    Aerosol devices and delivery methods for children requiring respiratory support.

    Abstract

    Many pediatric patients receiving aerosolized compounds require respiratory support. This can complicate compound delivery since most aerosol devices are not designed for use in conjunction with respiratory support devices. Common complications during delivery of aerosolized compounds to pediatric patients requiring respiratory support are an inconsistent and unpredictable delivered concentration of compound, altered airway deposition of the compound, and interference with the respiratory support device. This session will provide a review of techniques, devices, and delivery considerations for aerosolized compounds to pediatric patients requiring respiratory support.

    Respiratory care support devices include non-invasive oxygen delivery devices, non-invasive pressure delivery devices, and invasive ventilatory support devices. Typically, non-invasive oxygen delivery devices do not interfere with delivery of aerosolized compounds. Non-invasive pressure delivery devices include continuous positive airway pressure (CPAP) and bi-level positive airway pressure (BiPAP) and require integration of the aerosol device to the CPAP or BiPAP circuit, allowing bias flow to dilute and alter aerosolized compound deposition. Invasive ventilatory support devices can affect aerosol delivery in the same way that CPAP and BiPAP do; moreover, aerosolized compounds can negatively affect the function of these devices. Optimal aerosol device selection and techniques can overcome these issues.
