I am often asked the issue, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to explain the main differences.
First I’ll say that I’ve always wondered the reasons people in the industry tend to call an automatic CPAP machine something apart from what exactly 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 a result of a misunderstanding in the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air will likely be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting according to your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway in order to remove the obstruction and to let you breathe normally. What many individuals call “regular” CPAP machines do this by blowing air with a constant pressure throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine fails to make use of a constant pressure. Rather, the device is designed to sense your breathing by using a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure is going to be lower. On the other hand, if the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most individuals with obstructive sleep apnea breathe normally for around some area 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 compared with a CPAP machine which delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
If your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit from an automated CPAP machine may not be the reduced average pressure, however it may simply be which you don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will end up getting 呼吸機 therapy irrespective of alterations in your condition.
Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures is going to be set. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might seem sensible. I might almost always recommend utilizing the default minimum and maximum pressure settings as these settings allows for that maximum average pressure reduction and also the highest level 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, and you get a machine which can be set to provide a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment the first time.
There are two varieties of obstructive sleep apnea – central and obstructive. Central apnea occurs due to 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 that suffer from obstructive obstructive sleep apnea, but CPAP machines could have no influence on central sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing 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 defined as shallow breathing).
Below is really a review of some great benefits of employing an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No requirement to concern yourself with adjusting a continuing pressure as the condition changes
* Flexibility – the device can be set to automatic mode or constant mode
* Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
