Question 11 of 18

Yes. That response is right.

To determine the dose, first determine the tidal volume (in this case it is 6 because there were 3 liters of nitrous oxide and 3 liters of oxygen which totals 6).

The flow rate of the nitrous oxide (in this case it is 3 liters) is divided by 6 and then multipled by 100. This equals 50%.
