Flashcards in Chapter # 1, Indications Deck (61):
Identify and quantify pulmonary impairments
PFT Category tests
1. Airway Function
2. Lung Volumes and Gas Distribution
3. Diffusing Capacity
4. Blood Gas and Exchange Tests
5. Cardiopulmonary Exercise Tests
What Test is the most common on PFT?
It measures the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
It measures how well air moves in and out of the airways
Lung Volume test measures?
How big the lungs are
Diffusion Capacity test
How well does gas pass through alveolar capillaries
The most common Airway Function Test is?
Vital Capacity is?
Is the total amount of air that we can exhale after a maximum inspiration
Vital Capacity is also known as
Slow vital Capacity
Force Vital Capacity (FVC), measures
FVC measures Volume and Flow
when we think about obstruction we should think on ...
It may be the fist test to identify pulmonary disease ...
Spirometry is the most common PFT test, it measures air flow including:
1. VC (irv, vt, erv)
Drugs that are use to induce an Asthmatic Attack?
People who do not have asthma, how they will react to an induce Asthmatic attack?
These people will not have any reaction to these drugs.
How we can determine if a patient have Asthma or not?
By inducing an Asthma Attack
The Gold standard to Diagnose an Obstructive Lung Disease is?
Obstructive Diseases will reduce ...
Airflow in and out of the lungs
What does mean CBABE, and what have in common?
Empfysema, and they are all OBSTRUCTIVE diseases.
1. Diagnose the presence or Absence of lung diseases.
2. Quantify the extent of known disease on lung
3. Measures the effects of occupational or
4. Determine beneficial or negative effects to therapy.
5. Assess risk of surgical procedures.
6. Evaluate disability or impairment.
Lung Volume test is the Gold Standard to identify...
RESTRICTIVE lung disease.
Indication for lung volume test?
1. Diagnose or assess severity of restrictive lung
2. Differentiate between restrictive and obstructive
3. Make preoperative assessments of patients with
compromise lung function.
Indication for Blood Gas analisis
1. Evaluate adequacy of lung function.
2. Determine the need for supplemental Oxygen.
3. Document severity or progression of known
Indication for Diffusing Capacity
1. Evaluate or fallow the progress of parenchymal lung
2. Evaluate pulmonary involvement in systemic
4. Evaluate cardiovascular disese
Previous test, We should stop giving short acting B-Agonist?
Long acting B- agonist should be stpo
12 hours previous test
Atropin like preparation
Ipatropium Bromide (Atrovent), 8 hours before
Cromolyn Sodium, 8-12 hours previous test
What is COPD
Is a long standing airway obstruction, caused by Bronchitis, Asthma and Emphysema.
this condition may be present alone or in combination .
COPD is characterized by:
- Dyspnea at rest or Exertion
- Productive cough
Means air trapping
+ Caused primarily by cigarette Smoking
+ As the disease advances more and more alveolar
wall are destroyed
The main Symptom of Emphysema is?
Breathlessness , either at rest or with exertion.
In advanced Emphysema, what contribute to Dyspnea?
On Emphysema DLCo will be
On Emphysema Chest X-Ray will show
+ Flatted Diaphragms and increased air spaces
+ The lungs appears hyperlucent (Dark)
+ Heart appears to be hanging from the great vessels
What Enzyme deficiency causes the gradual destruction of the alveolar wall?
On Emphysema FEV1 will be?
It is present when there is excessive mucus production, with a productive cough on most days, for at least 3 months for 2 years or more.
Chronic Bronchitis main cause
Smoking Cigarettes, also exposure to environmental pollutants
What test may be used to distinguishing between Emphysema and Chronic Bronchitis
DLCo, Chronic Bronchitis patients may have preserved DLCo, while Emphysema patients DLCo is reduced
Is the pathologic dilation of the bronchi
The main feature of Bronchiectasis is:
Very productive Cough, the sputum is usually purulent and foul smelling.
Treatment of Bronchiectasis?
Bronchoscopy and surgical resection
The most common presentation of Asthma include:
shortness of breath
Disease that primarily affects the mucus production apparatus of the lung and pancreas?
Clinical manifestation of CF include:
+ Chronic Cough and Sinusitis
The primary management of CF is:
Removal of excess of mucus produced.
Symptom of Sarcoidosis include:
Fatigue, muscle weakness, fever and weight loss
What disease shows relatively normal flows on PFT?
Dyspnea and Dry, nonproductive cough are the most common symptoms for ...
+ Under weight
+ Use accessory muscles
+ Purse-lip breathing
Is characteristic of what condition?
On patient preparation, Smoking cessation should be ceased
24 hour prior test
On patient preparation, Eating should be limited to:
Alcohol consumption should be refrain for:
4 hours before testing
DO NOT ask for this information on physical measurements
+ Height in inches or
+ Weight in pounds or
Any disease that causes problem with lung volume will make the patient breath...
Indication for Spirometry include which of the following?

4. Measurements of the effects of working in a dusty enviriment.
A. 1,2 and 3
B. 1,3 and 4
C. 2,3 and 4
D. 2 and 4 only
B. 1,3 and 4
What test would you suggest to an adult with suspected shunt?
which of the following diseases often result in an obstructive pattern when Spirometry is done?
a. 1,2 and 3
b. 1,3 and 4
c. 2,3 and 4
d. 2 and 4
a. 1,2 and 3
Which of the following should a pulmonary function technologist do before performing Spirometry?
a. Administer an anticholinergic
b. ask the patient their current height and weight.
