I’m often asked the question, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to explain the key differences.
First I’ll say that I’ve always wondered the reasons people in the business have a tendency to call an automated CPAP machine something apart from what it is – an automated CPAP machine. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air is going to be at a constant pressure. Therefore, the correct term to use for 睡眠測試 which automatically adjusts pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway so that you can get rid of the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
An automatic 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. Once the machine senses you are breathing well, the delivered pressure will be lower. On the contrary, if the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Since most individuals with sleep apnea breathe normally for at least some part of the night, it makes sense that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening in comparison with a CPAP machine which delivers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the main benefit from a computerized CPAP machine will 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. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter alterations in your condition.
As with most CPAP machines, automatic CPAP machines are created 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 likely be set. Usually the 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 improving the minimum pressure could make sense. I would more often than not recommend using the default minimum and maximum pressure settings as these settings allows for your maximum average pressure reduction and also the highest level of patient comfort.
Another great benefit of automatic CPAP machines is that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you get yourself a machine which is often set to provide a continuing pressure like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment the first time.
The two main kinds of apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction inside the thalamus area of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive apnea, but CPAP machines will have no impact 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 prevent enhancing the pressure during central apnea events where the airway is definitely open. Similarly, advanced 睡眠呼吸機 may also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is really a summary of the benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure
No need to be worried about adjusting a constant pressure when your condition changes
Flexibility – the device could be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
