What is asthma?
chronic inflammation causes swelling and irritation of the airway lining
What can result from inflamed airways?
hyperresponse; reacts strongly to allergens, irritants, and respiratory infection
What results from airway narrowing?
wheezing, cough, chest tightness, and dyspnea
When does inflammation occur?
persist between episodes; can cause airway remodeling and more persistent obstruction
What are ways that the airway narrows?
bronchoconstriction, mucosal edema, thick mucus
What is bronchoconstriction?
smooth muscle tightens
What is mucosal edema?
the airway lining swells
What results from airway narrowing?
resistance and work of breathing increase
What is airflow limitation of asthma?
typically variable, often reversible
What is airflow limitation of COPD?
persistent
What are the main changes of asthma?
inflammation and bronchodilation
What are main changes of COPD?
small-ariway disease and alveolar demage
What is the pattern of asthma?
varies with time and triggers
What is the pattern of COPD?
often persistent, with exacerbation
What are shared findings between asthma and COPD?
dypnea, wheezing cough
What is asthma etiology and triggers?
allergens; smoke, pollutants, and other irritants; respiratory infections; exercise or cold air
What medication can trigger asthma?
aspirin and NSAIDs
Who is 4x more likely to get asthma?
black americans in comparison to white americans
Who is twice as likely to get asthma?
hispanic/latino in comparison to white americans
What is 20% more likely to get asthma?
Native Americans more than white americans
What are questions to ask about asthma history?
dyspnea, chest tightness, cough, and wheezing
What should be asked about asthma symptoms?
timing, frequency, and duration
What are common cues for asthma?
nightime awakening and activity limitations
What should be assessed for asthma history?
triggers, medication use, and response
What should be asked about past medical history for asthma?
pervious ED visits, hospitalization, and intubation
What are physical cues for asthma?
expiratory wheezing and pronlonged expiration
What are physical symptoms of asthma?
cough, dypnsea, and chest tightness
What can result physically from asthma?
increased RR and work of breathing
What is phsycially excessively used in asthma?
acccessory muscle use and retractions
What is difficult during asthma?
speaking between breaths
What are signals of hypoxemia?
restlessness, agitation, tachycardia
What is spirometer?
measures expiratory airflow
What is bronchodilator testing?
assesses improvement
What is peak flow?
monitors changes
What is pulse oximetry?
assess oxygen saturation
What is peak expiratory flow?
measures how quickly to patient can force air out
What should the PEF be compared to?
patient’s personal best
What are the steps of PEF?
full breath, seal lips, and blow harda and fast
What are treatment goals for asthma?
control and prevent episodes, reduce severe exacerbations
What do we want to improve for asthma?
airglow and gas exchange
What do we want to minimize for asthma?
symptoms and activity limitations
What do we want to support during asthma?
effective self-management
What is maintenance treatment?
provides ongoing asthma control
What is reliever treatment?
addresses symptoms quickly
What may persist when asthma syptoms are absent?
airway inflammation
What should asthma treatment include?
inhaled corticosteroid
What do some prescribed combination inhalers serve?
maintenance and reliver roles (both)
What is important for medication compliance?
continue the prescribed regimen even when feeling well
What are SABAs?
rapid bronchodilation
What are types of SABAs?
albuterol and levalbuterol
What is the delivery of SABAs?
inhaler or nebulizer, depending on formulation
What is the MOA of SABAs?
relax bronchial smooth muscle for rapid symptom relief
What do SABAs not control?
underlying airway inflammation
What should be assessed when taking SABAs?
respiratory response
What should be monitored when taking SABAs?
tachycardia, palpiations, tremor
What requires reassessment for SABAs?
increasing reliever use or reduced relief
What are types of inhaled corticosteroids?
fluticasone, budesonide, beclomethasone
What is the delivery of inhaled corticosteroids?
inhaler; selected formulations also use a nebulizer
What are inhaled corticosteroids?
reduce inflammation and help prevent exacerbations
What is the result of an ICS alone?
does not rapidly relieve bronchospasm
What is education when taking inhaled corticosteroidss?
rinse and spit after use; inspect the mouth daily
What is oral cadidiasis risk?
report white patches or coating lesions, or persistent soreness
What are LABAs and combination inhalers?
used for asthma
What are types of LABAs and combination inhalers?
budesonide-formoterol and salmemotrol/fluticasone; delivered by inhaler
What are LABAs?
provide prolonged bronchodilation
What is the result of certain prescribed ICS-formoterol regimens?
provide maintenance and/or relief
What is important to know about LABAs/ICS?
not every inhaler is a reliever
What are types of leukotriene modifiers?
motelukast and cromolyn
What is the delivery of leukotriene modifiers?
taken orally
What are leukotriene modifiers?
block leukotriene effects that contribute to inflammation and bronchoconstriction
What are leukotreine modifiers used for?
prevention and ongoing asthma control
What are leukotreine modifiers for ongoing control?
take once daily as prescribed, even when well
What is important to note about leukotriene modifiers?
not PRN treatment for an acute asthma attack
What must be reported for leukotriene modifiers?
mood, behavior, sleep changes
What is the role of ipratorpoum inhaler or nebulizer?
additional bronchodilation during selected exacerbations
What is the nursing emphaiss for impratoropium (inhaler or nebulizer)?
assess repiratory response
What is the role of selected LAMAs inhaler?
add-on maintenance treatment
What is the nursing emphasis of selected LAMAs inhaler?
not a rescue treatment
What is the role of systemic coritcosteroids (oral or IV, by drug)?
reduce inflammation during significant exacerbations
What is the nursing emphaiss of systemic corticosteroids (oral or IV, by drug)?
monitor glucose, mood/sleep, and infection
