Pilot Study for the Application of Low Power External Bioelectronic Devices in the Diagnosis of Bronchial Asthma.
Sponsor: Acurable Ltd.
Summary
The objective of this study is to detect the acoustic signals generated by the respiratory system on asthma patients using an acoustic sensor and retrospectively use these signals to identify the characteristics that differentiate patients with asthma and healthy subjects.

Conditions
Interventions
Spirometry test with bronchodilation
this test measures how much air you can breathe in and out of your lungs, as well as how easily and fast you can then blow the air out of your lungs
Methacholine challenge
test used to diagnose asthma where the patient breaths in methacholine
impulse oscillometry
test that uses sound waves to measure how much resistance there is to the normal movement of air in and out of your lungs when you are breathing at rest
Measurement of the exhaled FeNO fraction
Measure the level of nitric oxide in parts per billion (PPB) in the air the patient slowly exhales
