I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to clarify the primary differences. First I’ll say that I’ve always wondered the reasons people in the industry tend to call an automated CPAP machine something other than what exactly it is – 睡眠呼吸機. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding of the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will likely be at a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts the pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine was created to blow air through 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 this by blowing air at a constant pressure throughout the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine does not use a constant pressure. Rather, the device was created to sense your breathing with the use of a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure is going to be lower. On the contrary, if the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people who have sleep apnea breathe normally for at least some area 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 course of an evening in comparison with 睡眠呼吸機 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 fairly low – under 10 cm H2O – the main advantage of an automatic CPAP machine will not be the reduced average pressure, nevertheless it may just be which you don’t need to worry about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy regardless of alterations in your problem.
Just like most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup from the machine the minimum and maximum pressures is going to be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O as the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure may make sense. I would typically recommend using the default minimum and maximum pressure settings as these settings allows for that maximum average pressure reduction as well as the highest amount of patient comfort.
Yet another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, therefore you get a machine which may be set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those who vfwfvc using CPAP equipment for the first time.
There are two kinds of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction in the thalamus area of the brain, while obstructive apnea occurs due to 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 effect on central obstructive sleep apnea. Some automatic CPAP machines including 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 in which the airway has already been open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a summary of some great benefits of utilizing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure, No reason to concern yourself with adjusting a constant pressure when your condition changes, Flexibility – the 睡眠窒息症 can be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
