This type of nebulizer generates aerosol on inspiration and nebulization stops when a patient’s inspiratory flow decreases below threshold.  It eliminates waste of medication, increases delivered dose threefold and reduces contamination of environment during expiration. Breath Actuated.png 

All of the following factors affect aerosol delivery by small volume jet nebulizer except:

A patient is receiving O2 through a nonrebreathing mask set at 8 L/min with an SpO2 of 85%.  You notice the mask’s reservoir bag collapsed completely before the end of each inspiration.  Which of the following actions is appropriate in this case?

One criterion for the use of a dry-powder inhaler (DPI) is the patient’s ability to :

A common application of the adjustable pressure-reducing valve is in combination with which of the following?

Match the following to the appropriate device or patient scenario:

A heated humidifier is delivering 100% body humidity to a patient’s airway. What volume of water is being delivered?

Which nebulizer generates aerosol continously and incorporates one-way valves that open on inspiration and close on expiration? Breath Enhanced.png

All of the following you would recommend bland aerosol therapy administration except?

A patient is receiving 40% oxygen via air entrainment mask.  The flowmeter is set on 12 L/min.  What is the total flow?
