I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the key differences.
First I’ll say that I’ve always wondered why many people in the market often call an automated CPAP machine something apart from what it is – an 氧氣機. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is a result 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 sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be in a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is designed to blow air via 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 entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine will not utilize a constant pressure. Rather, the device was created to sense your breathing by using a pressure feedback device. If the machine senses you are breathing well, the delivered pressure will be lower. On the other hand, if the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most individuals with apnea breathe normally for at least some part of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in contrast to a CPAP machine which offers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the primary benefit from an automated CPAP machine may not really the reduced average pressure, however it may simply be which you don’t have to worry about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you will be getting 陽壓呼吸器 therapy irrespective of alterations in your condition.
Similar to most CPAP machines, automatic CPAP machines are made 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 likely 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 enhancing the minimum pressure might make sense. I might typically recommend utilizing the default minimum and maximum pressure settings because these settings allows for that maximum average pressure reduction and the highest level of patient comfort.
Yet another excellent benefit from automatic CPAP machines is that they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, and you also obtain a machine which can be set to offer a continuing pressure just like a regular 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 two types of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction inside the thalamus section of the brain, while obstructive apnea occurs as a result of an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive sleep apnea, but CPAP machines may have no effect on central obstructive 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 wherein the airway is already open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is actually a review of some great benefits of using an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No reason to be worried about adjusting a constant pressure as your condition changes
* Flexibility – the machine can be set to automatic mode or constant mode
* Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
