Oxygen is delivered via the cannula at a flow rate from 1 to 6 L/min,which is useful for low oxygen concentration in patients with chronic lung disease.
The face tent is a shield-like device that fits under the patient's chin and sweeps around the face.It is used primarily for humidification and for oxygen only when the patient cannot or will not tolerate a tight-fitting mask.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.Frequently inspect the bag to make sure it is inflated.If it is deflated,the patient breathes in large amounts of exhaled carbon dioxide.
