A patient with COPD has carbon dioxide retention and is ordered oxygen therapy. The nurse anticipates the use of which oxygen delivery system?
a. Face tent
b. Face mask
c. Nasal cannula
d. Nonrebreathing mask
C
Oxygen can be delivered via the nasal cannula at flow rates of 1 to 2 L per minute, which deliver 24% to 28% FiO2 and are useful for patients with chronic lung disease. The face tent is used primarily for humidification and for oxygen only when the patient cannot or will not tolerate a tight-fitting mask. The FiO2 cannot be controlled, and there is no way to estimate how much oxygen is delivered. The simple face mask is used for short-term oxygen therapy. It fits loosely and delivers oxygen concentrations from 40% to 60%. The mask is contraindicated for patients with carbon dioxide retention because it will make the retention worse. When used as a nonrebreather, the plastic face mask with a reservoir bag delivers 60% to 100% oxygen at appropriate flow rates. This oxygen mask maintains a high-concentration oxygen supply in the reservoir bag. If the bag deflates, the patient breathes in large amounts of exhaled carbon dioxide.
