DIAGNOSTIC_TEST

breathing test

Spirometry is a non-invasive means of measuring lung function: The participant is asked to take a deep breath and then exhale into the sensor as hard and as long as possible. Soft nose clips may be used to prevent air escaping through the nose. If the participant does not show a definitive diagnosis of asthma, a methacholine challenge test will be performed to elicit bronchoconstriction in participants. In methacholine challenge test, the participant breaths in standardized dose of nebulized methacholine again. Methacholine challenge test is widely accepted and standardized method for assisting the diagnosis of asthma and there will be no experimental altercation in the method methacholine challenge is performed.
