I am often asked the issue, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I will set out to explain the key differences.
First I’ll say that I’ve always wondered why many people in the market tend to call an automated CPAP machine something other than what it is – an 製氧機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding in the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air will likely be with a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts the pressure setting based on your preferences is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway in order to eliminate the obstruction and to enable you to breathe normally. What many people call “regular” CPAP machines do that by blowing air in a constant pressure through the entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
An automated CPAP machine will not make use of a constant pressure. Rather, the machine was created to sense your breathing with the use of a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will likely be lower. On the other hand, when 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.
Since most people with apnea breathe normally for at least some portion of the night, it stands to reason which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night compared with a CPAP machine which delivers a constant pressure. This reduced pressure helps you 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 key benefit from an automated 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 in the future. An automated CPAP machine virtually guarantees you may be getting 呼吸機 therapy irrespective of alterations in your condition.
Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures will be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, in case your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might seem sensible. I would personally more often than not recommend utilizing the default minimum and maximum pressure settings since these settings allows for your maximum average pressure reduction and also the highest amount of patient comfort.
Another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you get yourself a machine which can be set to offer a continuing pressure just like a normal CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment for the first time.
The two main varieties of sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus section of the brain, while obstructive obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines could have no effect on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events where the airway has already been open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a review of some great benefits of using an automatic CPAP machine:
** Approximately 40% overall decline in delivered pressure
* No requirement to be worried about adjusting a continuing pressure as your condition changes
* Flexibility – the equipment can be set to automatic mode or constant mode
* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
