Does your patient suffer from any of the following?

·   New or severe breathlessness?

·   Frequent chest infections?

·   Persistent cough or an unchanged cough?

·   Experience chest pain, unexplained fatigue or sudden weight loss?


Would your patient benefit from any of the following?

·   Assessment of smoking patients/respiratory status preoperatively?

·   Skin prick allergen testing for atopic disease?              

·   Measurement of Exhaled Nitric Oxide to determine the benefit of ICS treatment?






What does it involve?






There are a number of tests that we perform here in the laboratory. The following is a guide on which test would benefit your patients.




Flow Volume Loop 

Pre & Post bronchodilator







First presentation sleep patient

Full Lung Function

(aka Complex Lung Function) Includes Pre & Post bronchodilator Flow volume loops, Lung Volumes and Gas Transfer.

First presentation respiratory patient


Smoker/Ex-smoker new shortness of breath

Emphysema for valve insertion (EBV)

Interstitial Lung Disease

Pulmonary Fibrosis

Medico-Legal / Work Cover assessments

Patient is on Prednisolone

On or about to commence chemotherapy/Stem Cell Transplant.

Occupational exposure to harmful substance

Bird Fanciers Lung - Hypersensitivity pneumonitis

Pulmonary Arterial Hypertension




Bronchial Provocation –






Normal CLF but patient has asthmatic symptoms

Defence/Police Force Recruitment



Bronchial Provocation - Hypertonic Saline Challenge





SCUBA Diving medicals



Respiratory Muscle Strength - MIPs MEPs





Motor Neuron Disease, Muscular Dystrophy, Guillain–Barré syndrome



6 Minute Walk Test





Evaluate for home oxygen (MASS)

Pulmonary Arterial Hypertension



Cardiopulmonary Exercise Test



Determination of the exercise capacity

Determination of the cause of a cardiopulmonary limitation to exercise

Identification of abnormal cardiopulmonary responses to exercise

Exercise prescription and monitoring response to exercise for training and rehabilitation

Evaluation of results of therapeutic intervention

Pre-operative evaluation

Impairment/disability evaluation




Allergen Skin Prick Test




Quantify atopy


Differentiate between allergic and vasomotor rhinitis

Food reactions


Hypoxic Altitude Simulation Test



Patients wishing to fly by commercial airliner likely to develop PaO2 <55mmHg under in-flight conditions (COPD, other lung disease or cardiovascular disease resulting in PaO2 <72mmHg under sea-level, room air conditions)

Pre-existing requirements for oxygen

Other subjects with medical conditions at risk may include:

•             Obstructive sleep apnoea

•             Parenchymal lung disease 

•             PaO2 of 60-70 mmHg
