I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I will set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the business tend to call a computerized CPAP machine something other than what exactly it is – an 氧氣機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is because of a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the appropriate 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 made to blow air through your partially obstructed airway in order to remove the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air in a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
An automated CPAP machine will not make use of a constant pressure. Rather, the machine is designed to sense your breathing with the use of a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the other hand, when the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most individuals with apnea breathe normally for around some part of the night, it stands to reason that the 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 helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the main advantage of a computerized CPAP machine may not really the reduced average pressure, nevertheless it may simply be that you simply don’t need to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you will end up getting 睡眠呼吸中止症 therapy irrespective of changes in your condition.
Just like most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures will likely be set. Usually the default setting of 4 cm H2O because 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 more often than not recommend making use of the default minimum and maximum pressure settings as these settings will allow for your maximum average pressure reduction and the highest amount of patient comfort.
Another great advantage of automatic CPAP machines is that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and 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 attractive to many CPAP users, especially to those people who are using CPAP equipment for the first time.
The two main varieties of sleep apnea – central and obstructive. Central apnea occurs as a result of a dysfunction within the thalamus area of the brain, while obstructive sleep apnea occurs due to 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 obstructive 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 increasing the pressure during central apnea events where the airway is already open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is actually a review of some great benefits of utilizing an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No requirement to be worried about adjusting a continuing pressure as your 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
