I’m often asked the issue, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I will set out to explain the primary differences.
First I’ll claim that I’ve always wondered the reasons people in the market tend to call an automatic CPAP machine something other than what exactly it is – an 氧氣機. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding in the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be at a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting in accordance with your needs is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway in order to remove the obstruction and to enable you to breathe normally. What many individuals call “regular” CPAP machines do that by blowing air at a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine does not make use of a constant pressure. Rather, the equipment is made to sense your breathing by using a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure is going to be lower. On the other hand, if the machine senses you’re not breathing well – that is, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Since most people who have apnea breathe normally for around some area of the night, it stands to reason that a constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening compared 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 first time CPAP users.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit of an automated CPAP machine may not the reduced average pressure, nevertheless it may simply be that you simply don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will end up getting 陽壓呼吸器 therapy irrespective of alterations 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. During the initial setup in 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 since the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might make sense. I would more often than not recommend using the default minimum and maximum pressure settings as these settings will permit for your maximum average pressure reduction and also the highest degree of patient comfort.
Another great benefit of automatic CPAP machines is the fact they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you get yourself a machine which can be set to deliver a constant pressure just like an ordinary 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 types of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs because of a dysfunction within the thalamus part of the brain, while obstructive obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive obstructive sleep apnea, but CPAP machines may have no effect on central obstructive sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events in which the airway has already been open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a breakdown of the advantages of using an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No requirement to concern yourself with adjusting a constant pressure as your condition changes
* Flexibility – the equipment can be set to automatic mode or constant mode
* Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
