Cards

Term
Why is a 'pink puffer'?
Definition
a well perfused emphysema pt who struggles to breath
Term
What % of caloric energy does a 'pink puffer' extend on breathing?
Definition
30% of their calories
Term
Why do emphysema pt's present with a pursed lip expression?
Definition
Must maintain larger reserve volume to help prevent alveolar collapse
Term
What is 'tripoding?
Definition
Using arms to facilitate breathing by broadening the chest

hands are placed on the knees and shoulders brought slightly forward
Term
What are two signs of 'pink puffer' emphysema pts?
Definition
dyspnea

tachypnea
Term
Do 'pink puffer' pts have low pCO2?
Definition
If low, not by much. They can get O2, it just comes a large exertive cost
Term
What is chronic bronchitis?
Definition
persistent, productive cough on most days for at least 3 consecutive months in 2 consecutive years
Term
What are s/sx of chronic bronchitis?
Definition
wheezing

crackles

tachycardia

polycythemia
Term
In chronic bronchitis is it a dry cough?
Definition
no
Term
What is the prevalence of chronic bronchitis?
Definition
9.8 million pt's in the US
Term
Why does polycythemia present with chronic bronchitis?
Definition
The body senses low pO2 and makes more RBC's to try and increase O2 supply to the tissues
Term
Are the airways inflamed in chronic bronchitis?
Definition
yes
Term
What kind of cellular change is seen in the airway mucous glands when chronic bronchitis is present?
Definition
hypertrophy --> airway obstruction
Term
What are two sounds often heard with chronic bronchitis?
Definition
crackling and course lung sounds
Term
With chronic bronchitis, can coughing clear the airway of excess mucous?
Definition
Yes
Term
What is the #1 cause of chronic bronchitis?
Definition
smoking
Term
What are secondary causes of chronic bronchitis?
Definition
air pollution and infections
Term
What is a 'blue bloater'?
Definition
A stereotypical chronic bronchitis pt, they are blue because they can't clear enough CO2
Term
What lung dz presents with obese, edematous pts?
Definition
chronic bronchitis

Due to poor O2/CO2 exchange, pt reduces activity --> obesity
Term
Why does right sided heart failure appear in chronic bronchitis pts?
Definition
The lungs sense that there is not much O2 present, so it constricts attemping to divert blood to a well perfused area of the lung, that doesn't exist. Therefore the entire lung constricts --> increased blood flow resistance --> edema and right sided heart failure
Term
Why are chronic bronchitis pts happy and cyanotic?
Definition
CO2 buildup --> CO2 narcosis and poor O2 perfusion
Term
Do chronic bronchitis pts struggle to breath?
Definition
As long as they have enough O2 to avoid triggering peripheral chemoreceptors, then no.
Term
What are associated s/sx of chronic bronchitis?
Definition
decreased VA's at night

decreased color vision

transient visual obscurations

7% have swollen optic nerve heads

82% have decreased retinal fxn w/ abnormal VEP

increased risk of increased pCO2 and decreased blood pH
Term
What causes decreased VA's and decreased color vision in chronic bronchitis pt?
Definition
poor O2 perfusion in the retina
Term
What is the goal of chronic bronchitis and emphysema?
Definition
manage s/sx, avoid causative agent (smoking)
Term
How is chronic bronchitis treated?
Definition
treated similar to asthma

not curable however
Term
What are the 5 "A's" of smoking cessation?
Definition
Ask

Advise

Assess

Assist

Arrange
Term
If a smoker wants to quit, what steps should be taken?
Definition
set a quit date, ideally within two weeks

remove tobacco products from the home

Call a stop smoking support line
Term
What are drug tx classes for chronic bronchitis and emphysema?
Definition
bronchodilators and anti-inflammatory drugs
Term
What are the two types of bronchodilators for chronic bronchitis and emphysema tx?
Definition
short acting Beta 2 agonists

long acting Beta 2 agonists
Term
What is theophylline?
Definition
bronchodilator that is more toxic, causes seizures and arrythmias
Term
What is a controversial tx of chronic bronchitis and emphysema?
Definition
glucocorticoids

May be useful during exacerbations

May decrease number of exacerbations
Term
Is oxygen therapy used in tx of chronic bronchitis and emphysema?
Definition
yes, show to prolong survival. Used primarily for chronic bronchitis
Term
Are AB's used to tx chronic bronchitis and emphysema?
Definition
yes, decreases frequency and severity of exacerbations

reduces mortality
Term
Why are glucocorticoids controversial for chronic bronchitis tx?
Definition
They compromise lung immune system and may lead to increased infection
Term
What is a bronchial valve?
Definition
umbrella shaped device that is placed in the bronchioles to block airflow to diseased lung regions. NOT used yet, experimental
Term
What are phoshodiesterase inhibitors?
Definition
PDE-4 enzyme inhibitor, limits inflammation of airway smooth muscle and airway nerves
Term
Do steroid/statin combos show promise for chronic bronchitis tx?
Definition
yes, may have anti-inflammatory effect
Term
What vaccine has been shown to reduce morbidity and mortality in chronic bronchitis and emphysema pts?
Definition
influenza vaccine
Term
What are surgical tx's for emphysema?
Definition
bullectomy --> reduce compression of surrounding tissue

volume reduction surgery --> remove part of lung to prevent pressure and collapse of less diseased parts --> more space in thoracic cavity for diaphragm
Term
