I am often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the primary differences.

First I’ll say that I’ve always wondered the reasons people in the business tend to call an automated CPAP machine something apart from what it is – an 氧氣機. You will sometimes hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will likely be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts pressure setting according to your preferences is automatic CPAP machine.

A CPAP machine is made to blow air via your partially obstructed airway in order to eliminate the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air with a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.

A computerized CPAP machine does not use a constant pressure. Rather, the machine is designed to sense your breathing by using a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure will be lower. On the other hand, if the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.

As most people who have apnea breathe normally for around some portion of the night, it makes sense which a constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in comparison with a CPAP machine which offers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.

In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit of an automatic CPAP machine may not really the reduced average pressure, however it may simply be that you simply don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be getting 呼吸機 therapy no matter modifications in your condition.

Just like most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup of the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I might typically recommend using the default minimum and maximum pressure settings because these settings will allow for your maximum average pressure reduction as well as the highest level of patient comfort.

Yet another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to provide a constant pressure just like an ordinary CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those people who are using CPAP equipment for the first time.

There are two varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus area of the brain, while obstructive obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who suffer from obstructive sleep apnea, but CPAP machines will have no impact on central obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events in which the airway is already open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).

Below is actually a breakdown of the benefits of using an automatic CPAP machine:

** Approximately 40% overall reduction in delivered pressure

* No need to concern yourself with adjusting a continuing pressure when your condition changes

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

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