Usefulness of sRtot and Rint in bronchodilator testing in the diagnosis of asthma in children.

ABSTRACT:

Introduction

The usefulness of total specific resistance (sRtot) and interrupter resistance (Rint) as a bronchodilator reversibility test (BT) alternative to forced expiratory volume in 1 s (FEV₁) in asthma diagnosis in children has not been established.

Aim

To compare different applied definitions of airflow obstruction in children measuring response to the bronchodilator by spirometry, plethysmography and the interrupter technique in asthmatic children.

Material and methods

It was a prospective, real-life, non-interventional study. Children, aged 6-18 with newly diagnosed asthma, able to perform lung function tests were included into the study. Subjects underwent a history taking, physical examination, reversibility test in spirometry, plethysmography, an
