COPD test
This pulmonary function test measures how much air is inhaled and exhaled, focusing on airflow limitation.
What is Spirometry?
This simple handheld device measures how fast a person can push air out of their lungs when they blow out hard and fast.
What is a Peak Expiratory Flow (PEF) meter?
This test screens for a genetic condition that can lead to early-onset COPD in non-smokers.
What is the Alpha-1 Antitrypsin Deficiency Test?
In COPD, this ratio is reduced to less than 70%, indicating irreversible airway obstruction.
What is the FEV1/FVC ratio?
These tests can identify specific allergens that may trigger asthma, using either skin or blood samples.
What is Allergy Testing?
This test assesses how well the lungs function during physical activities in both COPD and asthma patients.
What is an Exercise Tolerance Test?
This imaging test shows hyperinflation of the lungs and a flattened diaphragm in patients with COPD.
What is a Chest X-ray?
This challenge test involves inhaling substances like methacholine to trigger asthma symptoms.
What are Bronchial Provocation Tests?
The Arterial Blood Gas (ABG) Test will result in these O2, CO2, and pH levels in COPD patients
What is Hypoxemia, Hypercapnia, Respiratory acidosis?
This test measures the diffusing capacity of the lungs by inhaling a gas mixture and measuring the concentration of carbon monoxide in exhaled air.
What is the DLCO test?
This test measures inflammation in the airways by analyzing levels of a specific gas in exhaled air.
What is Fractional Exhaled Nitric Oxide (FeNO)?
This test measures levels of oxygen and carbon dioxide in the blood to determine the severity of respiratory failure in COPD patients.
What is an Arterial Blood Gas (ABG) test?
This parameter measures the volume of air that can be forcibly exhaled in one second.
What is FEV1?
This type of imaging test can help evaluate structural changes in the lungs in asthma patients.
What is a CT Scan?
This sign may be observed on X-ray due to increased air trapping in COPD.
What is hyperlucency?
