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 clarify the main differences. First I’ll claim that I’ve always wondered the reasons people in the industry often call an automated CPAP machine something besides what it is – 睡眠呼吸機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is a result of 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 term CPAP, however, doesn’t mean that the continuously delivered air will likely be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway in order to get rid of the obstruction and to enable you to breathe normally. What many people call “regular” CPAP machines do this by blowing air with a constant pressure through the night, no matter 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 is made to sense your breathing by using a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the other hand, if the machine senses you’re not breathing well – that is certainly, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people who have apnea breathe normally for around some area of the night, it makes sense which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in comparison with 呼吸機 which delivers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the key benefit of a computerized CPAP machine might not be the reduced average pressure, nevertheless it may simply be that you don’t need to worry about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter alterations in your trouble.
Similar to most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup from the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure may make sense. I might almost always recommend utilizing the default minimum and maximum pressure settings because these settings will allow for your maximum average pressure reduction as well as the highest amount of patient comfort.
Another great benefit of automatic CPAP machines is that they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, and you also obtain a machine which is often set to offer a constant pressure similar to a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to the people who vfwfvc using CPAP equipment for the first time.
There are two kinds of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus section 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 are suffering from obstructive apnea, but CPAP machines will have no influence on central 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 enhancing the pressure during central apnea events in which the airway is definitely open. Similarly, advanced automatic CPAP machines could 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 requirement to be worried about adjusting a constant pressure when your condition changes, Flexibility – the 睡眠呼吸機 could be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
