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).
