Comprehensive Respiratory Assessment
Lung function testing, or spirometry, measures how well your lungs work by assessing the volume of air you can inhale and exhale, and how quickly you can expel air. These measurements provide essential information for diagnosing and monitoring respiratory conditions.
The Testing Process
You’ll breathe through a mouthpiece connected to a spirometer whilst performing various breathing manoeuvres. The test involves taking deep breaths and forcefully exhaling, as well as breathing normally. The entire assessment typically takes 15-20 minutes and requires no sedation or invasive procedures.
Clinical Applications
Lung function testing evaluates:
– Unexplained breathlessness or chronic cough
– Asthma diagnosis and management
– Chronic obstructive pulmonary disease (COPD)
– Pre-operative assessment for major surgery
– Occupational lung disease screening
– Response to respiratory medications
– Monitoring chronic respiratory conditions
Understanding Your Results
The test measures several key parameters:
– Forced vital capacity (FVC): Total air you can forcefully exhale
– Forced expiratory volume (FEV1): Air expelled in the first second
– Peak expiratory flow: Maximum speed of exhalation
– FEV1/FVC ratio: Indicates obstructive or restrictive patterns
Integrated Gastroenterology Assessment
Whilst primarily a respiratory test, lung function assessment proves valuable in gastroenterology for evaluating patients with gastro-oesophageal reflux-related respiratory symptoms, assessing surgical fitness, and investigating unexplained respiratory complaints that may have digestive origins.
