I am often asked the question, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the primary differences.
First I’ll state that I’ve always wondered why many people in the industry have a tendency to call an automated CPAP machine something apart from what it is – an 製氧機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.
A CPAP machine is made 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 this by blowing air in a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine does not use a constant pressure. Rather, the machine is made to sense your breathing by using a pressure feedback device. If the machine senses you are breathing well, the delivered pressure will likely be lower. On the other hand, once the machine senses you’re not breathing well – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Since most individuals with sleep apnea breathe normally for at least some portion of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in contrast to a CPAP machine which delivers 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.
Should your prescribed pressure setting is comparatively low – under 10 cm H2O – the key advantage of an automated CPAP machine may not really the reduced average pressure, however it may just be which you don’t have to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you may be getting 呼吸機 therapy no matter changes 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 in the machine the minimum and maximum pressures is going to be set. Usually default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would typically recommend using the default minimum and maximum pressure settings since these settings allows for that maximum average pressure reduction as well as the highest amount of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact that they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which can be set to offer a continuing pressure just like a normal CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment the first time.
There are two types of sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction in the thalamus part of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive sleep apnea, but CPAP machines will have no effect on central apnea. Some automatic CPAP machines such as 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 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is identified as shallow breathing).
Below is really a review of some great benefits of utilizing an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No need to concern yourself with adjusting a constant pressure as the condition changes
* Flexibility – the equipment can be set to automatic mode or constant mode
* Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
