I am often asked the issue, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the market tend to call an automatic CPAP machine something apart from what it is – an 氧氣機. You will often hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is because of a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air is going to be in a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting in accordance with your needs is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway in order to 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 throughout the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine does not use a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure is going to be lower. On the other hand, when the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Since most individuals with apnea breathe normally for about some part of the night, it stands to reason that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening 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.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the key advantage of an automatic CPAP machine may not be the reduced average pressure, nevertheless it may just be that you simply don’t have to worry about adjusting your pressure setting in the future. An automatic CPAP machine virtually guarantees you may be getting 睡眠呼吸中止症 therapy irrespective of alterations in your trouble.
Similar to most CPAP machines, automatic CPAP machines are designed 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. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might sound right. I might typically recommend utilizing the default minimum and maximum pressure settings as these settings will permit for your maximum average pressure reduction as well as the highest amount of patient comfort.
Another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to deliver a constant pressure just like a normal CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to individuals who are using CPAP equipment the first time.
There are two kinds of obstructive sleep apnea – central and obstructive. Central apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive sleep apnea, but CPAP machines could have no influence on central sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events wherein the airway has already been open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is really a review of the benefits of using an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No need to be worried about adjusting a constant pressure when your condition changes
* Flexibility – the machine can be set to automatic mode or constant mode
* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
