Question 4: What are the indications of humidity therapy?
Answer:
Upper airway edema, Croup, Epiglottitis, post extubation Edema, bronchial hygiene, sputum induction
Question 5: Define condensation?
Answer:
Change of state from a gas to a liquid, as with water vapor condensation
Question 6: What is cromolyn sodium used to treat?
Answer:
Prophylactic for asthma
Question 7: What is the mode of action for xanthines?
Answer:
Promotes smooth muscle relaxation
Question 8: How does a breath enhanced SVN work?
Answer:
aerosol continuously, system of one-way valves, minimize aerosol waste. Inspiratory vent allows patient to draw air through nebulizer chamber generating & containing aerosolized drug, inlet vet closes, Aerosol exits oneway valve, increase inhaled mass 50%
Question 9: With what devices are therapeutic aerosols generated?
Answer:
Atomizer, nebulizer Question 10: To ensure delivery of a proper drug dosage with a meter dose inhaler, what must be done to it before its use?
Answer:
The canister should be warm to head or body temperature, canister should be vigorously shaking Question 11: When using a metered dose inhaler without a holding chamber or a spacer, the patient should be instructed to fire the device at what point?
Answer:
Immediately after beginning a slow inspiration
Question 12: Add high flow rates, what do you some bubble humidifiers produce?
Answer:
Aerosol particles
Question 13: What are the two main types of nebulizers?
Answer:
Jet/SVN; ultrasonic Question 14: Which type of humidifier traps the patient's body he ate expired water vapor to raise the humidity of the inspired gas?
Answer:
Heat moisture exchanger Question 15: What is the primary fate of inhaled aerosol particles that are between 1 and 0.5 µm?
Answer:
Most are clear during exhalation
Question 16: What are the effects of stimulating the beta one receptor site?
Answer:
Increased heart rate, increased force contractibility
Question 17: What type of humidifiers are used in clinical practice?
Answer:

Question 18: What is the action of cGMP?
Answer:
Promotes bronchoconstriction Question 19: What are the adverse affects that can occur with aerosolized steroids?
Answer:
Greater expense then oral, not helpful in status asthmaticus, increased risk of infection Question 20: What technique will increase aerosol deposition of small particles?
Answer:
10 second breath hold
Question 21: A heat moisture exchanger has an efficiency rating of 80%. What does this mean?
