I’m often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the main differences.
First I’ll say that I’ve always wondered the reasons people in the business often call an automated CPAP machine something apart from what exactly 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 from the 睡眠呼吸機. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be at a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway so that you can get rid of the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do that by blowing air with a constant pressure throughout the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine fails to use a constant pressure. Rather, the machine was created to sense your breathing with the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will be lower. On the other hand, once the machine senses you’re not breathing well – that is certainly, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most people with obstructive sleep apnea breathe normally for about some part 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 path of a night compared with 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.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit from an automated CPAP machine might not be the reduced average pressure, but it may simply be that you don’t need to bother about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of modifications in your problem.
As with most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup in the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would typically recommend making use of the default minimum and maximum pressure settings since these settings allows for the maximum average pressure reduction and the highest amount of patient comfort.
Another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which is often set to provide a jfsqgg pressure just like a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to individuals who are using CPAP equipment the very first time.
The two main varieties of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction within the thalamus section of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive apnea, but CPAP machines could have no effect on central sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events wherein the airway has already been open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is a review of some great benefits of using an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No requirement to be worried about adjusting a constant pressure as the condition changes. Flexibility – the device may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
