What determines the deposition of methacholine delivered by a nebulizer?

What determines the deposition of methacholine delivered by a nebulizer?

The expected pulmonary deposition of methacholine (delivered dose) for each concentration is calculated based on the time of inhalation, the particle size distribution (to estimate the respirable fraction), the rate of output and the respiratory duty cycle (TI/TTOT), which may be assumed to be 0.4 [87, 88].

What is the difference between a mesh nebulizer and a regular nebulizer?

Mesh nebulizers are more efficient than jet nebulizers and can provide higher drug doses to patients. Although human studies with mesh nebulizers are limited, in vitro studies demonstrated approximately 2-3 times higher lung deposi- tion with mesh nebulizers when compared to jet nebulizers (31,32).

Can you use budesonide in a mesh nebulizer?

The results demonstrated that both nebulizer types are capable of delivering solutions but that the ultrasonic nebulizer cannot effectively deliver budesonide, whereas the mesh nebulizer can.

Which is better inhaler or nebulizer?

Inhalers are smaller and require no power source. And because they deliver the medicine much more quickly than a nebulizer, they may be preferred by some parents. The age of the child also makes a difference in how an inhaler is used. Metered dose inhalers (MDI) are the most widely used, but they require coordination.
