ABSTRACT
This study was performed to investigate and study of arterial blood gases [ABG] in treated asthmatic patients with the age range of 18-74 years old in Kashan during the autumn and winter of 1999. The research was carried out descriptively on 122 referred patients [60 male and 62 female] whose diagnosis was confirmed one week after treatment with antiasthmatic drugs treatment was the same for all patients. Obtaining arterial blood samples from radial artery in sitting position and spirometry were done. The pressure of arterial oxygen value [Pa02] and the pressure of arterial C02 [PaC02] in the samples were determined and also the confidence interval was estimated. Pa02 value in treated male and female patients was 77.2 +/- 10.3 mmHg and 77.9 +/- 10.3 mmHgrespectively. The linear equation was as follows Pa02 =86.106-0.1933 xage [year]. PaC02 in treated asthmatic male and female patient was 37.7 +/- 1.96 mmHg and 37 +/- 2.61 mmHgrespectively. In treated asthmatic patients after 7 days of treatment, hypoxemia is a common complication which necessitates further supervision and monitoring after the occurrence of acute asthmatic attacks
