Role Of Spacer Device In Improving FEV1 And PEFR In Asthmatic Patients

Abstract

Objective: To study the role of spacer device in improving FEV1 and PEFR in asthmatic
patients.
Material & Methods: In this quasi experimental study, fifty asthmatics patients, already on
inhaled therapy, visiting outpatient department of Jinnah Hospital Lahore were included.
Results: While assessing the improvement, the mean FEV1 (mean±SD) was 1.46±0.42 litres,
1.97±0.76 litres, and 2.32±0.39 litres at first, second and third visits respectively. The
improvement in FEV1 was found to be significant after the use of spacer device (p < 0.001). The
mean PEFR (mean ±SD) was 163.34±58.56 L/min, 271.68±69.12 L/min, and 346.66±64.15
L/min at first, second and third visits respectively. The improvement in PEFR at second and third
visits as compared to first visit was statistically significant (p = 0.001).
Conclusion: FEV1 & PEFR significantly improve after the use of spacer device
