I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to describe the main differences. First I’ll say that I’ve always wondered why many people in the industry tend to call an automatic CPAP machine something other than what it is – 睡眠窒息症. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding of the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air will likely be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting according to your preferences is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway to be able to eliminate the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines do that by blowing air with a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine fails to use a constant pressure. Rather, the machine was created to sense your breathing by using a pressure feedback device. When 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 is going to be higher.
As most people who have apnea breathe normally for at least some area 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 course of an evening in comparison with 睡眠呼吸機 which offers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the main benefit from a computerized CPAP machine might not be the reduced average pressure, nevertheless it may just be that you don’t have to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will end up getting optimal CPAP therapy no matter modifications 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. During the initial setup from the machine the minimum and maximum pressures is going to be set. Usually default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure may make sense. I might more often than not recommend using the default minimum and maximum pressure settings as these settings allows for your maximum average pressure reduction as well as the highest level of patient comfort.
Another excellent benefit of automatic CPAP machines is the fact they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to provide a continuing pressure similar to a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who vfwfvc using CPAP equipment the very first time.
There are two varieties of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs because of a dysfunction within the thalamus part of the brain, while obstructive apnea occurs as a result of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive sleep apnea, but CPAP machines will have no influence on central obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events in which the airway is definitely open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a review of the benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No reason to concern yourself with adjusting a continuing pressure when your condition changes, Flexibility – the 睡眠窒息症 may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
