|
|
Term
|
Definition

|
Term
| lung disease can be classified into one of three categories |
|
Definition
obstructive
restrictive
vascular disease |
|
|
Term
|
Definition
diaphragm contracts and moves down
negative pressure within the thorax develops
causes air to move into the lungs from mouth |
|
|
Term
|
Definition
diaphragm relaxes and moves upward
rib cage moves inward
allows air to move from the lungs to the mouth
assisted by elastic recoil |
|
|
Term
|
Definition
| progressive expiratory airflow obstruction |
|
|
Term
|
Definition
dyspnea at rest and with exertion
cough and sputum production |
|
|
Term
|
Definition
nonuniform narrowing of airways secondary to inflammation
loss of elastic recoil
increased RV at the end of forced expiration
causes diaphragm to flatten |
|
|
Term
|
Definition
| lack of elastic recoil and smaller airway occurs |
|
|
Term
| pink puffers often report |
|
Definition
dyspnea
are barrel chested
have little cough/sputum production
typically thin |
|
|
Term
|
Definition
reduced FEV1/FVC ratio
elevated TLC |
|
|
Term
| chronic bronchitis characterized by |
|
Definition
cough and mucous production
involves abnomalities of larger aiways
|
|
|
Term
| chronic bronchitis often associated with |
