Background and aims: Asthma is a chronic airway inflammatory disorder that imposes substantial morbidity and mortality. Spirometry is a significant tool for the objective measurement of obstruction among asthmatics. The present study was conducted to assess the pulmonary function test parameters among asthmatics and compare the observed and predicted values.
Materials and methods: This cross-sectional research was performed on 120 asthmatic patients who attended a tertiary care healthcare center and underwent spirometry evaluation. The spirometry indices such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, peak expiratory flow rate (PEFR), and maximal voluntary ventilation (MVV) were recorded. Further, a gender-wise comparison of spirometry indices was also done.
Results: There was a substantial decrease in FVC (2.05 ± 0.12 vs. 2.75 ± 0.24 L/sec; p = 0.02), FEV1 (1.78 ± 0.16 vs. 2.38 ± 0.32 L/sec; p = 0.01), FEV1/FVC ratio (74 ± 4.38 vs. 83 ± 5.76 %; p = 0.01), PEFR (4.76 ± 0.42 vs. 5.82 ± 0.65 L/sec; p = 0.03), and MVV (78.65 ± 28.45 vs. 115.87 ± 32.15 L/min; p = 0.001) for observed and predicted values. Female asthmatic patients displayed a substantial decline in FVC (p = 0.001), FEV1 (p = 0.006), FEV1/FVC (p = 0.001), and MVV (p = 0.01) when compared to males.
Conclusion: This study suggests that asthmatic individuals had impaired lung function upon initial assessment. Female asthmatic patients studied are at increased risk of asthma severity when compared to males.
