Resp Disorder 2 Flashcards
can asthma pts exercise
yes, uses SABA before
describe what a peak flow meter is
-highest air flow at forced expiration
-2 times a day when asthma is controlled
*establish normal baseline
(green/good, yellow/reliever drug, red/serious emergency d/t obstruction)
what are the drug therapy methods for asthma
preventative, rescue, combo
- adrenergic (Albuterold)
- steroids (inhaled unless for maintenence)
- theophylline (not used very often d/t SE)
- anticholinergic- dry pt up
describe the asthma rescue drugs
- given d/t active asthma attack
- ***SABA (short acting beta agonist)- first line, acts as bronchodilator (Albuterol)
- Anticholinergics- take longer to work
describe effect of steroids when they are inhaled
inhaled causes fewer side effects, not going through whole body
what are the asthma preventative/maintenance drugs
- ICS: inhaled corticosteriods- decrease inflammatory response
- LABA: inhaled long acting beta agonist (Solumedrol)
- leukotriones (singulair)- not inhaled
why do we want to hear wheezing during an asthma attack
means that air is getting in and out (even though its with difficulty)
*if there is no sound, may have complete air obstruction
most severe form of asthma
severe, life threatening complication of asthma attack
status asthmaticus
describe what occurs in status asthmaticus and what it can lead to
hypoxemia worsens
expiratory rate and volume decrease
may lead to rep failure or irreversible emphysemia
what does status asthmaticus require
requires intubation and ventilator support
leading cause of death worldwide
lung cancer
what is the survival rate of lung cancer and main cause
survival rate is r/t staging and degree
cigarette smoking is cause
*more women die of lung than breast cancer
primary and secondary prevention of lung cancer
primary: decrease smoking
secondary: screening (done early if avid smoker)
lung cancer manifestations
nonspecific, appear late in disease process
dependent on type of lung cancer
extensive metastasis BEFORE symptoms appear
persistent cough (productive or not)
chest pain
dyspnea
diagnosis of lung cancer
biopsy is most definitive
chest x ray
arterial blood gas (ABG) study
when is a cure for lung cancer more likely
stage 1 or 2
stage 3 or 4 cure is more rare
