I am often asked the issue, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I will set out to explain the main differences.
First I’ll state that I’ve always wondered why many people in the business have a tendency to call an automatic CPAP machine something apart from what exactly it is – an 製氧機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion this is because of a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air is going to be with a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the stress setting based on your needs is automatic CPAP machine.
A CPAP machine is designed to blow air through your partially obstructed airway in order to get rid of the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do this by blowing air with a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine will not use a constant pressure. Rather, the device was created to sense your breathing with the use of a pressure feedback device. When 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 – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people with obstructive sleep apnea breathe normally for around some part of the night, it stands to reason which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night compared with a CPAP machine which offers 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 primary benefit of an automatic CPAP machine may not the reduced average pressure, but it may just be which you don’t have to worry about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will be getting 睡眠呼吸中止症 therapy regardless of modifications in your condition.
Similar to most CPAP machines, automatic CPAP machines are designed 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. Usually default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might sound right. I would personally almost always recommend utilizing the default minimum and maximum pressure settings since these settings will permit for your maximum average pressure reduction and the highest level of patient comfort.
Another great benefit of automatic CPAP machines is the fact they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which can be set to offer a continuing 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 first time.
There are two varieties of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction inside the thalamus section 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 obstructive sleep apnea, but CPAP machines will have no influence on central obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid 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 defined as shallow breathing).
Below is a review of the benefits of employing an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No need to be worried about adjusting a constant pressure when 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
