I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain 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 apart from what exactly it is – an 氧氣機. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding in the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t mean 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 according to your needs is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway in order to remove the obstruction and to let you breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air in a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine fails to make use of a constant pressure. Rather, the machine is made to sense your breathing with the use of a pressure feedback device. When the machine senses you might be breathing well, the delivered pressure is going to be lower. On the other hand, once the machine senses you’re not breathing well – that is certainly, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most individuals with obstructive sleep apnea breathe normally for around some portion of the night, it makes sense which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night compared 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 first time CPAP users.
If your prescribed pressure setting is fairly low – under 10 cm H2O – the primary benefit of an automated CPAP machine may not be the reduced average pressure, nevertheless it may just be that you simply don’t need to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will be getting 睡眠呼吸中止症 therapy regardless of changes in your problem.
As with most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup in the machine the minimum and maximum pressures is going to be set. Normally the default setting of 4 cm H2O because 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 might make sense. I would personally almost always recommend making use of the default minimum and maximum pressure settings because these settings will allow for the maximum average pressure reduction and also the highest amount of patient comfort.
Another great benefit of automatic CPAP machines is that they’re really two machines in just one. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which can be set to deliver a constant pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those 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 inside the thalamus area of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive apnea, but CPAP machines will have no effect on central apnea. Some automatic CPAP machines such as 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 has already been open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is a review of some great benefits of utilizing an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No need to concern yourself with adjusting a continuing pressure as 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
