I am often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll lay out to describe the primary differences.
First I’ll state that I’ve always wondered the reasons people in the industry often call a computerized CPAP machine something besides what exactly it is – an automated CPAP machine. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding from the 睡眠呼吸機. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air will likely be with a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts pressure setting in accordance with your needs is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway in order to get rid of the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do that by blowing air in a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine does not utilize a constant pressure. Rather, the device is designed to sense your breathing by using a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the other hand, when the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most individuals with apnea breathe normally for around some portion of the night, it makes sense that a constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in contrast to 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 brand new CPAP users.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the key benefit from a computerized CPAP machine will not be the reduced average pressure, however it may simply be which you don’t have to worry about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you will end up getting optimal CPAP therapy no matter alterations in your condition.
As with most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup in the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure could make sense. I would more often than not recommend utilizing the default minimum and maximum pressure settings because these settings will permit for your maximum average pressure reduction as well as the highest degree 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 get yourself a machine which may be set to provide a jfsqgg pressure like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those people who are using CPAP equipment for the first time.
There are 2 kinds of apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction inside the thalamus area of the brain, while obstructive apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive obstructive sleep apnea, but CPAP machines may have no impact on central 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 improving the pressure during central apnea events where the airway is definitely open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a summary of the benefits of utilizing an automatic CPAP machine: Approximately 40% overall decrease in delivered pressure. No requirement to worry about adjusting a constant pressure when your condition changes. Flexibility – the device could be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
