The study found that (19 percent) drivers showed normal Pulmonary Function Test (PFT). (80 percent) showed mild moderate-severe obstruction, of which (48 percent) were non-smokers and (52 percent) were smokers and the result concludes that auto rickshaw drivers have a high respiratory morbidity due to exposure to pollution.
Understanding Your Breathing Test Results
The first component of a PFT report is spirometry which mainly provides a measure of flow. This defines whether or not the person is obstructed. We define obstruction as an FEV1/FVC ratio of less than the 5th percentile of the values obtained for normals. This value varies according to the age and height of the patient but is generally between ...

Given the following PFT findings, calculate the FEV1% and FEV1% predicted. FEV1 2.46 L FEV1 predicted 3.98 L FVC 3.8 L FEV1% 64.7%. FEV1% predicted . 61.8%. When evaluating a PFT, the % predicted column should read between . 80 to 120 % to be considered normal. Name the three criteria used to calculate the predicted values: AGE. GENDER. HEIGHT

Normal values vary,depending on gender, age, race, and height .It is therefore not possible to interpret PFT without such information Hence it is important to ensure that reference formulas in a PFT lab are applicable to the patient population being tested.

If both FVC and FEV1 are normal, then patient has a normal PFT tests. If FVC and/or FEV1, is 80-90 % or higher, then patient has restricted lung disease. If the % predicted for FEV1/FVC is 69% or lower, then the patient has an obstructed lung disease.

Values. Normal adults should generate inspiratory pressures greater than -60 cm H2O (-80 to -120) Values of –20 cm H2O or less indicate a need for mechanical ventilation . MIP is a measure of inspiratory muscle strength & the patients ability to generate an effective cough. Decreased values are seen with. Neuromuscular diseases
