I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to clarify the key differences.
First I’ll say that I’ve always wondered the reasons people in the business have a tendency to call an automatic CPAP machine something besides what it is – a computerized CPAP machine. You will sometimes hear people call these sorts 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 be delivered continuously through the sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air will likely be with a constant pressure. Therefore, the proper term to use for 睡眠測試 which automatically adjusts pressure setting in accordance with your preferences 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 enable you to breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
An automated CPAP machine will not use 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 happen to be breathing well, the delivered pressure will likely be lower. On the other hand, if the machine senses you’re not breathing well – which is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most individuals with apnea breathe normally for around some part 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 path of a night in contrast to a CPAP machine which delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
If your prescribed pressure setting is relatively low – under 10 cm H2O – the main advantage of a computerized CPAP machine might not be the reduced average pressure, nevertheless it may simply be that you simply 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 regardless of changes in your trouble.
Just like most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup from the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure is used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would more often than not recommend using the default minimum and maximum pressure settings because these settings will permit for that maximum average pressure reduction and also the highest amount of patient comfort.
Yet another excellent benefit from automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you obtain a machine which may be set to provide a continuing pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who are using CPAP equipment the first time.
There are 2 types of apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive apnea, but CPAP machines could have no effect on pazbvl obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid improving the pressure during central apnea events wherein the airway is definitely open. Similarly, advanced 睡眠窒息症 could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is a breakdown of the advantages of utilizing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure
No requirement to concern yourself with adjusting a constant pressure when your condition changes
Flexibility – the machine could be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
