Definition
|
|
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
|
|
Term
What kind of cellular change is seen in the airway mucous glands when chronic bronchitis is present? |

|
|
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
|
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 |
|
|

Is oxygen therapy used in tx of chronic bronchitis and emphysema? |
|
Definition
yes, show to prolong survival. Used primarily for chronic bronchitis |
