I am often asked the issue, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post 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 an automatic CPAP machine something other than what it is – an 製氧機. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the entire sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts the pressure setting in accordance with your preferences 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 enable you to breathe normally. What lots of people call “regular” CPAP machines do this by blowing air with a constant pressure throughout the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine will not utilize a constant pressure. Rather, the equipment 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 is going to 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 will likely be higher.
Because most people with obstructive sleep apnea breathe normally for at least some area of the night, it makes sense which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in contrast to a CPAP machine which delivers a constant pressure. This reduced pressure helps 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 primary benefit of a computerized CPAP machine may not the reduced average pressure, but it may just be which you don’t need to bother about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you will be getting 睡眠呼吸中止症 therapy irrespective of alterations 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. During the initial setup of the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O as the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might seem sensible. I would personally almost always recommend utilizing the default minimum and maximum pressure settings because these settings will permit for your maximum average pressure reduction and also the highest amount of patient comfort.
Another great benefit from automatic CPAP machines is the fact that they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to deliver a constant 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 for the first time.
There are two kinds of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction within the thalamus section of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients that suffer from obstructive sleep apnea, but CPAP machines could have no impact on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving 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 defined as shallow breathing).
Below is a review of the advantages of utilizing an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No requirement to worry about adjusting a continuing pressure as your 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
