I’m often asked the question, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the market tend to call an automatic CPAP machine something besides what it is – an automatic CPAP machine. 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 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 mean that the continuously delivered air will likely be with a constant pressure. Therefore, the proper term for 睡眠測試 which automatically adjusts pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air through your partially obstructed airway to be able 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 with a constant pressure throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine does not make use of a constant pressure. Rather, the equipment was created to sense your breathing by using a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will likely be lower. On the contrary, if the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most people with sleep apnea breathe normally for around some area of the night, it makes sense which 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 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.
If 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 that you don’t have to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will be getting optimal CPAP therapy regardless of changes in your trouble.
Similar to most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup of the machine the minimum and maximum pressures is going to be set. Usually the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O as the maximum pressure is utilized. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure may make sense. I would personally typically recommend utilizing the default minimum and maximum pressure settings as these settings will permit for your maximum average pressure reduction and also the highest level of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which may be set to provide a continuing pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment the very first time.
There are two types of apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus section of the brain, while obstructive obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive apnea, but CPAP machines will have no effect on pazbvl obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent improving the pressure during central apnea events in which the airway is already open. Similarly, advanced 睡眠窒息症 may also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is a summary of the benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure
No reason to worry about adjusting a constant pressure when your condition changes
Flexibility – the machine could be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
