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 set out to explain the primary differences.
First I’ll claim that I’ve always wondered the reasons people in the industry tend to call an automated CPAP machine something besides what exactly it is – a computerized CPAP machine. You will often hear people call these types of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will likely be in a constant pressure. Therefore, the proper term to use for 睡眠窒息症 which automatically adjusts the stress setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is designed to blow air via 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 accomplish this by blowing air at a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine will not make use of a constant pressure. Rather, the equipment is made to sense your breathing with the use of a pressure feedback device. When the machine senses you happen to 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.
Since most individuals with apnea breathe normally for around some part of the night, it stands to reason that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in comparison 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 brand new CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit from an automated CPAP machine will not be the reduced average pressure, however it may simply be which you don’t need to bother about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of changes in your condition.
As with most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup in 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 can be used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might make sense. I would personally almost always recommend making use of the default minimum and maximum pressure settings as these settings allows for the maximum average pressure reduction and also the highest level of patient comfort.
Another excellent benefit of automatic CPAP machines is that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to provide a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to individuals who are using CPAP equipment the first time.
There are 2 kinds of apnea – central and obstructive. Central apnea occurs due to a dysfunction within the thalamus part of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines could have no impact on pazbvl apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent enhancing the pressure during central apnea events in which the airway has already been open. Similarly, advanced 睡眠呼吸機 could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a breakdown of some great benefits of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No need to be worried about adjusting a constant pressure as your condition changes
Flexibility – the equipment may be set to automatic mode or constant mode
Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
