I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the key differences.
First I’ll state that I’ve always wondered why many people in the industry tend to call an automated CPAP machine something apart from what exactly it is – an automated CPAP machine. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion 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 word CPAP, however, doesn’t mean that the continuously delivered air will likely be with a constant pressure. Therefore, the appropriate term for 睡眠窒息症 which automatically adjusts pressure setting in accordance with your needs is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway in order to eliminate the obstruction and to enable you to breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air at a constant pressure throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine fails to use a constant pressure. Rather, the equipment is made to sense your breathing with the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will be lower. On the contrary, if the machine senses you’re not breathing well – which is, when 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 portion of the night, it makes sense that the constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night compared 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 comparatively low – under 10 cm H2O – the key benefit from an automatic CPAP machine will not be the reduced average pressure, however it may just be that you simply don’t need to bother about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy no matter changes in your trouble.
As with most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup from the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure is used. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would personally typically 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 benefit from automatic CPAP machines is the fact that they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment the first time.
The two main varieties of apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction inside the thalamus section of the brain, while obstructive obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive obstructive sleep 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 in order to avoid increasing the pressure during central apnea events wherein the airway is already open. Similarly, advanced 睡眠呼吸機 could also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is really a summary of the advantages of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No need to worry about adjusting a continuing pressure as your condition changes
Flexibility – the machine could be set to automatic mode or constant mode
Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
