At a flow rate of 6 L/min, a nasal cannula can deliver an approximate oxygen concentration of up to: 44%
<h3>How to calculate the oxygen concentration?</h3>
We are given;
Flow rate of Nasal Cannula = 6 L/min
Now, from research we know that Nasal cannula delivers oxygen concentrations of approximately a minimum of 24% to a maximum of 44% at flow rates of a minimum of 1 L/minute to a maximum of 6 L/minute in adolescents and adults.
Now, since the flow rate we are given is a maximum of 6 L/min, then we can say that the approximate oxygen concentration is 44%.
