The physician has ordered your patient to receive continuous administration of heliox with racemic epinephrine secondary to postextubation stridor.
As you approach the bedside to deliver the ordered dose of racemic epinephrine via small volume nebulizer, what outcome should you expect with a gas flow of 10 L/min of heliox?
a. The nebulization time will be less than when using oxygen as a power gas.
b. The mass median aerodynamic diameter (MMAD) of the aerosolized medication will be greater than when using oxygen as a power gas.
c. There will be a twofold increase in nebulization time (compared with oxygen as a power gas).
d. The MMAD and nebulization time will remain unchanged.
Question 2
A 7-month-old infant presents with a diagnosis of respiratory syncytial virus. The attending physician agrees with your recommendation of ribavirin to treat the disease.
Because ribavirin is delivered as an aerosol, you must decide which method of delivery to use. Which of the following aerosol administration devices would you choose?
a. Small volume nebulizer
b. Large volume nebulizer
c. Dry powder inhaler (DPI)
d. Small particle aerosol generator (SPAG)
