A new endeavor for me. Any thoughts/ advice on
acquiring a YAK 18T. What is required for import to
the USA? There are some for sale in Eastonia, Ukrane,
and Lithuania. It seems like a great airplane and I
would like the challenge of getting one if reasonable
possible.
Thanks

Hi
Anybody on the European(or anywhere else) side, have any ideas on suitable autopilots
.Have to be certificated to Hungarian standard.Have looked on the Hungarian
caa site but they dont seem to have an English language version,so I have
no idea if they list any.Any Hungarian speakers out there,or any 18t owners on
the HA reg with an autopilot?

| Subject: | Breathing Clean Air - Masks? |
Hi Doc,
I have also been thinking of scooping fresh outside air and connecting
my
mask to the pick up but since reading your post am having doubts.
I was working on my boat yesterday and as I always do got out my 3M
filtered
mask out and readied it for the job ahead when your post sprang to mind.
When I looked at the mask it looked very similar to my MBU-20/P but
obviously without the hose and with the filter elements. But internally
they
are very similar to each other with inlet and outlet valves etc. If what
you=92re saying is correct then the very same condition which occurs
with the
flying mask should indeed happen with the particle mask.
The only exception I can see would be if the inlet valve was to leak
back
into the inlet pipe then you=92d have the same re-breathing situation as
if
you were using a long swimmers snorkel.
So if your mask and valves were to be in good working order do you still
think it unadvisable to use it?
Please excuse my ignorance and Thanks for your input.

Subject: Re: Yak-List: Breathing Clean Air - Masks?
Rich was correct. Your were rebreathing your own air. Approximately 19%
of
the exhaled air is O2. 40% is C02. The rest is nitrogen and inert
gases.
Without having a fresh air source, you were entraining about 15-20% of
your
exhaled air. If you had taken your blood gas during this exercise you
would
have seen a minimal drop in your Pa02 (partial pressure of oxygen) and
a
increase in your PaC02. Ovetime, you will increase your PaC02 from a
normal
of 40 to 58 to 60% in an hour of doing this rebreathing. Yes the Air
Force
and Navy Aviators mask have a flapper valve that pops open when you
exhale
increasing the ambient pressure in the mask. The problem is some of that
exhaled air is vented into the fresh air line. Without a fresh gas
source
you will rebreath a precentage of your concentrated exhaled air. The
fresh
air source dilutes that concentration. The problem with accumulation of
CO2
is that it eventually acts as a narco tic along with cause some other
bad
physiological things like dysrythemias, siezures, and generalized system
hypoxia at high enough concentration. We actually do closed circuit
anesthesia to preserve the loss of body heat, on long cases. We use soda
lime (sodium hydroxide, potassium hydroxide, and an indicator, calcium
and
sodium silica in small amounts) or Baralyme as a scrubber to absorb the
C02
from the circuit. We supply fresh 02 to the circuit though so that the
O2
concentration does not drop to low. We follow serial blood gases to
monitor
the Pa02 and PaC02 along with other things during the surgery. While you
are
sucking on rubber, none of that monitoring is taking place nor is it
practical.
But to finish this episle, breathing your own exhaled air for a period
of
time is not good for you. I personally would not recommend just using
the
aviators mask and hose without a fresh air source. Particularly if you
smoke, have smoked, or have a respiratory disease like asthma or COPD.
And
yes, the FAA does let people with respiratory diseases fly based on
certain
tests that I am not going into now. but sucking rubber without a fresh
air
source is not good for you.

| Subject: | Breathing Clean Air - Masks? |
Lance,
The issue you face with using the aviator's mask without a fresh air source is
related to dead space air. The hose on the aviator's mask is is about 18 to 24
inches long. So each time you exhale you push air high in C02 down that hose.
Now when you take a breath, you suck that air back in. Then you repeat the process
when you again. This process is known a entrainment. There is a push pull
action taking place in the hose. If regular respiration takes place without
something diluting it out like sticking it out into the wind stream (pressure
breathing per say), the PC02 in the hose will gradually become equal the PC02
of your exhaled air. So over time you would gradually see a rise in your arterial
PCO2, With that long hose hanging off the mask that you are breathing through
you have increased dead space of your airway. Dead space is defined as that
part of the air way that is not involved in gas exchange. So your mouth, nose
(nasopharynx), trachea, and the first branch of the
Bronchi (primary bronchus) are all what is considered dead space. Now that you
have added that extra 2 feet of dead space to your airway, your are increasing
your work of breathing and that will result in an increase in your exhaled
PC02 also. There some other factors that I could bore you with relating to the
pressure differential between alveolar PC02 at inspiration verses exhalation
ect. In other words, the blood arriving at the alveolus (the site of gas exchange
in the lung) is high in CO2 (the Pulmonary Artery- the only artery in the
body that is higher in C02 the a vein, Pulmonary Vein). The freshly inspired
air is low in C02 and high in 02. So there is a pressure gradient that exist in
the alveolus verses the pulmonary artery. So C02 diffuses easily from an area
of higher concentration to lower concentration. Now if you keep sucking fresh
air into your alveolus that is high in C02, then you do not get the diffusion
of C02 out of your blood stream. So there is gradua
l increase in the PAC02 in your blood. Then all the I talked about in the other
post starts to take place.
The 3M mask does not present that problem. If it is the version that I am thinking
about. It has one or two screw in filters on either side of the rubber mask.
Some have a single filter on one side. Even though you will see a slight increase
in the PC02, it will be pretty much negligible. The filters on the mask
are designed to be very porous so as to facilitate elimination of exhaled gases
and decrease work of breathing by not offering alot of resistance to inspiration.
Measuring end tidal C02 in the mask does not show a significant increase
in C02 in that type of mask in the studies I have seen in the Occupational
Medicine texts. That mask can be hot as hell to wear but it is safe to use though.
I don't think you have a lot to worry about with the 3 M mask.
Hope this helps alleviate your concern about the 3 M mask,
Doc
