Which oxygen delivery device can deliver 40-60% FIO2 and is from 5-8 L/min?

Nasal cannula

Simple face mask

Aerosol mask

Face tent

Answer and Explanation

The Correct Answer is B

A: A nasal cannula delivers a lower concentration of oxygen, typically between 24-44% FIO2, and is used at flow rates of 1-6 L/min. It is not suitable for delivering 40-60% FIO2.

B: A simple face mask can deliver 40-60% FIO2 at flow rates of 5-8 L/min. It covers the nose and mouth, providing a higher concentration of oxygen compared to a nasal cannula.

C: An aerosol mask is used for delivering humidified oxygen or medications via nebulization. It can deliver varying concentrations of oxygen but is not specifically designed for 40-60% FIO2 at 5-8 L/min.

D: A face tent is used for patients who cannot tolerate a mask, such as those with facial trauma or claustrophobia. It provides humidified oxygen but does not deliver a precise FIO2 concentration.
