SPIROANALYSER

MEASURING LUNG FUNCTION

1. Instruments

A: Spiroanalyser
Spiroanalyser is a medical device used to assess the patient's lung function. It is a type of spirometer that measures how fast the air flows in or out as the volume of air inhaled or exhaled increases
B: Mouthpiece
C: Nose clip

2. Indications of performing the test

• To evaluate the extent and progress of the disease
• To monitor the effectiveness of treatment
• To assess the risk for surgical procedures

3. How to perform the test

4. Parameters obtained from the procedure

FVC : Force Vital Capacity
FEVT : Forced expiratory volume timed
FEV1 : Forced expiratory volume in one second
PEF : Peak expiratory flow
FEV1/FVC ratio

5. Interpretation of spirometry results

Examples of diseases

• Obstructive pulmonary diseases: emphysema, chronic bronchitis, bronchial asthma
• Restrictive pulmonary diseases: fibrosis, sarcoidosis, neuromuscular disorder, chest
wall abnormalities
