I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to explain the primary differences.
First I’ll state that I’ve always wondered the reasons people in the industry often call an automatic CPAP machine something besides what it is – an 氧氣機. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is because of a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air is going to be with a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway in order to remove the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do this by blowing air in a constant pressure throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine does not make use of a constant pressure. Rather, the equipment is made to sense your breathing with the use of a pressure feedback device. When the machine senses you might be breathing well, the delivered pressure is going to 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 is going to be higher.
As most people with sleep apnea breathe normally for about some portion of the night, it makes sense that the constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in contrast to a CPAP machine which offers 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 key advantage of a computerized CPAP machine may not really the reduced average pressure, but it may just be which you don’t have to worry about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will end up getting 呼吸機 therapy irrespective of alterations in your trouble.
As with most CPAP machines, automatic CPAP machines are made 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 as the minimum pressure and 20 cm H2O as the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might sound right. I would typically recommend making use of the default minimum and maximum pressure settings since these settings will allow for that maximum average pressure reduction and also the highest level of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you also get a machine which can be set to provide a continuing pressure just like an ordinary 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 2 varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction in the thalamus part of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive apnea, but CPAP machines may have no influence on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing 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 benefits of employing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No reason to concern yourself with adjusting a constant pressure as your condition changes
* Flexibility – the machine can be set to automatic mode or constant mode
* Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
