摘要：
An apparatus can include a nasal cannula assembly, which includes a face piece. The face piece includes a plenum portion and a nasal interface portion. The plenum portion is configured to be coupled to a supply line and defines a flow path configured to receive an aerosol flow from the supply line. The nasal interface portion includes a first delivery protrusion and a second delivery protrusion. The first delivery protrusion is configured to convey a first portion of the aerosol flow to a first nostril, and the second delivery protrusion is configured to deliver a second portion of the aerosol flow to a second nostril. The plenum portion includes a sidewall having a curved surface configured to redirect the second portion of the aerosol flow towards the second delivery protrusion. The sidewall is configured to isolate the flow path from a volume downstream from the second delivery protrusion.
