Many types of aerosol devices for delivering inhaled therapeutics are available for treating mechanically ventilated patients. Each type of device has advantages and disadvantages, which are discussed in this article. Many variables must be accounted for to optimize the technique of delivery and the amount of medication administered. It begins with choosing the right device based on the medication to be administered, knowing what particle size will be produced over what period of time, then determining how aspects of mechanical ventilation will affect medication delivery and deposition. Intermittent versus continuous nebulization, the nebulizer type, the type of spacer and its electrostatic charge, and the aerosol device’s position in the ventilator circuit all affect the efficiency of aerosol delivery. Ventilator parameters, including flow rate, pressurization, and features like the presence of a heat-moisture exchanger also affect medication delivery. In addition, correct patient positioning can improve treatment efficacy and response.
