TEST BANK For Ruppel’s Manual of Pulmonary FunctionTesting 12th Edition By Mottram
What measurements do PFT's provide? - ANSWER:They provide measurements of:
airway function and mechanics
lung volumes
gas exchange and cardiopulmonary exercise tolerance
What computerized equipment do most PFT labs have? - ANSWER:Spirometer
Body plethysmograph
Diffusion system
What are the indications for a PFT? Why do we need them? - ANSWER:Diagnostic
Monitoring
Disability
What are the Diagnostic uses of PFT's? - ANSWER:Evaluate symptoms, signs or
abnormal lab tests
Measure effect of disease on pulmonary function
Screen individuals at risk of having pulmonary disease
Assess pre-operative risk and/or health status prior to exercise program
What are the Monitoring uses of PFT's? - ANSWER:Assess the change in lung function
over time
Evaluate change after administration/change in drug therapy
Monitor for adverse reactions to drugs with know lung toxicity
Assess the potential effects of environmental/occupational exposures
What are the Disability uses oof PFT's? - ANSWER:Assess impairment of disability
from lung disease
Assess risks as part of insurance evaluation
What are contraindications of PFT's? Why wouldn't I do PFT's? - ANSWER:Myocardial
infarction within 1 month
Conditions where suboptimal lung function results are likely:
Chest or abdominal pain of any cause
Oral or facial pain exacerbated by a mouthpiece
Dementia or confused state
What are the patient preparation steps for a PFT? - ANSWER:Get Patient history
What arePresent symptoms/smoking history (packs x years=pack years)

capacities decreas as a person ages
Gender: females have smaller lung volumes and capacities
Height: the taller the person, the larger the lung volumes and capacities
BSA: When used to predict and expected value-use ideal body weight
Race: Differences in lung volumes and capapcities are due to differences in body
proprotions and stature-race correction factors are used
What are the ranges for PFT results? - ANSWER:Normal: 80-120 % of predict value
Mild disorder: 60-79 %
Moderate disorder: 40 59%
Severe disorder: less than 40%
What is the formula for calculating % Predicted? - ANSWER:% Predicted=Measured
Value/Predicted Normal Value X 100
What are the 3 physiologic classifications of pulmonary disease? -
ANSWER:Obstructive diseases
Restrictive diseases
Combined diseases
What does routine PFT spirometry measure? - ANSWER:It measures to basic
components:
Volume
Flow
What does obstructive lung disease cause? - ANSWER:It causes reduced expiratory
flows
What does restrictive lung disease cause? - ANSWER:It causes reduced lung volumes
What does combined lung disease cause? - ANSWER:It causes both reduced
expiratory flow and reduced lung volumes
What are examples of Obstructive lung diseases? - ANSWER:Emphysema
Asthma
Acute/Chronic Bronchitis
Bronchiectasis
