I’m often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to clarify the key differences.
First I’ll claim that I’ve always wondered the reasons people in the industry tend to call a computerized CPAP machine something apart from what it is – an automated CPAP machine. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is because 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 through the entire sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air will be at a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts the pressure setting in accordance with your needs 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 many individuals call “regular” CPAP machines do this by blowing air at a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or not.
An automated CPAP machine fails to make use of a constant pressure. Rather, the machine was created to sense your breathing through the use of a pressure feedback device. When 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 – which is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most individuals with obstructive sleep apnea breathe normally for about some part of the night, it makes sense which a constant pressure is usually 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 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 fairly low – under 10 cm H2O – the main benefit of an automated CPAP machine may not be the reduced average pressure, however it may simply be which you don’t need to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will end up getting optimal CPAP therapy regardless of alterations in your trouble.
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 will be set. Usually default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure could make sense. I would more often than not recommend using the default minimum and maximum pressure settings as these settings will allow for that maximum average pressure reduction and the highest amount of patient comfort.
Another great benefit of automatic CPAP machines is the fact they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, and you get yourself a machine which may be set to offer a jfsqgg pressure similar to a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those who are using CPAP equipment the first time.
The two main varieties of apnea – central and obstructive. Central apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive sleep apnea, but CPAP machines may have no impact on central obstructive 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 increasing the pressure during central apnea events wherein the airway is already open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is really a breakdown of the benefits of employing an automatic CPAP machine: Approximately 40% overall decrease in delivered pressure. No requirement to be worried about adjusting a constant pressure when your condition changes. Flexibility – the machine can be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
