Our Respiratory Physiologists
The respiratory department currently have a team of five full time respiratory physiologists working between the pulmonary function testing (PFT) and sleep laboratory. The PFT laboratory provides a range of different studies from simple spirometry to body plethysmography and exercise testing. The sleep laboratory performs sleep studies ranging from full polysomnography to overnight gas analysis (continuous overnight oximetry and transcutaneous capnography) for children.
PFTs) are a group of tests that measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body's circulation. They are usually done after the age of five years as they require co-operation with the patient to follow commands and breathing maneuvers.
These tests provide doctors with diagnostic information on a child’s lung capacity, volume and mechanics. The laboratory provides PFTs for children from many disciplines at OLCHC. Children being assessed for scoliosis surgery require PFTs to assess how their scoliosis effects their lung capacity and highlights the children who will be at higher risk during surgery.

Overnight gas analysis studies are sometimes required as part of clinical assessment pre-operatively for spinal surgery. This is a non-invasive test used to monitor a patient’s oxygen and carbon dioxide levels overnight. It gives valuable information about the patient’s ventilation status at night and is also used to monitor patients who are on non-invasive ventilation (NIV).
