Noninvasive breathing pattern monitoring in patients with bronchial asthma
Abstract
Impedance pneumography (IP) system for breathing pattern monitoring was developed. IP system was calibrated volumetrically using integrated pneumotachigraphy. We studied mean breathing pattern parameters in 39 healthy subjects, patients with mild (n=39), moderate (n=25) and severe (n=17) bronchial asthma (BA) in sitting posture during 10 min. interval. Mean breathing rate was significantly (p<0.05) higher in all BA groups (18.0±0.6, 18.0±0.6, 20.4±1.2 /min., M±m) than in controls (16,2±0,6 /min.). Patients with severe BA demonstrated significantly higher mean partial expiratory time (58.2±0.8%) and lower mean tidal volume (0.35±0.04 I) than healthy subjects (55.8±0.5% and 0.47±0.02 I, respectively). We concluded that developed noninvasive breathing pattern monitoring method is informative in patients with BA.
