Default What are the dangers of too much CPAP pressure? (heart)


Excuse my ignorence, I am inexperienced in CPAP thingys, but I have a
RES MED S7 on a months patient trial, after the first week I came to
the conclusion it was not providing as much benifit as the first
machine I had for a weekend. This was supposed to calculate my
pressure requirement but because of mask leakage gave inconclusive
results and my clinician set the resmed at 8, commenting that I may
have to have it increased to 10. Getting in touch with the hospital I
find she is on a weeks holiday, and there is no one else qualified to
change the pressure...Can anyone please advise me, what are the
problems/dangers of setting the pressure too high. I am an overweight
Asmatic male, age 52 with no other heart or BP problems. It would also
be useful to know how to reset the pressure to make the most of this
trial. BTW I am in the South East UK being treated under NHS hospital
after referal from doctor and one nights sleep study.

Thank you

Andy

Too much pressure can (among other things?) trigger/increase
central apneas. Not a good thing.

Default What are the dangers of too much CPAP pressure? (apnea)


Too much pressure can result in death. No joke. Central apnea is a result,
which means that your brain decides you don't need to breathe, so you don't,
which causes your heart to stop, and removes your need for a CPAP
permanently.

Sarcastic? Maybe. Am I trying to get the point across? Definitely.

It is not good to be on the wrong pressure, but if one must be wrong, it is
better to be under than over, as minimally as possible.

Dhorwitz...could you please expand to me what a "central apnea" is and
how it differs from normal/(abnormal?)

Default What are the dangers of too much CPAP pressure? (apnea)


In article <43e9b5c2.0310280458.6db457a3@posting.google.com>,
andy@andycabs.com says...


"Normal" or Obstructive apnea is the more common blockage-induced type.
This is the one us fat busturds get from too much of us surrounding the
air-ways- although there are plenty of skinny busturds with the same
problems; we not only outweigh them, but probably outnumber them as well
<BFG>.

Central refers to a "glitch" in the Central Nervous System where the
brain forgets to send a signal to breathe. Not quite as common, it can
happen while sleeping or in some cases (like me) whilst awake. Central
Events can be triggered by overpressure of a xPAP, drugs, sound, certain
frequencies (colors) of light, specific frequency of pulsating light, or
for no reason at all. I only know of the connection with sound and light
as I can 'force' a central event in myself with specific sounds and/or
lights.

Default What are the dangers of too much CPAP pressure? (barotrauma)


I have never read on this newsgroup (or elsewhere) of anyone
actually suffering barotrauma or increased lung inflammation
from a commercially built CPAP made for home use. I mentioned it
only as a *theoretical* possibility which has been discussed on
this newsgroup, perhaps another good reason not to jack up CPAP
pressure higher than what is prescribed. Unlike some
ventilators, respirators, and anesthesia machines, CPAPs do not
force breathing, but work only to keep the airway open while the
user breathes on his own. CPAP masks also have unsealable
outlfow vents that prevent accidental build-up of pressure.

Default What are the dangers of too much CPAP pressure? (weight)


Andy

Why don't you consider getting one of the Resmed Autoset Spirit
machines.

These are purchasable directly from Resmed with a prescription from
your consultant. This also exempts you from VAT.

The whole issue of pressure becomes a non-issue because the machine
automatically adjusts to the pressure that you need. This varies
over time with various factors such as weight and the position that
you are lying in bed. The machine detects when hypopnoea and apnoea
events as well as snore are occurring and ramps up the pressure to
deal with them. It then reduces slowly over some minutes of not
needing such high pressure. On a fixed pressure machine, I would
need approx. 11cm H20 to deal with the majority of events, but in
reality, during the course of a typical night, for most of the time
only 6-7 is needed and with occasional peaks.

This makes for much more comfortable use of the machine and not
needing to worry about messing around with pressure. Also, there is
an optional heated humidifier which plugs onto the front of the
machine and also adds to the comfort of use for many people.

I tried one of the S7 machines for a bit and although it was OK, the
automatic adjustment of the Spirit makes for a much better experience.

Thanks for bringing that up, I remember it now.

Also good to see Doug again, even if is from an archive.
