Abstract :
[en] Studied breathing patterns and hyperventilation symptoms in 80 adolescents and adults (aged 16-60 yrs) with mild to moderate asthma and 40 adolescents and adults (aged 16-60 yrs) with no asthma symptoms (healthy controls). Data on pulmonary function, ventilation and breathing pattern, and psychological symptoms were obtained by clinical observation and questionnaire. Asthmatic Ss were requested not to take bronchodilatation medications for 24-48 hrs prior to testing. The Anxiety Sensitivity Index-Revised (S. Taylor and Cox, 1998), the Self-Consciousness Scale-Revised (A. Fenigwstein et al, 1975), the State-Train Anxiety Inventory, the Nijmegen Questionnaire (P. van Doorn et al, 1982), the Sense of Coherence Scale (A. Antonovsky, 1987), the Positive and Negative Affect Schedule (D. Watson et al, 1988), the Beck Depression Inventory, and the Asthma Symptoms Checklist (R. A. Kinsman et al, 1973, revision by Brooks et al, 1989) were used. The results show that the asthmatic subjects have lower PetCO2 than normal subjects and that variables associated with lower PetCO2 include total volume, female gender, and negative affectivity. The results also show that female subjects and asthmatics have similar breathing patterns and compared to male subjects
