Keeping this in view, what is a normal reading on a spirometer?
Interpretations of spirometry results require comparison between an individual's measured value and the reference value. If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65).
Secondly, how do I prepare for a spirometry test? How to prepare for the test:
- Do not smoke for one hour before test.
- Do not drink alcohol within four hours of test.
- Do not eat a large meal within two hours of test.
- Please wear loose clothing.
- Do not perform vigorous exercise within 30 minutes of test.
Beside above, how long should I use my incentive spirometer?
Hold your breath as long as possible (at least for 5 seconds). Then exhale slowly and allow the piston to fall to the bottom of the column. Rest for a few seconds and repeat steps one to five at least 10 times every hour. Position the yellow indicator on the left side of the spirometer to show your best effort.
