PRACTITIONERS.
Pulmonary Function Tests/Spirometry: What can cause it to vary?
-Age
-Sex
-Height
-Weight
Pulmonary Function Tests/Spirometry: Used to evaluate
-Peop eval of lungs and pulmonary reserve
-response to bronchodilator therapy
-differentiate between restrictive and obstructive chronic pulmonary disease
-Determine capacity of lungs
-Inhalation allergy tests
Pulmonary Function Tests/Spirometry: What tests do they include?
-Spirometry
-Airflow measurement
-Lung volume
-Lung capacity
Forced Vital Capacity (FVC)
Amount of air that can be forcefully expelled from a maximally inflated lung position.
,What does a reduced forced vital capacity suggest?
Obstructive and restrictive pulmonary diseases.
Forced expiratory volume in 1 second (FEV1)
Volume of air expelled during the first second of FVC
What are the findings of FEV1 in obstructive pulmonary disease?
Airways are narrowed
Resistance to flow is high
Numbers of FEV1 are less than predicted because not so much air can be expelled in
1 second.
FEV1: What are the findings in restrictive lung disease?
Decreased because amount of air originally inhaled is low, instead of airway
resistance.
What is a normal FEV1/FVC ratio in restrictive lung disease?
80%.
What is a normal FEV1/FVC ratio in obstructive lung disease?
Less than 80%
Under what condition will the FEV1 value reliably improve?
With bronchodilator therapy with a spastic component to obstructive pulmonary
disease exists.
,Normal results of Spirometry
Greater than 80% of expected value
Airflow rate: When is it considered diminished?
Less than 60% of normal.
What helps to increase airflow rate and by how much?
20% by with bronchodilator
Diagnosis of COPD requires what?
Demonstration of persistent airflow limitation based on spirometry testing.
After bronchodilator, FEV1/FVC of less than 70%.
Classification of COPD severity is based on what?
Assessment of spirometry testing at regular intervals
How does COPD compare with asthma?
Onset later in life.
Slower progression of symptoms.
Poorer response to inhaled therapy.
, Polysomnography
Sleep study
When is a polysomnography indicated?
When any person:
snores excessively
-Experiences narcolepsy
-Excessive daytime sleepiness
-Insomnia
-Motor spasms while sleeping
-Cardiac rhythm disturbances when sleeping.
What does a polysomnography test most commonly diagnose?
Sleep apnea
What is a actigraphy?
A watch that can be worn a few nights at home
What is a bronchoscopy used for?
Performing diagnostic and therapeutic procedures
What can you use a bronchoscopy for?
Visualization of a tracheobronchial tree
-Transbronchial and Endobronchial biopsy
-Bronchoalveolar lavage
-Removal of foreign bodies
-Clots
-Mucus plugs
