Respiratory 1 Flashcards
What is asthma
intermittent and reversible airway obstruction releated to inflammation and airway hyperresponsiveness -
what age does asthma occur
can occur at any age
what are the manifestations of asthma
hypertrophy, edema, thick mucus, bronchoconstriction
what is athma health promotion
stop smoking, decrease exposure to irritants, get vaccines, avoid triggers, teach how to use meds, regular exercise, hot water to wash sheets
what do ABGs look like for someone with asthma
hypoxemia = less then 80
early in attack = hypocarbia = PaCO2 less then 35, Late in attack = hypercarbia= PaO2 over 45, increased ETCO2
how to confirm asthma with pulmonary function test
if measurements increase by 12% after treatment with bronchodilator, pts usually have 15-20% decrease in one of FVC, FEV, PEA, airway responisveness
Asthma risk factors
family history, smoking (2nd hand too), environmental allergies, chemical irritants, GERD, older adult
Respiratory changes in older adults
decrease pulmonary reserve, more susceptible to infection, decrease sensitivity to beta receptors causes an increased risk for bronchospasms
diagnostic imaging for asthma
chest X-ray, immunoglobulin
SS of asthma
wheezing on exhale, cough, mucus production, increased respirations, accessory muscle use, barrel chest, cyanosis, decreased SP O2, hypoxemia increased heart rate
what changes are seen in eosinophils with asthma
increased with allergies too
what will you find in a sputum culture for asthma
curshman spirals
what is the treatment goal for asthma
to control asthma, guided self-care patient active and managing their care
what is an individual asthma action plan
developed by patient and PCP, tailored to meet personal triggers, asthma symptoms, and drug response
what is intermittent asthma classification
signs and symptoms less than two days a week
what is mild persistent asthma classification
signs and symptoms over two days a week
what is persistent asthma classification
signs and symptoms daily
what is severe asthma classification
signs and symptoms continuous
what is the nursing care for asthma
position for maximum ventilation, give O2, monitor heart, initiate IV, provide rest, teach infection prevention, encourage vaccinations
what are asthma symptoms of determining control
daytime wheezing, dyspnea, coughing more than two times per week, waking from sleep with wheezing/dyspnea/coughing, rescue drug used over two times per week, activity limited or stopped by symptoms over two times weekly
what are some complications that can occur from asthma
respiratory failure caused by persistent hypoxemia related to asthma
what is the hospital admin criteria for an acute asthma attack
FEV1 = less than 30% of predicted no improvement in one hour
what is the SS for an acute asthma attack
respiratory distress at rest, difficulty speaking, diaphoresis, accessory muscle use, respirations over 30, heart rate over 120
what are the signs and symptoms of an emergency asthma attack
absent breath sounds, cyanosis, inability to lie down, abdominal breathing
