A patient with asthma benefits from a precise preset FɪO₂.With a simple mask,there is a greater likelihood of the patient retaining CO₂,which is not helpful for those with asthma.Breathing through pursed lips is beneficial to people with asthma; however,it is not the first course of action.Finally,a high-flow cannula at 15 L/min is too much FɪO₂ for the patient at this time.
