Which oxygen delivery system is used for a patient requiring a high rate of oxygen?

The nonbreathing mask is specifically designed for patients who require a high concentration of oxygen. This system includes a reservoir bag that helps ensure that the patient receives a higher percentage of oxygen. It has one-way valves that prevent the exhaled air from mixing with the oxygen being delivered, allowing for the maintenance of a high oxygen concentration.

The nonbreathing mask can deliver oxygen flow rates ranging from 10 to 15 liters per minute, providing an oxygen concentration of approximately 60% to 100% to the patient. This makes it particularly effective for emergency situations or for patients experiencing severe respiratory distress, where maximizing oxygen supply is critical.

In contrast, other oxygen delivery systems such as the nasal cannula and simple face mask deliver lower concentrations of oxygen and may not be suitable for patients who need a high rate of oxygen. The Venturi mask, while used to deliver precise concentrations of oxygen, is not aimed at providing the high flow rates that the nonbreathing mask can deliver.
