Mean (SD) lung volumes and C5 responses of normal subjects, both strapped and unstrapped, compared with patients with CFA

Unstrapped (n=9) Strapped (n=9)CFA (n=15)
FVC % predicted111 (14)63 (14)75 (14)
FEV1 % predicted123 (15)71 (15)82 (11)
RV % predicted100 (24)75 (30)75 (30)
TLC % predicted101 (16)67 (15)74 (16)
FRC (l)3.2 (1.0)2.2 (0.8)2.5 (0.9)
IC (l)3.5 (0.8)2.0 (0.6)1.9 (0.4)
  • FVC = forced vital capacity; FEV1 = forced expiratory volume in one second; RV = residual volume; TLC = total lung capacity; FRC = functional residual capacity; IC = inspiratory capacity.
