Physicochemical aspects and efficiency of albuterol nebulization: comparison of three aerosol types in an in vitro pediatric model.
BACKGROUND Advances in nebulizer design have produced both ultrasonic nebulizers and devices based on a vibrating mesh (vibrating mesh nebulizers), which are expected to enhance the efficiency of aerosol drug therapy. The aim of this study was to compare 4 different nebulizers, of 3 different types, in an in vitro model using albuterol delivery and physical characteristics as benchmarks. METH...
متن کاملAlbuterol delivery by 4 different nebulizers placed in 4 different positions in a pediatric ventilator in vitro model.
BACKGROUND The type of aerosol generator and the position in the ventilator circuit are crucial to determine aerosol delivery during mechanical ventilation. We compared lung deposition of albuterol aerosols generated by 4 different nebulizers placed in-line in 4 different positions in a pediatric ventilator model. METHODS Two brands of continuously operated jet nebulizer (6 L/ min, oxygen), a...
متن کاملAlbuterol delivery in an in vitro pediatric ventilator lung model: comparison of jet, ultrasonic, and mesh nebulizers.
OBJECTIVE To determine the influence of nebulizer types and nebulization modes on bronchodilator delivery in a mechanically ventilated pediatric lung model. DESIGN In vitro, laboratory study. SETTING Research laboratory of a university hospital. INTERVENTIONS Using albuterol as a marker, three nebulizer types (jet nebulizer, ultrasonic nebulizer, and vibrating-mesh nebulizer) were tested ...
متن کاملA comparison of commercial jet nebulizers.
Seventeen commercially available jet nebulizers from 15 commercial sources were studied (Acorn-I, Acorn-II, AquaTower, AVA-NEB, Cirrhus, Dart, DeVilbiss 646, Downdraft, Fan Jet, MB-5, Misty Neb, PARI LC JET, PARI-JET, Salter 8900, Sidestream, Updraft-II, Whisper Jet). All nebulizers were filled with 2 ml of saline solution plus 0.5 ml of albuterol and powered with the same source (DeVilbiss Pul...
متن کاملComparison of drug delivery from conventional versus "Venturi" nebulizers.
Attempts to improve drug delivery from conventional jet nebulizers have included the use of storage systems to reduce drug wastage during exhalation. Venturi nebulizers enhance drug delivery during inhalation, reducing treatment times and drug wastage. This study investigated the effect of age on inhaled dose from a conventional jet nebulizer (Acorn) used both with and without a storage chamber...
