I’m often asked the question, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I will set out to explain the primary differences.
First I’ll state that I’ve always wondered the reasons people in the industry have a tendency to call a computerized CPAP machine something besides what it is – an 製氧機. You will often hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air is going to be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway in order to remove the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine will not use a constant pressure. Rather, the machine is made to sense your breathing through the use of a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure will be lower. On the other hand, when the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Since most people who have obstructive sleep apnea breathe normally for at least 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 contrast to a CPAP machine which delivers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the key benefit from an automated CPAP machine may not be the reduced average pressure, nevertheless it may just be that you simply don’t need to bother about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you may be getting 陽壓呼吸器 therapy irrespective of alterations in your condition.
As with most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup from the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure can be used. However, in case your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might seem sensible. I would personally typically recommend making use of the default minimum and maximum pressure settings since these settings allows for that maximum average pressure reduction and also the highest amount of patient comfort.
Another excellent benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to provide a continuing pressure just like an ordinary 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 2 types of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus part of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive apnea, but CPAP machines will have no impact on central sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events wherein the airway is definitely open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is really a breakdown of the advantages of utilizing an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No need to worry about adjusting a constant pressure when your condition changes
* Flexibility – the machine can be set to automatic mode or constant mode
* Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
