I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll lay out to describe the key differences.
First I’ll say that I’ve always wondered the reasons people in the business often call an automatic CPAP machine something besides what it is – a computerized CPAP machine. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air will be with a constant pressure. Therefore, the correct term to use for 睡眠窒息症 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 to be able to remove the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do this by blowing air in a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine fails to make use of a constant pressure. Rather, the equipment is made to sense your breathing with the use of a pressure feedback device. If the machine senses you are breathing well, the delivered pressure will be lower. On the contrary, once the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most individuals with apnea breathe normally for at least some part of the night, it stands to reason that a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night 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 new CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the key benefit from an automated CPAP machine may not be the reduced average pressure, however it may simply be that you don’t need to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy no matter changes in your problem.
Similar to most CPAP machines, automatic CPAP machines are designed 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 be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I might almost always recommend utilizing the default minimum and maximum pressure settings because these settings will permit for your maximum average pressure reduction and the highest degree of patient comfort.
Another excellent 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 also get a machine which can be set to deliver a constant 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 varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction in the thalamus area 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 who are suffering from obstructive apnea, but CPAP machines will have no effect on pazbvl sleep apnea. Some automatic CPAP machines like 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 in which the airway has already been open. Similarly, advanced 睡眠窒息症 could also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a review of the advantages of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No reason to be worried about adjusting a continuing pressure as the condition changes
Flexibility – the machine may be set to automatic mode or constant mode
Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas.
