I am often asked the issue, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I will set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the business often call an automated CPAP machine something other than what it is – an 氧氣機. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts pressure setting based on your needs is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway in order to get rid of the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
An automatic CPAP machine does not use a constant pressure. Rather, the machine is made to sense your breathing through the use of a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will be lower. On the other hand, once the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people with sleep apnea breathe normally for around 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 path of a night in comparison with a CPAP machine which offers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.
Should your prescribed pressure setting is comparatively low – under 10 cm H2O – the key benefit from an automated CPAP machine may not really the reduced average pressure, but it may just be which you don’t have to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you will end up getting 睡眠呼吸中止症 therapy no matter changes in your condition.
Just like most CPAP machines, automatic CPAP machines are made 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 be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O as the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might seem sensible. I might more often than not recommend utilizing the default minimum and maximum pressure settings as these settings will allow for the maximum average pressure reduction and also the highest amount of patient comfort.
Another great benefit from automatic CPAP machines is the fact they’re really two machines in just one. You get a CPAP machine which adjusts pressure automatically, and you also obtain a machine which can be set to provide a constant pressure just like a normal CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment for the first time.
The two main varieties of sleep apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction within the thalamus area of the brain, while obstructive obstructive sleep 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 will have no effect on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events wherein the airway is definitely open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is really a summary of some great benefits of using an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No requirement to be worried about adjusting a constant pressure as the condition changes
* Flexibility – the device can be set to automatic mode or constant mode
* Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
