Abstract: Proposed devices operate on positive pressure with as little as 5-6 ml of air and can efficiently empty (emitted doses >80%) and deliver the aerosol to infant lungs (lung delivery efficiency of ˜60% of the loaded dose). Significant features include internal flow structure of the air-jet DPI, automatic gas sources, infant-specific interfaces, small diameter nasopharyngeal tubes, sealed nasal prongs, 3D rod array preceding patient interface, nasal CPAP rapid aerosol delivery system, nasal CPAP streamlined interface, multidose storage and delivery unit, and pressure sensing near the infant airways (at the nasal cannula interface).
