The home care nurse is assessing a patient who requires home oxygen therapy. What criterion indicates that an oxygen concentrator will best meet the needs of the patient in the home environment?
A) The patient desires a low-maintenance oxygen delivery system that delivers oxygen flow rates up to 6 L/min.
B) The patient requires a high-flow system for use with a tracheostomy collar.
C) The patient desires a portable oxygen delivery system that can deliver 2 L/min.
D) The patient's respiratory status requires a system that provides an FiO2 of 65%.
Ans: C
Feedback:
The use of oxygen concentrators is another means of providing varying amounts of oxygen, especially in the home setting. They can deliver oxygen flows from 1 to 10 L/min and provide an FiO2 of about 40%. They require regular maintenance and are not used for high-flow applications. The patient desiring a portable oxygen delivery system of 2L/min will benefit from the use of an oxygen concentrator.
