Monitoring the asthmatic patients: Role of the mini peak flow meter

ABSTRACT

31 patients with bronchial asthma were submitted to the study from October, 1988 to April, 1990. 21 patients were using mini peak meters in monitoring their condition [G 1]. 10 asthmatic patients were used as control [not using mini peak flow meters]. Statistical analysis of all patients ventilatory functions before and after solbutamol inhalation showed a highly significant change which means reversibility of airways obstruction. In G 1 patients, there was a good correlation between chest symptoms [wheeze, dyspnea and cough] and PEFR measurements. PEFR records of the patients helped to define the possible precipitating factors for their asthmatic attacks, 9 cases [42.85%] respiratory tract infections, 4 cases [19.04%] dust and smoke, 1 case [4.76%] insecticide spray and another one due to volatile oils and 6 cases [28.57%] remained unknown. PEFR monitoring in G 1 has a significant effect [P <0.01] on decreasing the number of visits to the doctor and a highly significant effect [P <0.005] on decreasing the number of severe attack. So, regular objective observation of some aspects [PEFK] of respiratory functions is just as necessary in the management of asthma as regular blood sugars are in the management of diabetes
