I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll lay out to describe the key differences.
First I’ll say that I’ve always wondered why many people in the industry have a tendency to call an automatic CPAP machine something other than what it is – a computerized CPAP machine. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding of the 睡眠呼吸機. CPAP stands for 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 in a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts the pressure setting in accordance with your needs is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway so that you can eliminate the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines accomplish 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 automatic CPAP machine will not use a constant pressure. Rather, the device is made to sense your breathing through the use of a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure is going to be lower. On the contrary, when the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people who have sleep apnea breathe normally for about some part of the night, it stands to reason that the constant pressure is usually 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 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 relatively low – under 10 cm H2O – the primary benefit from a computerized CPAP machine might not be the reduced average pressure, however it may simply be which you don’t have to worry about adjusting your pressure setting in the future. An automatic CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of modifications in your trouble.
Just like most CPAP machines, automatic CPAP machines are made 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 as the minimum pressure and 20 cm H2O because the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure could make sense. I might almost always recommend utilizing the default minimum and maximum pressure settings because these settings allows for that maximum average pressure reduction and the highest level of patient comfort.
Another great benefit from automatic CPAP machines is the fact they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which is often set to provide a jfsqgg pressure similar to a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who are using CPAP equipment the first time.
There are 2 varieties of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction inside the thalamus section of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive sleep apnea, but CPAP machines will have no influence on central obstructive sleep apnea. Some automatic CPAP machines including 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 is definitely open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a breakdown of some great benefits of utilizing an automatic CPAP machine: Approximately 40% overall decline in delivered pressure. No need to worry about adjusting a continuing pressure as your condition changes. Flexibility – the device may be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas.
