Clinico Etiological Evaluation of Asthma with Special Reference to Pulmonary Function Test

Objective: 1) To Study incidence and analyse demographic profile of Asthma. 2) To Analyse role of Pulmonary Function Test in diagnosis and control of Asthma and observe role of serial monitoring of pulmonary function tests in relation to effect of preventive drug regimen. Design: This Prospective Observational type of study was conducted at the Paediatric Department of Civil hospital, Ahmedabad on Patients Diagnosed with Asthma from 15/07/2022. Subjects/Patients: Patients aged between 1 to 12 years were included. Methods: Statistical analysis used: chi square test, p value. Results: In present study, 89.5% had onset of asthma symptoms between 1 to 5 year of age, 2.01% had symptoms onset <1 year of age and 8.4% had onset >5 year of age. Pulmonary function test is not much affected in well controlled disease but in persistent variety there are restrictive changes in pulmonary function test in form of decrease in % of FEV1 predicted. Conclusion: In Pulmonary function testing value of FEV1 and FVC: FEV1 correlate with severity of Asthma which suggests that spirometry not only helps in diagnosis but also helps in assessing the severity which has the key role in the successful management.
