Bronchoprovocation challenge testing

Also known as: Inhalation challenge tests

Inhalation challenge tests are done to measure the response of your airways to substances that may be causing asthma or wheezing. These tests are also called provocation studies.

During inhalation testing, increasing amounts of a substance are inhaled through a nebulizer, a device that uses a face mask or mouthpiece to deliver the substance in a fine mist (aerosol). Sometimes, increasing amounts of a histamine or methacholine may be inhaled through the nebulizer. Spirometry readings are taken to evaluate lung function before, during and after inhaling the substance.

Providence Pulmonary and Critical Care Medicine provides inpatient and outpatient consultation, evaluation and state-of-the-art treatment for a wide range of acute and chronic lung diseases and critical illnesses.
