Obstructive Pulmonary Disease (OPD) Flashcards

1
Q

What is obstructive pulmonary disease (OPD)?

A

Any disease of the airway the produces restriction to expiratory airflow, resulting in delayed and incomplete emptying of the lungs during exhalation- difficulty getting air OUT

Q

T/F exhalation becomes active in those with OPD

A

True- exhalation becomes forced due to the inability of a passive exhale b/c of the flattened diaphragm and during inspiration the accessory muscles have to be recruited

Q

what is used to measure if a patient is getting a complete emptying of their lungs during exhale?

A

Spirometer: measures how fast and how much air you can blow out of your lungs
-FEV1: forced expiratory volume
-FVC: forced vital capacity
a normal FEV1/FVC= >75% (how much of the air that can be forcefully expired can be expired in 1 second)

**the ratio decreases as the severity of the disease increases

Q

Random COPD S/S

A

-clubbing fingers
-cyanosis
-auscultation of lungs will show a prolonged expiratory phase (>4 seconds)
-breath sounds are diminished
-jugular vein distension
-ankle/lower leg swelling when CHF is present

22
Q

What is the gold standard for diagnosing COPD and monitoring its progression?

A

Pulmonary function tests
-decreases in FEV1 and FEV1/FVC values
-spirometry is the best objective measure of airflow limitations

23
Q

How to diagnosis COPD?

A

-pulmonary function tests
-X-ray
-CT
-Sputum culture (looking for infection)
-CBC and check blood gases

24
Q

T/F if a patient’s spirometer measure is abnormal, the test is repeated again after using a bronchodilator- those with asthma will then have normal results and those with COPD will only see a partial improvement

A

True

25
Q

What is the BODE index used for? && what does it stand for?

A

To predict the survival of those with COPD
-B: body mass
-O: obstruction
-D: dyspnea
E: exercise

26
Q

What does end stage COPD result in?

A

R sided heart failure (cor pulmonale)

27
Q

Goals of COPD management

A

-relieve symptoms
-prevent disease progression
-improve exercise tolerance
-reduce mortality

28
Q

Which medications are used for COPD management?

A

-bronchodilators
-anti-inflammatories: glucocorticoids or corticosteroids
-antibiotics

29
Q

What is cystic fibrosis?

A

A multisystem disorder that effects every organ system that has epithelial surfaces
**most predominant are the lungs and pancreas

30
Q

How does cystic fibrosis affect the pulmonary system?

A

causes chronic obstruction and inflammation, thick mucus, and recurrent bacterial infections- results in failure of airways to clear mucus normally

31
Q

How does cystic fibrosis affect the pancreas?

A

it develops exocrine pancreatic insufficiency which then effects GI function and growth and development

32
Q

How is cystic fibrosis diagnosed?

A

-newborn screen (CFTR mutation screen)
-sweat test: elevated chloride levels (>60 mEq/liter)

33
Q

What are the management goals of cystic fibrosis?

A

-control lung infections
-promote mucus clearance
-improve nutrition status

34
Q

Implications for PT for those with cystic fibrosis, or those with asthma

A

-secretion clearance
-controlled breathing
-exercise and strength training
-inspiratory muscle training
-thoracic stretching
-postural eduction

35
Q

What is asthma?

A

Airway resistance caused by constriction of the bronchial smooth muscle cells and mucus production within the airway- chronic inflammatory disorder of airway

36
Q

What are the causes of asthma?

A

-viral or allergen exposures
-exercise
-inhalation of cold air

37
Q

Symptoms of asthma

A

-wheezing
-chest tightness
-SOB

38
Q

What are the special types of asthma?

A

-seasonal
-exercise-induced
-asthmatic bronchitis

39
Q

T/F 50% of those who have childhood asthma continue to have symptoms into adulthood

A

True

40
Q

What is bronchiectasis?

A

Dilation of the bronchials- it is irreversible with chronic inflammation and infection

41
Q

What can cause bronchiectasis?

A

-bronchial wall injury or structural weakness
-traction from adjacent lung fibrosis
-bronchial lumen obstruction

42
Q

Symptoms of bronchiectasis

A

-cough with sputum production
-secretion layers (white frothy, mucoid inner, purulent bottom, composed of thick yellow-green plugs)
-sputum greatest in morning
-recurrent, chronic, or recurring lung infections
-hemoptysis

43
Q

Diagnostic tests for bronchiectasis

A

-CT scans PFTs
-blood work (blood gases abnormal)
-sputum testing (H. Influenzae and P. aeruginosa)
-evaluation of GERD

44
Q

Goals of management for bronchiectasis

A

to reduce the number of exacerbations and improve quality of life

45
Q

Which OPD has the poorest prognosis?

A

CF and bronchiectasis both have the poorest

46
Q

What is the most common drug class used to treat respiratory disorders?

A

bronchodilators- work by relaxing the smooth muscle within the bronchi and brinchioles to open the airway and make it easier to breath

47
Q

what are the 2 types of bronchodilators?

A
  1. short-acting: work quickly after you take them so you feel relief from symptoms quickly
  2. long-acting: have long lasting effects and should not be used for quick relief (dilates airway for up to 12 hours)
48
Q

what are the common side effects of bronchodilators?

A

-increased HR
-HA
-anxiety
-tremor

49
Q

T/F the timing of bronchodilators doesn’t matter

A

False- they should be administered prior to therapy session to allow for optimal respiratory function

50
Q

What is the goal of supplemental oxygen?

A

To increase oxygen saturation- but too much supplemental oxygen can be dangerous for patients with COPD
-O2 levels may rise with the use of less oxygen as opposed to increasing the oxygen

**>88% of O2 sat is normal for the respiratory population
