The home care nurse is assessing a patient who requires home oxygen therapy. What criteria indicate 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 liters per minute.
B) The patient requires a high-flow system for use with a tracheostomy collar.
C) The patient desires a portable oxygen delivery system that delivers 2 liters per minute.
D) The patient's respiratory status requires a system that provides an FiO2 of 50%.
Ans: C
Feedback: The use of oxygen concentrators is another means of providing varying amounts of oxygen, especially in the home setting. These devices are portable, easy to operate, and are cost-effective. Oxygen concentrators require more maintenance than tank or liquid oxygen systems and generally do not deliver oxygen flow rates in excess of 4 liters, which provides an FiO2 of about 50%. The patient desiring a portable oxygen delivery system of 2 liters per minute will benefit from the use of an oxygen concentrator.
