I am often asked the issue, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I will set out to explain the main differences.
First I’ll claim that I’ve always wondered why many people in the industry have a tendency to call an automatic CPAP machine something other than what exactly it is – an 氧氣機. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air will be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting according to your preferences is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway in order to remove the obstruction and to enable you to breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine fails to utilize a constant pressure. Rather, the device is made to sense your breathing with the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will be lower. On the other hand, once the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most people who have sleep apnea breathe normally for about some area of the night, it stands to reason that a constant pressure is normally 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 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.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the key benefit of an automated CPAP machine may not the reduced average pressure, but it may simply be that you don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will be getting 陽壓呼吸器 therapy no matter modifications in your trouble.
Similar to most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup in the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might seem sensible. I would typically recommend utilizing the default minimum and maximum pressure settings because these settings allows for the maximum average pressure reduction and also the highest level of patient comfort.
Another excellent benefit from automatic CPAP machines is that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to offer a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment for the first time.
The two main kinds of apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction inside the thalamus part of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients who are suffering from obstructive sleep apnea, but CPAP machines may have no effect on central apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid increasing the pressure during central apnea events where the airway has already been open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a summary of the benefits of using an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No requirement to be worried about adjusting a continuing pressure as the condition changes
* Flexibility – the device can be set to automatic mode or constant mode
* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
