Efficacy of a prototype inspiratory-synchronized small particle versus conventional vibrating mesh nebulizer during pediatric and neonatal mechanical ventilation.

Background: An inspiration-synchronized vibrating mesh nebulizer (VMN) has been reported to improve aerosol delivery during adult mechanical ventilation. A prototype VMN generating smaller particles was developed. We aimed to compare the aerosol delivery efficiency of small-particle and conventional VMNs in inspiration-synchronized and continuous modes during neonatal and pediatric mechanical ventilation.

Effect of Interrupting Heated Humidification on Nebulized Drug Delivery Efficiency, Temperature, and Absolute Humidity During Mechanical Ventilation: A Multi-Lab Study.

During mechanical ventilation (MV), inspired gases require heat and humidification. However, such conditions may be associated with reduced aerosol delivery efficiency. The practice of turning off heated humidification before nebulization and the impact of nebulization on humidity in a dry ventilator circuit remain topics of debate.
