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

Flow should be more than ____ L/min to prevent rebreathing CO2 and has an FiO2 rate of 35-50%

A	5
B	10
C	15
D	20

Explanation:

Detailed explanation-1: -Simple face mask provides an additional reservoir of 100-200mL of oxygen. It can provide a FiO2of up to 0.6 to the patient. The flow rate must be a minimum of 5 L/min to prevent rebreathing and prevent carbon dioxide (CO2) accumulation.

Detailed explanation-2: -FIO2 is typically maintained below 0.5 even with mechanical ventilation, to avoid oxygen toxicity, but there are applications when up to 100% is routinely used. Often used in medicine, the FIO2 is used to represent the percentage of oxygen participating in gas-exchange.
