Hi Garnet, I'd be interested in knowing how you - or whoever - arrived
at this conclusion, since the ultrasonic element seems to be about the
same in the one (only one) I've seen used for animals and the multitude
I've seen for humans.
My only point is that someone may have been trying to sell something on
the basis of an advertisement, not facts. Consider what either of
these
do; the ultrasonic part is to assure the carrier, water, and content
are
not separated by distillation, as in steam, and are effectively
delivered to the alveoli, not trapped in larger passageways as droplets
like the whirly bird (for want of a better description) type
humidifiers
make.
The idea that there could be a size of droplet that would be "too
small"
seems suspect, unless the idea was that the medication would be left
behind by being dropped out or evaporated out of the solution being
"nebulized" - which I think means "fogged". And if that were the case,
it would be useless for most of us warm-bloodeds. Most mammal lung
tissue is kinda similar when you are talking about the alveolar level -
has the same job, mainly getting CO2 out of the blood and O2 in; i.e.
packing an enormous area of very thin tissue in intimate contact with
the blood on one side and the atmosphere on the other into a reasonably
compact and protected flexible space.
Considering the minor cost of a used ultrasonic humidifier and the
minor
effort of cleaning and sanitizing it (what else is CS for, after all?)
why not set aside some presumed (dare I say "nebulous"? <g>)
theoretical
perfection in the interest of getting the job done; the proof's in the
results, not the ad copy.
One additional note; how many "nebulizers" does a veterinarian have to
have to treat the numerous mammalian and avian species that come
through
the clinic door? Give you a clue? Does me. . . .

The issue of droplet size is that there is an optimal size above or
below which the medication is not delivered deep into lung tissue.
Room humidifiers do not make the same size droplet as a nebulizer.
You can research the specs on droplet size or speak to someone
who sells various nebulizers and knows the specs.
It's been some time ago that I researched this for myself when I
was looking at purchasing a nebulizer and many on this list
were discussing adapting room humidifiers. If that is all you have
then it is better than nothing but an ultrasonic humidifier is not
equivalent to an ultrasonic nebulizer. That is my only point.
