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 claim that I’ve always wondered the reasons people in the industry often call an automatic CPAP machine something other than what exactly it is – 睡眠窒息症. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion 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 word CPAP, however, doesn’t imply 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 according to your preferences is automatic CPAP machine.
A CPAP machine is made to blow air using your partially obstructed airway so that you can remove the obstruction and to enable you to breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine does not use a constant pressure. Rather, the machine was created 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 contrary, if the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people who have sleep apnea breathe normally for around some portion of the night, it stands to reason that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in contrast to 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 new CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the main benefit of a computerized CPAP machine might not be the reduced average pressure, however it may just be that you simply don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy regardless of changes in your condition.
As with most CPAP machines, automatic CPAP machines are created 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 since the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure could make sense. I would more often than not recommend using the default minimum and maximum pressure settings as these settings will allow for your maximum average pressure reduction and the highest amount of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which can be set to deliver a continuing 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 the very first time.
The two main types of apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction inside the thalamus section of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients who suffer from obstructive apnea, but CPAP machines could have no effect on central sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid increasing the pressure during central apnea events where 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 really a review of some great benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No need to worry about adjusting a continuing pressure when your condition changes, Flexibility – the 睡眠呼吸機 can be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
