Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A non-rebreather mask has blocked ventilation ports and can deliver close to ____ of FiO2.

A	100%
B	90%
C	80%
D	70%

Explanation:

Detailed explanation-1: -Non-rebreather masks deliver oxygen at higher concentrations, up to 70% to 100%. This is important for people who have difficulty breathing or cannot get enough oxygen on their own.

Detailed explanation-2: -High-flow oxygen (HFO) consists of a heated, humidified, high-flow nasal cannula that can deliver up to 100% heated and humidified oxygen at a maximum flow of 60 LPM via nasal prongs or cannula. An air/oxygen blender can provide precise oxygen delivery independent of the patient’s inspiratory flow demands.

Detailed explanation-3: -The flow meter is connected to either a bottle of oxygen or a medical wall supply of oxygen. This oxygen is PURE, it is 100% oxygen! Therefore, anything that comes out of that flow meter has an FiO2 of 100%.
