I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to describe the key differences.
First I’ll state that I’ve always wondered why many people in the industry often call an automatic CPAP machine something apart from what exactly it is – a computerized CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is because of a misunderstanding from the 睡眠窒息症. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be at a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway to be able to eliminate the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine will not use a constant pressure. Rather, the machine is designed to sense your breathing with the use of a pressure feedback device. When the machine senses you happen to 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, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most individuals with apnea breathe normally for at least some part of the night, it stands to reason which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening in comparison with 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 brand new CPAP users.
If your prescribed pressure setting is relatively low – under 10 cm H2O – the key advantage of 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 in the future. An automatic CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of alterations in your problem.
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 in the machine the minimum and maximum pressures will likely be set. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O because the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would personally almost always recommend making use of the default minimum and maximum pressure settings as these settings will allow for your maximum average pressure reduction and the highest amount of patient comfort.
Yet another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in a single. You have a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which can be set to deliver a jfsqgg pressure similar to a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those who are using CPAP equipment the first time.
There are 2 varieties of apnea – central and obstructive. Central apnea occurs as a result of a dysfunction in 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 may have no influence on central sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid improving the pressure during central apnea events wherein the airway is already open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is a review of some great benefits of using an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No need to concern yourself with 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 real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
