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’ll set out to describe the main differences. First I’ll claim that I’ve always wondered the reasons people in the industry often call an automatic CPAP machine something other than what it is – 睡眠呼吸機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion this is caused by a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air will be at a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts the pressure setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is designed to blow air using 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 that by blowing air with 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 fails to utilize a constant pressure. Rather, the equipment was created to sense your breathing through the use of a pressure feedback device. When the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the contrary, 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.
Because most individuals with apnea breathe normally for at least some part of the night, it makes sense that a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in comparison with 睡眠呼吸機 which delivers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the main advantage of an automatic CPAP machine may not be the reduced average pressure, but it may just be that you don’t have to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you may be getting optimal CPAP therapy regardless of alterations in your condition.
Similar to most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup from the machine the minimum and maximum pressures is going to be set. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since 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 making use of the default minimum and maximum pressure settings as these settings will allow for your maximum average pressure reduction and the highest level of patient comfort.
Yet another excellent benefit of automatic CPAP machines is the fact they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, and you get a machine which may be set to offer 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 the very first time.
The two main kinds of apnea – central and obstructive. Central apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive sleep 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 to prevent 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 identified as shallow breathing).
Below is actually a summary of the benefits of utilizing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No requirement to concern yourself with adjusting a constant pressure as the condition changes, Flexibility – the 睡眠呼吸機 may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
