T2 - Asthma, Sarcoidosis, Lung Cancer (Josh) Flashcards
What happens to bronchioles during asthma?
obstructed on expiration due to muscle spasm, edema of mucosa, and thick secretions
Statistics of Asthma:

1000 hospital admissions daily ; 500,000 annually
10.5 million PCP visits each year
***Increases odds of needing medical treatment by 33% for obese clients
Statistics of Asthma:
What is the prevalence of Asthma in U.S.?
20 million americans
300 million worldwide
more common in adult women than men
more common in AA than Whites
***Number continues to increase
Statistics of Asthma:
What is the cost of Asthma in U.S.?
$ 19.7 billion annually
$3,300 per person annually
Asthma:
What are the two steps of Asthma?
Inflammation
Airway hyperresponsiveness leading to bronchoconstriction
Asthma:
Pathophysiology
Intermittent and resversible airflow obstruction affecting airways only, not alveoli
***AIRWAYS ONLY, NOT ALVEOLI
Asthma:
How could ASA and other NSAIDS trigger asthma?
increased production of leukotriene while suppressing other inflammatory pathways
Asthma:
What are some triggers of the Inflammation process?
Cold air
Dry air
Specific Allergens
General Irritants
Microorganisms
ASA
Asthma:
What are some triggers of the Hyper-Responsiveness process?
Exercise
URI
GERD
unknown reasons
Asthma:
What are some clinical manifestations?
Audible wheeze
Increased RR and cough
Use of accessory muscles
Barrel chest
Long breathing cycle
Cyanosis
Hypoxemia
Asthma:
What may happen to CO2 during asthma attack?
arterial CO2 may decrease (alkalosis) early in attack and increase (acidosis) later
***indicating poor gas exchange
Asthma:
What would serum eosinophil levels and Immunoglobulin E levels look like?
elevated
Asthma:
What is most accurate way to assess Pulmonary Function?
Spirometry
What is Forced Vital Capacity (FVC)?
volume of exhaled air from full inhalation to full exhalation
What is Forced Expiratory Volume in First Second (FEV1)?
volume of air blown out as hard and fast as possible during the first second after a full inhalation
***decreases by 15-20% of expected value is common in asthma
What is Peak Expiratory Flow Rate (PEFR)?
fastest airflow rate reached during exhalation
Asthma Severity:
What is Mild Intermittent?
symptoms less than twice a week
Asthma Severity:
What is Mild Persistent?
symptoms more than twice a week, but not daily
Asthma Severity:
What is Moderate Persistent?
daily symptoms, with exacerbations twice a week
Asthma Severity:
What is Severe Persistent?
symptoms occur continually with frequent exacerbations
Asthma Meds:
Which bronchodilator would not be first choice due to narrow therapeutic range?
Theophyline
Asthma Meds:
What anti-cholinergic is often used as a bronchodilator?
ipratroprium
Asthma Meds:
What are the anti-inflammatory agents?
Corticosteroids
Cromones (cromolyn)
Leukotrien Modifiers (reduce inflammation)
Status Asthmaticus:
What is it?
severe, life-threatenine, acute episode of airway obstruction
Status Asthmaticus:
Does patient respond to normal asthma meds?
no
Status Asthmaticus:
What are some complications?
Pneumothorax
Cardiac / Respiratory arrest
Status Asthmaticus:
What is treatment regimen?
IV fluids
Potent Systemic bronchodilator
Steroids
Epi
O2
