I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I’ll lay out to explain the key differences.
First I’ll claim that I’ve always wondered why many people in the market often call a computerized CPAP machine something apart from what it is – an automated CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is a result of 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 term CPAP, however, doesn’t imply that the continuously delivered air will likely be with a constant pressure. Therefore, the correct term for 睡眠測試 which automatically adjusts the pressure setting in accordance with your needs is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway so that you can remove the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do that by blowing air at a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine will not make use of a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure is going to be lower. On the other hand, if the machine senses you’re not breathing well – that is certainly, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people who have obstructive sleep apnea breathe normally for around some area of the night, it makes sense which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening in contrast to a CPAP machine which delivers 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 main benefit of a computerized CPAP machine may not be the reduced average pressure, nevertheless it may simply be which you don’t need to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will end up getting optimal CPAP therapy irrespective of alterations in your trouble.
Similar to most CPAP machines, automatic CPAP machines are made 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 likely be set. Usually default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I might more often than not recommend making use of the default minimum and maximum pressure settings as these settings will allow for your maximum average pressure reduction and the highest amount of patient comfort.
Yet another excellent advantage of automatic CPAP machines is that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who are using CPAP equipment the first time.
There are 2 types of apnea – central and obstructive. Central sleep apnea occurs because of a dysfunction in 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 apnea, but CPAP machines could have no influence on pazbvl 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 enhancing the pressure during central apnea events in which the airway is definitely open. Similarly, advanced 睡眠窒息症 may also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is actually a breakdown of the advantages of employing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure
No reason to worry about adjusting a continuing pressure as the condition changes
Flexibility – the equipment may be set to automatic mode or constant mode
Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas.
