Session 12_Asthma Flashcards
What is impacted in obstructive pulmonary disease?
flow
In obstructive pulmonary disease air gets _____________________________.
Trapped in the lungs
Examples of obstructive diseases are:
- emphysema
- asthma
- chronic bronchitis
Examples of septic obstructive pulmonary diseases are:
- cystic fibrosis
* bronchiectasis
From which type of obstructive disease are you more likely to get an infection?
septic
Emphysema is caused by a destruction of the air spores. Describe the differences in how the alveoli appear:
normal alveoli are pink, and nicely rounded.
In emphysema the air spaces areas are stretched out and appear darker in appearance.
What is impacted in restrictive pulmonary disease?
volume
In restrictive pulmonary disease its hard to get air ____________ and in obstructive pulmonary disease it is hard to get air _________.
IN
OUT
Restrictive pulmonary disease is:
- linked to immune disorders, occupational exposures, genetic and hormonal abnormalities and a complication of lung injury
- loss of lung compliance and chest wall expansion
- decreased depth and increased rate of breathing
In restrictive pulmonary disease, the lung tissue is less _____________ and becomes ___________________
less elastic
tighter and tougher

normal FEV1 =
80%-120%
with restrictive FEV1/FCV ratio =
> 80%
Normal FEV1/FVC ratio =
70-80%, ~75%
in obstructive disease, the ratio of FEV1/FCV :
decreases
FVC is stable and FEV1 is smaller
Asthma is an example of what type of pulmonary disease?
obstructive
Asthma is a chronic disease characterized by _____________ obstruction to airflow within the lungs.
reversible
list some risk factors of asthma:
- childhood asthma
- family history
- atopy (hypersensitive skin response to common irritants)
- maternal smoking
- occupational exposure
- environmental exposure
- secondary smoke
- gender - (female 2-fold increase)
rhinitis =
inflammation of the nose / sinuses
Of children with asthma 77% have _________________, 17% have _____________ and 91% have __________________.
77% have had allergic rhinits,
17% had eczema and
91% have a family history of allergy in 1st degree relative.
