Pulmonology Tests provide a comprehensive assessment of the diseases of the lungs and airways. These tests are usually done to diagnose lung diseases, identify potential causes for shortness of breath, assess the effects of medications you may be taking or chemicals you may be exposed to, and measure the functioning of the lungs before a surgery.

• Six-Minute Walk Test: The test measures the impact on your body when you walk on a flat surface for 6 minutes, essentially evaluating your body’s response to exercise.
• Body Plethysmography: Body Plethysmography (or body box) is a very sensitive lung measurement used to detect lung health that might be missed with conventional pulmonary function tests. Using body plethysmography, doctors can examine the lungs’ resistance to airflow, distinguish between restrictive and obstructive lung diseases, determine the response to bronchodilators and determine bronchial hyper reactivity in response to drug (pharmacological) hyperventilation.
• Bronchodilator Reversibility: The test uses a spirometer (device to record the air inhaled and exhaled) and a bronchodilator (medical drug to dilate the bronchi and bronchioles) to diagnose whether a patient has asthma or chronic obstructive pulmonary disease (COPD).
• Lung Volumes and Transfer Factor: The test measures the ability of the lungs to transfer oxygen from the lungs to the bloodstream. Lung volume measurement permits the detection of restrictive lung disease. In this type of disease a person cannot inhale a normal volume of air. Restrictive lung disease may be caused by inflammation or scarring of the lung tissue or by abnormalities of muscles.
• Diffusion Lung Capacity (DLCO): Diffusing lung capacity helps measure the ability of your lungs to transfer oxygen from the lungs to the blood. This test is valuable for the diagnosis of patients with restrictive lung disease. It may also be used to identify the effects of certain types of drug therapies.
• Maximal Inspiratory and Expiratory Pressures (MIP/MEP): The test helps in evaluating the strength of the respiratory muscles.
• Pulse Oximetry: The test helps in monitoring a person’s oxygen level (oxygen saturation) in the blood, especially in the body parts furthest from the heart.

Spirometry: The test helps assess how well you breathe in and breathe out, by measuring the amount of air inhaled and exhaled.  The patient will be asked to breathe into a mouthpiece attached to a spirometer (recording device).
