I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I will set out to clarify the key differences.
First I’ll claim that I’ve always wondered the reasons people in the market often call an automatic CPAP machine something besides what exactly it is – a computerized CPAP machine. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding from the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be in a constant pressure. Therefore, the proper term to use for 睡眠窒息症 which automatically adjusts the pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway to be able to remove the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do that by blowing air at a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine fails to use a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure will be lower. On the contrary, if the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Since most individuals with sleep apnea breathe normally for around 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 course of an evening in comparison with 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.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit of an automatic CPAP machine might not be the reduced average pressure, nevertheless it may just be that you simply don’t need to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of alterations in your problem.
Just like 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. Normally the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O as the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I would personally typically recommend using the default minimum and maximum pressure settings since these settings will allow for your maximum average pressure reduction and the highest degree of patient comfort.
Another excellent benefit from 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 continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are bohbri CPAP equipment for the first time.
There are two types of obstructive sleep apnea – central and obstructive. Central apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines will have no effect on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent improving the pressure during central apnea events where the airway has already been open. Similarly, 陽壓呼吸器 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 decrease in delivered pressure. No need to be worried about adjusting a constant pressure as the condition changes. Flexibility – the device can be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
