wk 2 asthma ppt/1 Flashcards
acute asthma episode can cause
respiratory distress
is asthma reversible
yes
_____ inhibitors are also used for asthmatics
leukotrienes
s/s of hypoxemia
6
- restlessness
- increased anxiety
- inappropriate behavior
- increase PR
- increased BP
- pulse paradoxus (low SBP during inspriation)
I/E ratios of asthma
3
1: 2
1: 3
1: 4
most effective for inflammation from persistent asthma
ICSs/fluticasone
asthma - what is effective in treating inflammation
corticosteroids
drugs to open airways
bronchodilators
acute asthma episode severity is measured with
flow rates
intermittent asthma drugs step 1
SABA as needed
asthma late phase
occurs within 4-10 hours after attack
asthma dx studies
9
- detailed H&P
- pulmonary function tests
- peak flow monitoring
- chest x ray
- ABGs
- oximetry
- allergy testing
- blood levels of eosinophils
- culture
SABA ex
albuterol
asthma patho - inflammatory mediators cause
early phase response
classification of asthma
4
- mild intermittent
- mild persistent
- moderate persistent
- severe persistent
asthma causes airway what
hyperresponsiveness leading to wheezing, breathlessness, chest tightness, and cough
s/s of asthma in early stages
persistent cough
asthma severe acute attack
3
- RR >30
- PR >120
- PEFR is 40% at best
asthma
chronic episodic inflammatory disorder of airways
asthma percussion of lungs
hyperresonance
drugs to reduce inflammatory response
steroids
severe exacerbation treatment
3
- three treatments of SABA spaced 20-30 mins apart
- IV steroids every 4-6 hours
- IV mag sulfate as bronchodilator
asthma - what narrows the airways
3
- bronchospasm
- edema
- mucus in narrow airways
cough variant asthma
2
- cough is only s/s
2. bronchospasm is not severe enough to cause airflow obstruction
