I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to explain the key differences.
First I’ll say that I’ve always wondered the reasons people in the market tend to call a computerized CPAP machine something apart from what exactly it is – an automatic CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will likely be in a constant pressure. Therefore, the correct term for 睡眠測試 which automatically adjusts pressure setting based on your needs is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway so that you can eliminate the obstruction and to allow you to breathe normally. What many individuals call “regular” CPAP machines do this by blowing air with a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine does not utilize a constant pressure. Rather, the equipment was created to sense your breathing through the use of a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will be lower. On the other hand, when the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most individuals with obstructive sleep apnea breathe normally for about some portion of the night, it makes sense which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in contrast to 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.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the main advantage of a computerized CPAP machine might not be the reduced average pressure, however it may just be that you simply don’t need to bother about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be 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. Through the initial setup of the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would typically recommend making use of the default minimum and maximum pressure settings since these settings will permit for your maximum average pressure reduction as well as the highest degree of patient comfort.
Another excellent advantage of automatic CPAP machines is that they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to provide a constant pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment the very first time.
There are 2 kinds of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction within the thalamus area of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive sleep apnea, but CPAP machines may have no influence on pazbvl obstructive sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent enhancing the pressure during central apnea events in which the airway has already been open. Similarly, advanced 睡眠呼吸機 can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a review of the benefits of using an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure
No reason to worry about adjusting a constant pressure as your condition changes
Flexibility – the equipment may be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
