PFT reader

PFT reader v0.6

Only works in Chrome, does not work in Internet Explorer.

1) Copy from the first line of SentryNet Prod and downwards, see screenshot.

2) paste into textbox , click button

3) copy interpretation below and paste back

*disclaimer* all automatic interpretations still require review!

Still under construction - please email Cathy if something doesn't work!

Should look something like this when pasted:

To fix:

[ x] doesn't work for post-bronchodilator PFTs

[x ] identify bronchodilator significance - numbers were off

[x] doesn't work for nitrogen washout

[x] report severity [x] incorrect

[x ] FEV1 not reading correctly

[x ] DLCO corrected for hemoglobin - saying not corrected

[ ] air trapping, hyperinflation

[ ] diffusion capacity technically suboptimal

[ ] interpretation flow chart

[ x] flow for severity messed up for borderline values

All available options:
MECHANICS:Forced vital capacity (FVC) is normal.Forced vital capacity (FVC) is decreased.Forced expiratory volume in one second (FEV1) is normal.Forced expiratory volume in one second (FEV1) is decreased.FEV1/FVC is normal.FEV1/FVC is decreased.FEV1/FVC is increased.FVC and FEV1 in Asian Indians living in the US have been reported to range between 16 to 28% lower than Caucasian reference values.FVC and FEV1 in Filipino's living in the US have been reported to be 15% lower than Caucasian reference values.
FLOW VOLUME LOOP:Normal.Decreased expiratory gas flow at low lung volumes.Decreased expiratory gas flow at low and mid lung volumes.Decreased expiratory gas flow at all lung volumes.Narrowed.There is flattening of the inspiratory limb of the flow-volume loop.There is flattening of the expiratory limb of the flow-volume loop.Increased expiratory flows at high lung volumes.
LUNG VOLUMES:Total lung capacity (TLC) is normal.Total lung capacity (TLC) is increased.Total lung capacity (TLC) is decreased.Residual volume (RV) is increased.Residual volume (RV) is decreased.RV/TLC is increased.The lung volumes have not been corrected for ethnicity. Values for TLC and RV are, on average, 12% lower (7% for FRC) in African Americans compared with Caucasians.The lung volumes have not been corrected or ethnicity. Values for Asians and Asian Indian subjects are poorly defined but, on average, TLC, RV and FRC are 7% lower compared with Caucasians.
DIFFUSING CAPACITY FOR CARBON MONOXIDE:Normal.Increased.Decreased . (mild: >60%, Mod: 40-60%, Severe: <40%)The diffusing capacity remains abnormal when adjusted for lung volume.The diffusing capacity is normal when adjusted for the patient's hemoglobin.The diffusing capacity remains abnormal when adjusted for the patient's hemoglobin.The diffusing capacity is normal when adjusted for the patient's hemoglobin.The diffusing capacity was not adjusted for the patient's hemoglobin.The DLCO has not been corrected for ethnicity. Similar to lung volumes, DLCO values tend to be, on average, 6-8% lower in African Americans. This may be due to lower lung volumes. Corrections may similarly apply to other ethnicities with lower lung volumes.The diffusing capacity is technically suboptimal.
INTERPRETATION:The pulmonary function tests are normal.Normal mechanics and lung volumes.Lack of reproducibility of this study limits meaningful interpretation. Suggest a repeat study if the patient's clinical status permits.Mild obstructive ventilatory defect. (Mild: >70%)Moderate obstructive ventilatory defect. (Moderate: 60-69%)Moderately severe obstructive ventilatory defect. (Mod Severe: 50-59%)Moderate-severe restrictive ventilatory defect. (Moderate Severe: <60%)Severe restrictive ventilatory defect. (Severe: <50%)Very severe obstructive ventilatory defect. (Very severe: <35%)There is an additional restrictive defect present.There is a mixed obstructive and restrictive ventilatory defect.Mild restrictive ventilatory defect. (Mild: >70%)Moderate restrictive ventilatory defect. (Moderate: 60-70%)Severe restrictive ventilatory defect. (Severe: <50%)There is an additional obstructive defect present.However, when ethnicity is considered, the pulmonary function test may be normal.Air trapping is present.Air trapping and hyperinflation are present.There is an isolated reduction in the DLCO.Gas exchange is normal.Gas exchange is decreased.The decrease in diffusing capacity reflects the loss of pulmonary capillary surface area, as may be seen in emphysema, interstitial lung disease, and pulmonary vascular disease (including pulmonary emboli and pulmonary hypertension), anemia, liver disease and OSA.In the setting of airway obstruction, the decreased diffusing capacity suggests the presence of emphysema.The normal diffusing capacity argues against the presence of significant emphysema.There is significant improvement after administration of an inhaled bronchodilator.There is no significant improvement after administration of an inhaled bronchodilator.The lack of response to a single dose of an inhaled bronchodilator does not necessarily indicate irreversible airway obstruction.Flattening of the inspiratory limb suggests that a variable extrathoracic airway obstruction may be present.Flattening of the expiratory limb of the flow volume loop suggests that a variable intrathoracic airway obstruction may be present.Flattening of both the inspiratory and expiratory limb of the flow volume loop suggests that a fixed upper airway obstruction may be present.Resting room air saturation is % by pulse oximetry.Compared to the previous study of ,there are no significant changes in the pulmonary function tests.There are no previous tests available for comparison.
