Results Six trials (n = 491) met criteria for inclusion. Patients who received b-agonists by MDI+VHC showed a significant decrease in the admission rate compared with those by nebulizer (OR, 0.42; 95% CI, 0.24-0.72; P = .002); this decrease was even more significant among children with moderate to severe exacerbations (OR, 0.27; 95% CI, 0.13-0.54; P = .0003). Finally, measure of severity (eg, c...

The typical setup for administering volatile anesthetics to laboratory rats does not provide for humidification of the inspired gases, although it is known that failing to provide humidification can lead to airway inflammation and impaired pulmonary function during prolonged experimental protocols. We developed a simple humidification system in which a nebulizer was inserted into the nonrebreat...

A typical electrothermal vaporization (ETV) using a tantalum was built for low-pressure ICP-AES. The analytical performance of the ETV was tested and compared with that of a PFA pneumatic nebulizer with a double membrane desolvator (DMD). The limits of detection of the ETV were obtained in the range of 3.4 ng to 758 ng for Zn, Cu, Co, Fe, and Mg, while those of the PFA nebulizer were in the ran...

A twin six-port valve with two sample loops was installed between the autosampler and the nebuliser of a simultaneous inductively coupled plasma-atomic emission spectrometer. The valve was mounted close to the nebuliser inlet so that the time required for the sample to enter from the loop to the nebulizer was less than 0.5 s. The content of one loop was introduced to the nebulizer using a peris...

Background Guidelines recommend that patients presenting with acute severe asthma with life-threatening features receive the necessary high doses of b2-agonists via the nebulized route.The SideStream Plus (SS+; Philips Respironics) is a breath-enhanced nebulizer designed to maximize respirable output, while minimizing treatment time [1]. Prior to the introduction of a new version of nebulizer, ...

We studied the frequency of malfunction, variability in rate of nebulization, and effect of this variability on aerosol particle size of eight disposable jet nebulizer models produced by six manufacturers. Four of eight models showed visual signs of malfunction, including spraying of large, individually visible droplets, leaking of nebulizer solution, and air leaks that completely prevented neb...
