I am often asked the question, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the main differences.
First I’ll say that I’ve always wondered the reasons people in the industry have a tendency to call a computerized CPAP machine something other than what it is – an 製氧機. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding in the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts the stress setting based on your requirements is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway in order to remove the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines do that by blowing air with a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automatic CPAP machine does not use a constant pressure. Rather, the machine was created to sense your breathing through the use of 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, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most people with sleep apnea breathe normally for at least some area of the night, it makes sense that the constant pressure is normally 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 to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit of an automated CPAP machine may not really the reduced average pressure, but it may just be which you don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be getting 呼吸機 therapy regardless of changes in your trouble.
Just like most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup in the machine the minimum and maximum pressures will be set. Usually 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 increasing the minimum pressure might make sense. I might almost always recommend utilizing the default minimum and maximum pressure settings as these settings will permit for that maximum average pressure reduction and also the highest degree of patient comfort.
Yet another excellent benefit from automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which can be set to provide a constant pressure just like a normal CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to individuals who are using CPAP equipment the very first time.
The two main kinds of apnea – central and obstructive. Central 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 sleep apnea, but CPAP machines may 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 in order to avoid increasing the pressure during central apnea events in which the airway is definitely open. Similarly, advanced automatic 製氧機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is really a review of the advantages of utilizing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No reason to concern yourself with adjusting a constant pressure as your condition changes
* Flexibility – the machine can be set to automatic mode or constant mode
* Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
