Unit 4 Flashcards
(164 cards)
What is the difference between ventilation, transport, and perfusion
Ventilation—process in inhalation 02 and exchange CO2 (BREATHING)
Transport—ability of O2 to be carried via Hg (CELLS)
Perfusion—blood volume, pump, vascular tissue which allow blood to be carried to tissues (Vessels—>Tissue)
What is the function of elastin
Expand and contract lungs
What extrinsic and intrinsic factors of restrictive respiratory disease
Extrinsic (Outside Lungs)—Brain, Polio, Broken ribs)
Instrinsic (Inside lungs)—Pneumonia, Covid, pulmonary fibrosis
What are obstructive factors of respiratory disease
Asthma, airway collapse, less elastic tissue, poor exhale high residual volume (COPD)
T/F 25.3% of smokers are adults who live below poverty level
T
T/F largest percentage of non Hispanic American Indians of 31.8% smoke or use tobacco products
T
What do you see, hear, and measure adequate gas exchange
Effort of breathe RR
90-100% O2
Skin, nails, and lips are appropriate
Symmetry of chest
Clear breath sounds
What will we see if babies have impaired gas exchange
Poor feeding
What are physiological signs of impaired gas exchange
Tripod position
Adventitious lung sounds
Tachycardia
Altered LOC
What organ is most sensitive to oxygen deprivation
Brain
What is a bronchoscopy
Direct endoscopic exam to look and remove blockage
What is silent chest
Severe decreased breath sounds=severe obstruction
What is status asthmaticus
Asthma complication
Life threatening
Without treatment: hypotension, bradycardia, and respiratory arrest
Bronchdiators and steroids are ineffective
Treatment=intubated and mechanically ventilated
T/F with asthma, take dilator first, steroid second
T
What diagnostic testing is used to diagnose asthma
Allergy test
Peak expectorey flow rate (PEFR) >80%
Spiromatory
Serum level of immunity cells
Oximetry, ABGs
Chest imaging
What is a sort acting bronchodilator
Albuterol
“Rescue”
Take before: excerise
Side effects: tremors, tachycardia
NOT FOR LONG TERM USE
What is a long acting bronchodilator
Salmeterol
“Controller”
Used once every 12 hours
Decreases need for rescue inhaler
NEVER USE FOR AN ATTACK
What asthma drug can increase digoxin toxicity
Methylxanthines
What do corticosteroids
Decrease hyper responsiveness, block late phase, block migration in inflammatory cells
What is the side effects of Budesonide/fluticasone
Must be used on a fixed schedule
—oroparyngeal candidasis (thrush)—-rinse mouth
What are the three types of inhaled devices
Metered dose inhaler
Dry powered inhaler
Nebulizers
What is the technique for dry powder inhaler and challenges
Don’t shake
Rapid breath—hold 10 sec
Used when have less dexterity
Challenges: not all meds are available and cost effective
Keep out of high humidity
Rinse mouth
What are the challenges of nebulizers
Bacterial growth in equipment
What is green zone of action plans
Doing well: no symptoms, activity inc, PEFR >80%, med adherence
