Factors Affecting the Deposition and Output of Jet Nebulizer
Various technical, patient related and physical factors have been considered which provide impact on the penetration
and deposition of aerosols generated by jet nebulizers [41-49]. These factors are depicted in table 2.
Clinically important characteristics of Jet nebulizers
Clinically important characteristics of nebulizer performance is respirable dose provided for the patient, determined
by mass output of nebulizer and size of the droplet that are produced. Other important characteristics of nebulizer
performance include nebulization time, cost ease of use and requirement for cleaning and sterilization. A short
nebulization time that delivers and effective dose is desirable. Many nebulizers are low cost, mass produced, singlepatient-
use devices [50-53]. For delivery of an expensive medication, a nebulizer bowl may be most desirable, even
if the delivery rate in not maximal. Commercially available jet nebulizers, all with the same initial fill, and all driven
by the same air compressor, varied greatly in total delivery of fluid, the time required to deliver this fluid, and
percent of the delivered fluid in the respirable range. [54-57].
