A system (10) configured to facilitate humidification of a pressurized flow of breathable gas delivered to a subject (12) comprises a pressure generator (14), a nebulizer (16), a heater (38), one or more hardware processors (22), and/or other components. The pressure generator is configured to generate a pressurized flow of breathable gas for delivery to an airway (24) within a trachea of the subject. The nebulizer is configured to provide fluid droplets (54) to the breathable gas. The heater is configured to heat a volume of the breathable gas before the droplets are supplied to the breathable gas. The breathable gas received by the subject exhibits a target temperature and humidity level at short distance d from the nebulizer due to one or more of a number of the droplets, an average size of the droplets, a gas flow rate, and/or an amount of heating power.
