In the current study, an inline breath-enhanced jet nebulizer was tested and compared in vitro with a vibrating mesh nebulizer on the humidifier dry\u2013inlet side of the ventilator circuit.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>Two duty cycle breathing patterns were tested during continuous infusion (5 or 10 mL\/h) with and without dynamic changes in infusion flow and duty cycle, or bolus delivery (3 or 6 mL) of radiolabeled saline solution.

During bolus treatments, IM increased linearly to plateau. IM variability was attributable to the duty cycle (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) (40%) and residual radioactivity in the nebulizer (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) (20%). Separate analysis revealed that the vibrating mesh nebulizer residual volume contributed 16% of the variability and inline breath-enhanced jet nebulizer contributed 5%. IM variability was independent of bolus volume (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.82) (1%).
