睡眠呼吸機 – Why So Much Attention..

I’m often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll lay out to explain the primary differences.

First I’ll state that I’ve always wondered the reasons people in the business tend to call an automated CPAP machine something besides what exactly it is – an automatic CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding from the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure is going to 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 for 睡眠測試 which automatically adjusts the stress setting according to your needs is automatic CPAP machine.

A CPAP machine was created to blow air through your partially obstructed airway so that you can get rid of the obstruction and to allow you to breathe normally. What many individuals call “regular” CPAP machines do this by blowing air at a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.

An automatic CPAP machine does not utilize a constant pressure. Rather, the machine is designed 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 likely be lower. On the other hand, when the machine senses you’re not breathing well – which is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.

Because most people who have sleep apnea breathe normally for about some area 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 new CPAP users.

In case your prescribed pressure setting is fairly low – under 10 cm H2O – the key benefit from a computerized CPAP machine might not be the reduced average pressure, nevertheless it may just be that you simply don’t need to worry about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of changes 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. During the initial setup in the machine the minimum and maximum pressures is going to be set. Usually 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 enhancing the minimum pressure might make sense. I would personally typically recommend utilizing the default minimum and maximum pressure settings as these settings will permit for the maximum average pressure reduction as well as the highest degree of patient comfort.

Another excellent benefit of automatic CPAP machines is the fact that they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which can be set to deliver a constant pressure similar to a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to individuals who are using CPAP equipment the first time.

The two main kinds of apnea – central and obstructive. Central 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 created to open the airway for patients who are suffering from obstructive obstructive sleep apnea, but CPAP machines could have no effect on pazbvl obstructive sleep apnea. Some automatic CPAP machines like 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 睡眠窒息症 can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).

Below is actually a breakdown of the benefits of using an automatic CPAP machine:

Approximately 40% overall decline in delivered pressure

No requirement to concern yourself with adjusting a continuing pressure as the condition changes

Flexibility – the equipment can be set to automatic mode or constant mode

Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas.
