cough
tachypnea
tachy
pulsus paradoxus (severe exacerbations)
mild asthmatic attack
mild dyspnea
wheezing
moderate asthmatic attack
resp distress at rest
marked wheezing
severe asthmatic attack
marked resp distress
loud wheezing
cough
diffulty speaking
accessory chest muscle use
chest hyperinflation
resp failure attack
severe resp distress
confusion
lethargy
cyanosis
disappearance of breath sounds
pulsus paradoxus >12mm Hg
diagnostic test results
pulmonary function test
bld analysis
sputum analysis
pulse oximetry
arterial bld gas measurements
ECG
chest radiography
allergy skin tests
pulmonary fxn test
determine the degree of airway obstruction and maybe between exacerbations
forced expiratory vol 1 second (FEV1)
forced vital capacity
dec during acute exacerbation
residual volume
total lung capacity
inc due to air trapping and lung hyperinflation
peak expiratory flow rate(PEFR)
correlates well with fev1
not used in dx of asthma
best measured early am
diurnal variation > 20%in PEFR
suggest airway hyperresponsiveness and less than adequate asthma control
assess hyperresponsiveness and rule out asthma
provocation testing w/ histamine or methacholine challenge
inc WBC
bld analysis -> acute exacerbation
sputum analysis reveals
eosinophils
curschmann's spirals
charcot-Leyden crystals
creola bodies
bacteria
curschmanns spirals
mucous casts of the small airways
charcot-leyden crystals
prodts of eosinophil breakdown
creola bodies
clumps of epithelial cells
pulse oximetry
noninvasive means of assessing the degree of hypoxemia during an acute exacerbation
oximeter
measures oxygen saturation in arterial blood (SaO2) and pulse
arterial bld gas measurements
help gauge the severity of the asthma exacerbation
hyperventilation
early stages of asthma exacerbation
dec in partial pressure of arterial carbon dioxide
resp acidosis
poor prognostic sign

develops if hypoxemia worsens and pt;s resp rate is not maintain due to resp fatigue -> rising PaCO2 level
ECG
show sinus tachy
older pt
radioallergosorbent test
helpful in id possible allergic triggers
signs of resp distress
use of accessory muscles
inability to speak in sentences
ambulate due to dyspnea
declining mental status
PEFR less than 50%
cyanosis
suprasternal retractions
abs of resp sounds
inc PaCO2
