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 lay out to describe the primary differences.
First I’ll say that I’ve always wondered why many people in the market have a tendency to call a computerized CPAP machine something apart from what it is – an automatic CPAP machine. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding of the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air is going to be in a constant pressure. Therefore, the appropriate term to use for 睡眠窒息症 which automatically adjusts the pressure setting based on your needs is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway to be able to remove the obstruction and to allow you to breathe normally. What many individuals call “regular” CPAP machines do this by blowing air in a constant pressure throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine does not 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 happen to be breathing well, the delivered pressure will be lower. On the other hand, when the machine senses you’re not breathing well – that is, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most people who have apnea breathe normally for about some part of the night, it stands to reason 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 contrast to a CPAP machine which delivers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the key benefit of an automatic CPAP machine may not be the reduced average pressure, however it may just be that you don’t need to bother about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you will be getting optimal CPAP therapy no matter changes in your condition.
Similar to most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup from the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure may make sense. I would personally typically recommend making use of the default minimum and maximum pressure settings as these settings allows for your maximum average pressure reduction and the highest amount of patient comfort.
Another excellent benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You get a CPAP machine which adjusts pressure automatically, and you get yourself a machine which can 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 individuals who are using CPAP equipment the first time.
The two main kinds of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction in the thalamus section of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive obstructive sleep apnea, but CPAP machines will have no effect on pazbvl sleep apnea. Some automatic CPAP machines like 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 has already been open. Similarly, advanced 睡眠窒息症 may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a breakdown of the advantages of using an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure
No need to be worried about adjusting a constant pressure as 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.
