiration maneuver (∆FEV1EIT) in two representative patients. Dynamic image of expired volume at 1 second during forced expiration (∆FEV1EIT) in two representative patients; 2A, asymptomatic patients (mMRC = 0); panel 2B: Symptomatic patient (mMRC = 2). Negative values represent the regional loss of volume (AU) in the 1st second after the start of forced expiration from vital capacity (FEV1)
