Bronchial provocation (challenge) testing is the most commonly used and accepted approach for evaluating airway hyperresponsiveness (twitchy airways). A common nonspecific challenge agent used for bronchial provocation is aerosolized methacholine. In this test, the patient inhales an aerosol of one or more concentrations of methacholine. Advantage Individual dosage of the provocation material Enables precise dosing of provocation tests and reduces the risks of provocation tests. Perform inhalation provocation tests exceptionally fast and with accurate results All-in-one measurement, high automation One device for bronchial provocation tests and spiromtry tests, easy to operate Function Complete Spirometry (Slow VC, FVC, Flow-Volume Loop, Tidal breathing analysis, MVV), Bronchial dilation test pre/post dilator), Bronchial provocation test
