•Provide objective and quantifiable measures of lung function
•Can be used to diagnose, evaluate, & monitor various respiratory diseases •Can assess risk of exposure to environmental triggers •Can help measure the effectiveness of therapy |
Pulmonary Function Test
|
|
|
What are the types of pulmonary function tests?
|
Spirometry: A type of PFT that measures the movement of air into & out of the lungs (most common PFT)
•Other PFTs: –Exercise Testing –Plethysmography –Bronchoprovocation Challenge Test –Carbon Monoxide Diffusion Capacity |
|
|
Measures 2 main things:
•The amountof air exhaled –Think ―volume‖ •The speedin which air is exhaled –Think ―Flow‖ |
Spirometry
|
|
|
Successful SpirometryManeuvers
•Require 3 main things: what are they? |
•Require 3 main things:
–Full inspiration –Forceful expiration –Complete expiration •Most maneuvers are ―effort dependent‖ and require ―coaching‖ •Must perform at least 3 times to assess: –Acceptability –Reproducibility |
|
|
With baseline demographics of a patient what is the critical information?
|
Critical Information
–Age –Height –Gender –Race –Diagnosis |
|
|
With baseline demographics of a patient what is the additional information?
|
Additional Info
–Test conditions –Posture –Clothing type –Medications –Loose dentures –Nose clips worn –Smoking history |
|
|
A print out of a spirometry test result usually has the following: What are they?
|
–Volume/Time Curve
–Flow/Volume Curve –Demographic information –List of measurements –―Normal‖ predicted values •National Health & Nutrition Examination Survey (NHANES) |
|
|
What results paint a patient as "normal"?
|
If a patient is within 80% of the mean that means they are normal.
|
|
|
–Lead to a decrease in airflow
–*No change in volume of air the lungs hold |
Obstructive Disorders: Asthma and COPD (reversible versus irreversible)
|
|
|
–No change in airflow (usually)
–Decrease in volume of air the lungs can hold |
Restrictive Disorders: Kyphosis, chest wall deformities, pleural effusions (TB, CHF), and sarcoid
|
|
|
•Bronchodilator response
–Pre-bronchodilator test –Administer bronchodilator –Wait 15-30 minutes –Post-bronchodilator test –≥12% FEV1and 200ml increase is ―consistent‖ with asthma |
“Reversibility” Testing
|
|
|
What are the two types of reactivity testing?
|
Exercise Testing
•Bronchial Provocation Tests (BPT) |
|
|
A type of reactivity testing?
–6-min Walk Test –Cardiopulmonary Exercise Testing (CPET) •≥10% FEV1decrease from baseline may suggest EIA |
Exercise Testing
|
|
|
A type of reactivity testing?
–Adenosine challenge –Histamine challenge –Methacholine challenge •≥20% FEV1decrease from baseline reversed by a SABA suggests hyperresponsiveness •PC20FEV1(mg/ml) –<1.0mg/ml mod-severe BHR –1-4mg/ml mild BHR –4-16mg/ml borderline BHR –>16mg/ml normal BHR |
•Bronchial Provocation Tests (BPT)
