Final answer:
Once someone has been diagnosed with obstructed lung function, the next step is to determine the cause of the obstruction through specific tests such as spirometry and nebulizer tests.
Step-by-step explanation:
Once someone has been diagnosed with obstructed lung function, the next step is to determine the cause of the obstruction. This can be done through different tests depending on the specific symptoms and medical history of the patient. Some tests that can be performed include spirometry, which measures the amount of air a person can forcefully exhale in one second, and a nebulizer test, which detects the rate at which air can be expelled from the lungs. These tests can help in diagnosing the specific obstructive lung disease and guide the treatment plan.
