I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to clarify the key differences. First I’ll claim that I’ve always wondered the reasons people in the industry tend to call an automatic CPAP machine something apart from what it is – 睡眠呼吸機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding of 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 be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting based on your requirements is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway so that you can remove the obstruction and to let you breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine will not utilize a constant pressure. Rather, the equipment was created 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 is going to be lower. On the other hand, once the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people with obstructive sleep apnea breathe normally for around some area of the night, it stands to reason 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 in comparison with 睡眠呼吸機 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 relatively low – under 10 cm H2O – the primary advantage of a computerized CPAP machine will not be the reduced average pressure, however it may just be which you don’t need to bother about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you may be getting optimal CPAP therapy regardless of alterations in your trouble.
As with 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 likely be set. Usually the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because 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 would personally more often than not recommend using the default minimum and maximum pressure settings since these settings will permit for the maximum average pressure reduction and also the highest degree of patient comfort.
Another great advantage of automatic CPAP machines is that they’re really two machines in a single. You have a CPAP machine which adjusts pressure automatically, and you get yourself a machine which is often set to offer a continuing pressure like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to the people who vfwfvc using CPAP equipment the first time.
There are 2 varieties of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus area of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients that suffer from obstructive apnea, but CPAP machines could have no impact on central sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid increasing the pressure during central apnea events wherein the airway has already been open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is a breakdown of the advantages of employing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure, No need to be worried about adjusting a constant pressure as your condition changes, Flexibility – the 睡眠呼吸機 can be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
