I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to describe the main differences.
First I’ll claim that I’ve always wondered why many people in the industry often call a computerized CPAP machine something besides what it is – an automated CPAP machine. You will often hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is caused by a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will likely be in a constant pressure. Therefore, the appropriate term for 睡眠測試 which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air through your partially obstructed airway to be able to remove the obstruction and to let you breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air with 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 does not use a constant pressure. Rather, the equipment is designed to sense your breathing with the use of a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the contrary, if the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people with sleep apnea breathe normally for at least some part of the night, it makes sense that a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening 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 first time CPAP users.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the main advantage of a computerized CPAP machine might not be the reduced average pressure, however it may simply be which you don’t need to bother about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter modifications in your condition.
As with most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup from 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 as the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure may make sense. I might typically recommend utilizing the default minimum and maximum pressure settings because these settings allows for that maximum average pressure reduction and the highest degree of patient comfort.
Yet another excellent benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to deliver a continuing pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment the first time.
The two main kinds of sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction within the thalamus section of the brain, while obstructive sleep apnea occurs as a result of 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 impact 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 in order to avoid increasing the pressure during central apnea events wherein the airway has already been open. Similarly, advanced 呼吸機 could also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a summary of the benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure
No requirement to worry about adjusting a constant pressure as the condition changes
Flexibility – the equipment may be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
