Jet and ultrasonic nebuliser output: use of a new method for direct measurement of aerosol output.
Output from jet nebulisers is calibrated traditionally by weighing them before and after nebulisation, but the assumption that the weight difference is a close measure of aerosol generation could be invalidated by the concomitant process of evaporation. A method has been developed for measuring aerosol output directly by using a solute (fluoride) tracer and aerosol impaction, and this has been ...
متن کاملRandomised crossover trial of salbutamol aerosol delivered by metered dose inhaler, jet nebuliser, and ultrasonic nebuliser in chronic lung disease.
AIMS To compare the efficacy of salbutamol delivered by metered dose inhaler (MDI), jet nebuliser, and ultrasonic nebuliser in ventilated infants with chronic lung disease. METHODS Twenty preterm ventilated infants with chronic lung disease were enrolled in two studies. In study 1 (n = 10), each infant was given 200 micrograms of salbutamol at 4 hour intervals and in random sequence from a me...
متن کاملVariability in aerosol output of the DeVilbiss 646 jet nebulizer.
Ten new jet nebulizers (DeVilbiss 646) were studied to determine their consistency of output. Each nebulizer, containing 2 ml of saline solution, was run for 1 min in triplicate at four different straw (capillary tube) positions, keeping all other variables constant. Total output in milliliters per minute and volume of aerosol in the respirable range (1.0 to 5.0 microns) were measured. There wa...
متن کاملUltrasonic Cardiac Output Measurement for Non- Invasive Cardiac Output Monitoring: Update and Lit- Erature Review
In this article, we review use and clinical utility of the Ultrasonic Cardiac Output Monitor, manufactured in Australia, which was first introduced clinically in 2001. It is non-invasive, requires only a low cost and allows for bedside examination, all of which make this tool potentially useful for patients in emergency departments and intensive care units. Its uses include triage, differential...

مفهوم فرضیه تولید اجباری سویین (1985)، بیانگر تسهیل یادگیری زبان دوم می باشد. این فرضیه پیشنهاد میکند که هنگامیکه دانش آموزان مجبور به شرکت در تولید زبان می شوند، این فرصت را دارند که پیامی دقیق، منسجم و مناسب را ارائه دهند. با توجه به کمبود تحقیقات کمی در جهت حمایت یا رد تولید اجباری، مطالعه حاضر اقدام به ایجاد داده های کمی جهت اثر تولید اجباری نموده است. هدف از این مطالعه از دو قسم می باشد. ا...
