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 set out to describe the main differences.
First I’ll claim that I’ve always wondered why many people in the industry have a tendency to call an automated CPAP machine something besides what exactly it is – a computerized CPAP machine. 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 of the acronym CPAP. CPAP stands 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 correct term for 睡眠窒息症 which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway so that you can get rid of the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine fails to utilize a constant pressure. Rather, the machine is designed to sense your breathing by using a pressure feedback device. If the machine senses you are breathing well, the delivered pressure will likely 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.
Since most individuals with apnea breathe normally for about some area 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 course of a night in comparison with a CPAP machine which delivers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the key advantage of an automated 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 down the road. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter changes in your trouble.
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 will be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I might more often than not recommend using the default minimum and maximum pressure settings as these settings will allow for that maximum average pressure reduction as well as the highest degree of patient comfort.
Another great advantage of automatic CPAP machines is that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which may be set to offer a continuing pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who are using CPAP equipment the very first time.
There are 2 types of apnea – central and obstructive. Central apnea occurs as a result of a dysfunction in 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 who are suffering from obstructive apnea, but CPAP machines could have no influence on pazbvl obstructive sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events where the airway has already been open. Similarly, advanced 睡眠窒息症 could also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is really a review of some great benefits of using an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No need to concern yourself with adjusting a continuing pressure when your condition changes
Flexibility – the device can be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
