I am often asked the issue, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the key differences.
First I’ll claim that I’ve always wondered why many people in the industry tend to call a computerized CPAP machine something other than what it is – an 氧氣機. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding of the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air is going to be with a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts the stress setting in accordance with 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 lots of people call “regular” CPAP machines do that by blowing air at a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine fails to utilize a constant pressure. Rather, the device 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 be lower. On the other hand, once the machine senses you’re not breathing well – that is, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most people with sleep apnea breathe normally for around some portion of the night, it makes sense that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in comparison with a CPAP machine which offers 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 advantage of an automated CPAP machine may not really the reduced average pressure, however it may simply be that you simply don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be getting 呼吸機 therapy regardless of alterations in your trouble.
Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup in 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 since the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might seem sensible. I would personally more often than not recommend utilizing the default minimum and maximum pressure settings because these settings allows for your maximum average pressure reduction and the highest level of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which can be set to offer a constant 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 the very first time.
There are two varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus part of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive apnea, but CPAP machines will have no impact on central obstructive sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent enhancing the pressure during central apnea events wherein 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 actually a breakdown of the benefits of employing 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
