B)Face mask
C)Nasal cannula
D)Nonrebreathing mask

Question

Quizplus · Accepted Answer

Oxygen can be delivered via the nasal cannula at flow rates of 1 to 2 L per minute,which deliver 24% to 28% FiO? 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 FiO? 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.
