I am often asked the issue, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to explain the key differences.
First I’ll claim that I’ve always wondered the reasons people in the industry often call an automated CPAP machine something other than what it is – an 氧氣機. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is caused by a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air is going to be at a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway in order to eliminate the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air with a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or not.
An automated CPAP machine fails to use a constant pressure. Rather, the device was created 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 likely be lower. On the other hand, once 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 who have sleep apnea breathe normally for around some portion of the night, it makes sense which 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 contrast to 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 new CPAP users.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the primary advantage of an automatic CPAP machine may not really the reduced average pressure, however 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 will be getting 呼吸機 therapy irrespective of modifications in your problem.
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 in the machine the minimum and maximum pressures is going to be set. Normally the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is used. However, if 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 since these settings will allow for the maximum average pressure reduction as well as the highest degree of patient comfort.
Another great advantage of automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to provide a continuing pressure just like an ordinary CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment the first time.
There are 2 kinds of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus area of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive 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 prevent enhancing the pressure during central apnea events where the airway has already been open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a review of the benefits of employing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No need 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 difference between obstructive apneas/hypopneas and central apneas/hypopneas
