3.3. Lung Mechanics
Figure 2 shows the lung mechanics parameters analyzed (Z5Hz, X5Hz, R5Hz,
R20Hz, R5Hz-R20Hz) comparing non-asthmatic with asthmatic children.
Asthmatic children showed impaired impedance of respiratory systems
(Z5Hz; p<0.02), respiratory reactance (X5Hz;
p<0.002); proximal airways resistance (R20Hz;
p<0.02), total resistance of respiratory system (R5Hz;
p<0.009) and resistance of peripheral/distal airways
(R5Hz-R20Hz; p<0.01).
