I’m often asked the question, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I will set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the industry tend to call an automated CPAP machine something other than 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 caused by a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air will be with a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts the pressure setting according to your preferences is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway in order to eliminate the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do this by blowing air in a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automatic CPAP machine fails to use a constant pressure. Rather, the device is designed to sense your breathing through the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will likely 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 will be higher.
Because most people with sleep apnea breathe normally for around some area of the night, it stands to reason which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night compared 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.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit from a computerized CPAP machine may not the reduced average pressure, nevertheless it may simply be which you don’t have to worry about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you may be getting 呼吸機 therapy no matter modifications in your trouble.
As with 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 is going to be set. Usually the default setting of 4 cm H2O since 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 might make sense. I would almost always recommend utilizing the default minimum and maximum pressure settings since these settings will permit for the maximum average pressure reduction and the highest amount of patient comfort.
Another excellent advantage of automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which can be set to deliver a continuing pressure just like an ordinary 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 kinds of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction inside the thalamus section 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 who suffer from obstructive obstructive sleep apnea, but CPAP machines may have no impact on central 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 where the airway is definitely open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is actually a review of some great benefits of using an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No reason to concern yourself with adjusting a constant pressure as the condition changes
* Flexibility – the equipment can be set to automatic mode or constant mode
* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
