We offer a range of tests that are designed to measure how well your lungs work.
Each test measures a different aspect of, or action within, the lungs. Your doctor will discuss with you the tests that you need, and what is involved in them.
What types of respiratory tests are available at Cromwell Hospital?
Full Lung Function Test
This term describes a group of tests that are all used to assess different parts of the respiratory system. The tests include:
- Spirometry - which measures the rate of air flow, and estimates lung size
Diffusion Capacities - which measures how well oxygen and other gases can pass into the blood
Body Plethysmography – this is also known as the ‘box body test’. It measures lung volume, and how much effort is required for each breath
Impulse Oscillometry Test - a breathing analysis test which is suitable for paediatric patients, patients who traditionally find lung function testing difficult and immobile patients. This test involves quiet, relaxed breathing.
Respiratory Muscle Strength
A respiratory muscle strength test is often employed by a clinical if respiratory muscle weakness is suspected, such as patients with structural skeletal abnormalities, weak cough, or known neuromuscular disease.
Certain respiratory diseases can influence the amount of oxygen which can be effectively absorbed into the bloodstream via the lungs. The oxygen saturation test measures the percentage of oxygen saturation to the vascular system, normally to assess whether supplemental oxygen needs to be provided for the patient to continue normal daily activity.
Cardiopulmonary Exercise Test
This test provides a global assessment of the integrative exercise responses involving the pulmonary, cardiovascular, hematopoietic, neuropsychological, and skeletal muscle systems. It provides clinicians with relevant information to make informed decisions as to the origin of certain conditions (such as with unexplained breathlessness of no obvious cause).
Examines the physiological response to the presence of lower partial pressure of oxygen. These tests can be performed either resting (for the flying assessment) or during exercise (for the environmental stress test).
Bronchial Provocation Test - Histamine / Mannitol
This test is used to help doctors diagnose asthma and allergies. You are asked to breathe in substances that will cause your airways to narrow. This can then help your doctor to diagnose and assess your condition.
Basal Metabolic Rate Test (BMR)
This test is used to work out the number of calories your body uses when at rest, by measuring the amount of oxygen your body uses and the amount of carbon dioxide it produces. This figure is useful to dietitians for putting together weight management plans.
