I’m often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to clarify the primary differences.

First I’ll claim that I’ve always wondered why many people in the market tend to call an automated CPAP machine something other than what it is – an automated CPAP machine. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air will likely be in a constant pressure. Therefore, the appropriate term to use for 睡眠窒息症 which automatically adjusts the pressure setting according to your needs is automatic CPAP machine.

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

A computerized CPAP machine does not make use of a constant pressure. Rather, the machine is designed to sense your breathing with the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will be lower. On the other hand, once the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.

Since most people with apnea breathe normally for around some portion of the night, it makes sense that 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 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 comparatively low – under 10 cm H2O – the key benefit of an automated CPAP machine might not be the reduced average pressure, however it may just be which you don’t have to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will end up getting optimal CPAP therapy no matter changes in your problem.

Just like most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure may make sense. I might more often than not recommend using the default minimum and maximum pressure settings since these settings will allow for the maximum average pressure reduction and the highest degree of patient comfort.

Another excellent benefit from automatic CPAP machines is that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which can be set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those who are using CPAP equipment the very first time.

The two main varieties of sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction in the thalamus section of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive apnea, but CPAP machines could have no influence on pazbvl sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events wherein the airway has already been open. Similarly, advanced 睡眠呼吸機 could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).

Below is actually a review of the benefits of employing an automatic CPAP machine:

Approximately 40% overall decline in delivered pressure

No need to be worried about adjusting a continuing pressure as the condition changes

Flexibility – the machine may be set to automatic mode or constant mode

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