I’m often asked the issue, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the key differences.
First I’ll state that I’ve always wondered the reasons people in the market often call an automatic CPAP machine something other than what it is – an 氧氣機. You will sometimes hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion this is caused by a misunderstanding of the acronym CPAP. CPAP stands 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 likely be with a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts the pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is made to blow air using your partially obstructed airway in order to eliminate the obstruction and to allow you to breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air at a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine will not utilize a constant pressure. Rather, the machine is designed 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, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Since most individuals with obstructive sleep apnea breathe normally for around some part of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in contrast to a CPAP machine which offers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
Should your prescribed pressure setting is comparatively low – under 10 cm H2O – the primary advantage of an automatic CPAP machine may not the reduced average pressure, however it may simply be that you simply don’t need to bother about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will be getting 呼吸機 therapy regardless of changes in your condition.
Similar to most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup of 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 as the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might make sense. I might typically recommend making use of the default minimum and maximum pressure settings because these settings will allow for that maximum average pressure reduction and the highest degree of patient comfort.
Yet another excellent benefit 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 offer a continuing pressure just like an ordinary CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to individuals who are using CPAP equipment for the first time.
The two main types of apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive apnea, but CPAP machines may have no influence on central 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 wherein the airway has already been open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is a review of the advantages of using an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No reason to concern yourself with adjusting a constant pressure as the 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
