In the context of oxygen delivery, what advantage does a nasal cannula offer?

1. Delivers high concentration of oxygen

2. Well tolerated and allows for eating and drinking

3. Used for patients needing full respiratory support

4. Provides higher pressures to assist breathing

The correct answer is: Well tolerated and allows for eating and drinking

The nasal cannula offers the advantage of being well tolerated while allowing patients to eat and drink. This is particularly important in a clinical setting where patient comfort and the ability to maintain normal activities are prioritized. The design of the nasal cannula keeps the patient's mouth free, making it easier for them to consume food or liquids without interruption, which is a significant benefit compared to other oxygen delivery systems like masks that can impede such activities. While the nasal cannula does deliver oxygen, it typically provides a lower concentration of oxygen compared to other devices designed for higher concentrations. It is not suitable for patients needing full respiratory support, as it does not provide the same level of oxygenation or pressure as devices like non-rebreather masks or mechanical ventilators. Lastly, it does not deliver higher pressures; rather, it delivers oxygen at ambient pressure, making it suitable for mild to moderate respiratory distress rather than severe cases requiring increased pressure to assist breathing.
