I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll lay out to clarify the key differences.
First I’ll say that I’ve always wondered the reasons people in the market tend to call an automated CPAP machine something other than what exactly it is – an automated CPAP machine. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air is going to be at a constant pressure. Therefore, the appropriate term for 睡眠測試 which automatically adjusts the stress setting according to your preferences is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway to be able to eliminate the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do this by blowing air in a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automatic CPAP machine does not make use of a constant pressure. Rather, the machine is made to sense your breathing with the use of a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will be lower. On the contrary, once the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Since most people with obstructive sleep apnea breathe normally for about some portion of the night, it stands to reason that the 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 offers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit from an automated CPAP machine might not be the reduced average pressure, nevertheless it may just be which you don’t need to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of modifications in your problem.
Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup in the machine the minimum and maximum pressures is going to be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would personally almost always recommend using the default minimum and maximum pressure settings because these settings allows for the maximum average pressure reduction and the highest amount of patient comfort.
Another excellent advantage of automatic CPAP machines is the fact they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who are using CPAP equipment for the first time.
There are 2 kinds of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus area of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines could have no impact on pazbvl apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events where the airway is definitely open. Similarly, advanced 呼吸機 could also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is actually a review of the advantages of using an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure
No need to concern yourself with adjusting a constant pressure as the condition changes
Flexibility – the machine can be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
