Sleep disordered breathing service
A Sleep disordered breathing service has been established here in Naas hospital. We have the facility to carry out a multi-channel sleep study on patients referred from our outpatient clinics (no direct referrals) with symptoms suggestive of Obstructive Sleep Apnoea Syndrome.
The laboratory can carry out the following diagnostic tests:
Spirometry / Reversibility
Lung volumes via gas dilution technique and whole body plethysmography
Diffusion capacity/Transfer factor
Respiratory muscle strength measurement
Cardio-pulmonary Exercise Testing
Bronchial Challenge (Histamine)
Skin-prick allergy testing
Overnight pulse Oximetry
Multi-channel sleep studies (Limited sevice)
Hypoxic challenge test (Fitness to fly with COPD)
Instructions prior to testing
All outpatients are given timed appointments by letter.Pulmonary Function Tests (PFT’s) and Allergy testing take approximately 40 minutes and bronchial challenge or exercise testing can take up to 2.5 hours. All patients are asked to abstain from taking inhalers on the day of testing if possible. If too breathless to do so, patient should continue to take their inhalers but inform laboratory staff on arrival at appointment.
