Sleep Apnea is a dangerous condition
that usually gets worse as we age. A great treatment for sleep apnea is
the use of a CPAP machine and mask while sleeping. Picking the right
machine initially may save your life because it is so important to treat
the condition. Many patients give up after a week or two because of
One of the primary reasons is the
wrong mask. We discussed and compared
CPAP masks in an earlier article. We
will focus on the CPAP machines in this article. There are various
manufacturers and configurations.
Some users complain of a dry throat
when using a CPAP overnight. The primary reason for the dry throat is
lack of humidity. The filters tend to remove the humidity from the
air. This problem can be solved by adding a humidifier.
A pass-over heated humidifier is
best. On warm days you may not need the heat, but during cold nights it
is beneficial. Avoid humidifiers that use a wick type humidifier. The
pass-over humidifiers are much easier to clean.
Another feature you may want to
consider is auto-CPAP. Auto-CPAPs will regulate the pressure according
to your apnea. You may not need 14 cm of water (that is a pressure
setting) all night.
Most of the night you may only need
9 or 10 cm of pressure. So why get a rigid straight CPAP?Most CPAPs
ramp up from a smaller pressure to your limit. The ramp function may
help you fall asleep or fall back to sleep if you wake up in the middle
of the night. Pressing the ramp button will bring the pressure back
A new feature that many CPAP users
love is the C-flex. These new machines will vary the pressure in
accordance with your inhale or exhale. The pressure will be high on
your inhale but then relax after your lungs are filled. The pressure on
exhale can be set by the user.
There are a couple good machines on
the market. Goodknight is a popular manufacturer. Many vendors will
offer the 420G CPAP with heated humidifier for just under $500. It is
extremely small and is compatible with various international plug
Resmed also offers a CPAP with a
heated humidifier, but the best CPAP machine is made by Respironics.
Their REMstar Pro 2 offers all the features above including C-flex. You
can get the Pro-2 for just under $600 with the humidifier. This is a
auto-CPAP with a ramp function.
Another very important feature is
the smart card that comes with the unit. You will need to buy a card
reader and software to read the data but it is well worth it. On the
side of the unit there is a card slot that uses a credit card sized card
to record your sleep activity.
Plug the card reader into your USB
port on your computer and install the software. After about a week pull
the card (you can switch out cards because your software will come with
an extra card) and use the reader to input the data into your computer.
The program will tell you how many apnea episodes you had during the
night. The data includes and distinguishes between central and
obstructive apnea episodes.
The use of this machine with the
Resmed Activa nasal mask will likely give you a good nights sleep. If
you are new to CPAP try wearing the mask an hour before you go to bed
and go to bed tired. See our CPAP mask comparison article.
