Which method of oxygen delivery provides a continuous supply?

The method of oxygen delivery that provides a continuous supply is the tent. This system creates a controlled environment that can maintain a steady flow of oxygen to the individual inside. Oxygen tents are often used for patients who require a higher concentration of oxygen over an extended period, such as in certain respiratory conditions.

In contrast, a mask typically provides oxygen but may not maintain a continuous supply, as it can be removed or may have varying flow rates. A face shield is generally used for protection rather than for delivering oxygen. Supplementary oxygen usage can vary in delivery methods and flow rates, often depending on the device used, such as nasal cannulas or masks, which may not ensure a continuous supply. Thus, the tent is specifically designed to offer a more consistent and uninterrupted flow of oxygen for those requiring ongoing respiratory support.
