Q:
How safe is the machine?
A: There are two safety
controls for temperature: a built in cut-off that prevents the stainless
steel heating plate from exceeding 128°C, and a sensor in the airflow
in the body of the machine which regulates the airflow to 55-60°C.
The heater plate heated by a plastic thermal ring on its underside is
light, clean, and similar to heaters used in aerospace. The water in the
container on the plate keeps the operating temperature of the plate below
118C. This low operating temperature contributes to its safe use.
Q:
What about bacterial/viral contamination?
A: The machine is self-sterilizing. The water in the container is maintained
above 80°C. Air exits from the machine at 50°C 28% relative humidity. These
conditions do not allow bacteria or viruses to survive. During the transmission
in the hose, the humidity graduates to 100% as the temperature falls to 30-34°C
at the mask. One machine can thus serve all members of the family, but each
member must have their own connections, hose, mask and filters. Bacterial/viral
filters should be changed weekly.
Q:
Have there been any complaints?
A: The
machine is not as quiet as some would like.
Others have complimented the machine on
inducing sleep. Without exception, using the machine will interrupt sleep.
After several hours use the body temperature rises, causing the user to throw
off the bedclothes. The ideal temperature at the mask should be 37°C. The
30-34 °C that the machine delivers is a compromise,
which allows uninterrupted sleep for 4 hours.The
water in the container will last 11-12 hours The mask is light and fits loosely,
so it is never a source of complaint.
Of course this is only an issue if you use it while sleeping. One could use
the machine continuously in any sedentary activity for 8-10 hours attending
to inevitable condensation only, every 3-4 hours.
Q: Is it OK to turn in my sleep during treatment?
Turning in sleep is normal.
The standard 4 foot hose regulates the temperature drop from the machine,
and is long enough to allow turning to any position in bed. The concertina
hose does not compress the airflow, and pulling on the hose releases its connection
so that the machine base will not be moved.
Q:
Can steam inhalation replace the SINUCLEAR?
A: Folks have advocated and used steam treatment for
hundreds of years with good effect. The SINUCLEAR
is really a modification of the steam inhaler to use in a controlled
unobtrusive manner. With the steam inhaler the temperature is uncontrolled,
liable to produce burn injury, and the water needs to be replaced at frequent
intervals. It is difficult to use for more than 30 minutes as one is bent
over the appliance in a sitting position unable to do anything except inhale
water vapour. The steam emission is enough to wet everything in sight. The
Rhinotherm machine made in Israel is also a modification of this principle.
With a 18 inch hose it delivers 100% humidified air at 52 °C.
which one inhales for 30 minutes twice weekly. It must be used in the upright
position, and because of the delicate controls, retails at approximately $600US.
Its purpose is not to rest the sinuses but is an adaptation of the treatment
with steam.
Q:
Are there similar machines in the marketplace?
There is no competition. I know of no other machine that does what this machine
does: provide a continuous flow of 100%humidified air
at 32%C to rest the sinuses without interruption for 10-12 hours. Other
machines available are either improved steamers with no temperature control
containing 2 oz of water lasting only 10 minutes, or sophisticated machines
costing upwards of $1200 specially designed for operating room use.
