Abstract:
A retrospective study was conducted on a sample of 77 subjects to assess the interest of computerized flowmeter "one-flow" in the diagnosis and follow up of asthma. 77 patients and a control group matched for age and sex, measured four times by day, the forced expiratory volume in one second as well as the peak expiratory flow during 15 to 30 days. The monitoring of these two variables allowed to participate to the exclusion from the study of fifteen patients whose asthma diagnosis was informed. It also allowed the confirmation of four occupational asthma. Concerning the adherence of the treatment by patients, the conclusion of the study showed that 47% of patients modified their treatment at home without consulting their doctors, 38% resorted to their doctor and only 3% resorted to the emergencies.
