High-flow nasal cannula (HFNC) systems employ different methods to provide aerosol to patients. This study compared delivery efficiency, particle size, and regional deposition of aerosolized bronchodilators during HFNC in neonatal, pediatric, and adult upper-airway and lung models between a proximal aerosol adapter and distal aerosol circuit chamber. ⋯ The inhaled lung dose was low (1-5%) during HFNC. Approaches that streamline aerosol delivery are needed to provide safe and effective therapy to patients receiving aerosolized medications with this HFNC system.

A mechanical insufflation-exsufflation (MI-E) device is a commonly used tool for airway clearance in children with an ineffective cough. Whereas the device has been shown to have multiple benefits, limited evidence exists regarding parents' experiences with its home use in the Canadian context. This study's objective was to explore the perspectives and experiences of parents who receive service through the IWK Health Centre and use an MI-E device at home with their child. ⋯ Participants provided detailed descriptions of their journey from learning to integrating the MI-E device into their child's daily routine and family life. Its multiple associated benefits improved the child's and their family's quality of life. However, better education on its use was highlighted as a need for both parents and the health care professionals who work with them.
