A patient who was admitted with symptoms of hypoxia is changed from a face mask to a nasal cannula for oxygen delivery. The nurse realizes that this patient's condition is
1. deteriorating.
2. improving.
3. stabilizing.
4. compounded with another health issue.
Correct Answer: 2
Low-flow oxygen delivery systems include the nasal cannula, simple face mask, partial rebreathing mask, and nonrebreathing mask. A nasal cannula can deliver 24% to 45% oxygen concentrations with flow rates of 2 to 6 L/min. The nasal cannula is comfortable and does not interfere with eating or talking. A simple face mask delivers 40% to 60% oxygen concentrations with flow rates of 5 to 8 L/min. This patient's condition is most likely improving. There is not enough information to determine if this patient's condition is stabilizing or is compounded with another health issue.
