This document discusses pulmonary function tests and spirometry. It explains that pulmonary function tests can measure spirometry, bronchoprovocation, exercise capacity, lung volumes, diffusion capacity, and more. Prediction of normal data is based on height, age, gender, and race. The document also provides three case studies and notes that interpretation of pulmonary function test results requires a properly performed, accurate, and reproducible test along with a review of patient history and therapist notes.

4. Pulmonary function test Vs. spirometry
Spirometry
Bronchoprovocation
Exercise test
Caliomtery
Diffusion capacity
Lung volumes
Slow vital capacity
Or forced vital capacity

9. • ERV?
• TLC?
• IC?

10. Prediction of normal data is based on
• Height
• Age
• Gender
• Race

13. Start interpretation of PFT :
• After properly perform an accurate, good effort,
reproducible test
• After reviewing patient history
• After reviewing therapist notes

17. Case 1
• Khalid is a 45 years old man. Married with two wives.
He has a stressful life and he smokes one pack per
day since he was 15.

19. Case 2
• Huda is a 34 years female. She is the the first wife
she has a stressful life. She complains of SOB while
climbing the stairs.

21. Case 3
• Sami is the family driver. He worked in asbestosis
before changing his job into driver. He smokes 2
packs a day

22. • FEV1/FVC 60%
• FEV 69%
• TLC 60%

23. Take home messages
• Most of PFTs are effort dependent
• Great therapist is the one who obtain the best of the
patient ( Scream if needed ! )
• Great therapist can look at the results and make sure
it is accurate and reproducible
• PFT is not a diagnostic tool by itself
• It is very important for thoracic and abdominal
surgeries.
