Introduction

Forced oscillation technique (FOT) and spirometry are used for diagnosis and monitoring of lung diseases. To improve methods understanding of test experiences of patients are important as it requires patient?s cooperation.

Aims and Objective

We  aimed to compare patient experiences between FOT and Spirometry.

Methods

Subjects underwent FOT by Antlia device followed by Spirometry using Cosmed device. Demographic details and responses of patient graded in Likert scale against a predefined questionnaire for FOT and spirometry were recorded.

Results

Lung function test experiences of 98 patients aged between 22-85 were compared across 8 questions. Statistically significant difference between FOT and Spirometry test experiences (Z=-4.67, p=<0.01) was found. Median experience score was higher for FOT (3.5) compared to Spirometry (3.37). Comparative differences in experiences are depicted across individual questions in Table 1. The experience of breathing, coughing, shortness of breath during test appeared significantly positive on FOT in comparison to Spirometry. 

Conclusion

Subjects reported more comfort with FOT than spirometry while doing lung function test.
