睡眠呼吸中止症 – Unique Details On This Issue..

I am often asked the issue, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to explain the main differences.

First I’ll say that I’ve always wondered why many people in the business often call an automated CPAP machine something other than what it is – an 氧氣機. You will often hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding in the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be in a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting based on your needs is automatic CPAP machine.

A CPAP machine was created to blow air through your partially obstructed airway in order to get rid of the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do that by blowing air with a constant pressure through the entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise not.

A computerized CPAP machine will not utilize a constant pressure. Rather, the machine is made to sense your breathing through the use of a pressure feedback device. When the machine senses you are breathing well, the delivered pressure will likely be lower. On the other hand, if the machine senses you’re not breathing well – that is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.

As most people who have apnea breathe normally for around some portion of the night, it makes sense that a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night compared with a CPAP machine which delivers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.

If your prescribed pressure setting is relatively low – under 10 cm H2O – the key benefit from an automatic CPAP machine may not be the reduced average pressure, nevertheless it may simply be that you simply don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will end up getting 呼吸機 therapy irrespective of changes in your problem.

Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures is going to be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O because the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might make sense. I might almost always recommend making use of the default minimum and maximum pressure settings as these settings allows for your maximum average pressure reduction and also the highest amount of patient comfort.

Yet another excellent benefit of automatic CPAP machines is the fact they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, and you obtain a machine which can be set to offer a continuing pressure just like a normal CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment for the first time.

There are 2 varieties of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs because of a dysfunction in the thalamus area of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive apnea, but CPAP machines could have no impact on central obstructive sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid increasing the pressure during central apnea events wherein the airway has already been open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is defined as shallow breathing).

Below is really a review of the advantages of employing an automatic CPAP machine:

** Approximately 40% overall decrease in delivered pressure

* No need to worry about adjusting a continuing pressure when your condition changes

* Flexibility – the device can be set to automatic mode or constant mode

* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
