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...

BACKGROUND The effectiveness of aerosol drug delivery during mechanical ventilation is influenced by the patient, ventilator, and nebulizer variables. The impact of nebulizer type, position on the ventilator circuit, and bias flow on aerosol drug delivery has not been established for different age populations. OBJECTIVE To determine the influence of nebulizer position and bias flow with a jet...

Due to the lack of information on this topic, the Educational Group of the Italian Association of Hospital Pneumologists performed an open, multicentre, observational survey to evaluate home nebulizer practices in Italy. From May-December 1999, all patients attending one of the 27 participating chest clinics throughout Italy and who were or had been using a home nebulizer in the previous 6 mont...

Most physicians and respiratory therapists are knowledgeable of the use of aerosolized drugs, but many are less familiar with the performance characteristics of the nebulizer. In fact, the general opinion is that the performance of the nebulizer is relatively unimportant. However, there is accumulating evidence that the nebulizer itself does make a difference. The decision to replace a good per...

BACKGROUND The Acapella device produces high-frequency oscillations and positive expiratory pressure to promote bronchial secretion clearance. Its performance during aerosol delivery has not been described. We evaluated the effect of nebulizer and Acapella configuration on pulmonary deposition of radio-tagged aerosol in healthy subjects. METHODS Ten healthy male subjects (mean age 24.4 ± 2.2 ...

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 ...

BACKGROUND Measurement of nebulizer medication adherence that relies on self-report of medication use is subject to recall bias and increased patient burden. Electronic monitoring of nebulizer medication use is relatively new technology and provides an objective measure of nebulizer use. OBJECTIVE To examine levels of agreement for nebulizer use between self-report on diary cards and electron...

Increased delivery of aerosol to a model lung (attached to a mechanical ventilator) has been demonstrated with an ultrasonic nebulizer as compared to a jet nebulizer. This study examined whether the increased aerosol deposition with an ultrasonic nebulizer could also be demonstrated in vivo. Seven patients (6 male and 1 female) were studied during mechanical ventilalion (Siemens Servo 900C, Mid...

The Agilent OneNeb nebulizer is a novel nebulizer design that offers superior performance compared to other commercially available concentric nebulizers used with ICP-OES instruments. This universal nebulizer provides improved sensitivity, greater tolerance to dissolved salts, and is inert so it is suitable for use with strong acids such as hydrofl uoric acid (HF) and most common organic solven...

BACKGROUND This study was conducted to compare the efficiency of jet nebulizers, vibrating mesh nebulizers, and pressurized metered-dose inhalers (pMDI) during assisted and unassisted administration techniques using a simulated spontaneously breathing pediatric model with a tracheostomy tube (TT). METHODS An in vitro breathing model consisting of an uncuffed TT (4.5-mm inner diameter) was att...
