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 explain the main differences.
First I’ll claim that I’ve always wondered the reasons people in the market have a tendency to call an automated CPAP machine something besides what exactly it is – an 氧氣機. You will sometimes 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 is going to be delivered continuously through the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will be with a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the pressure setting according to your requirements is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway in order to eliminate the obstruction and to let you breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air with a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine fails to use a constant pressure. Rather, the machine was created to sense your breathing with the use of a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure is going to be lower. On the other hand, once the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
As most individuals with obstructive sleep apnea breathe normally for about some area of the night, it makes sense that a constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in comparison with a CPAP machine which offers 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 relatively low – under 10 cm H2O – the main benefit of a computerized CPAP machine may not be the reduced average pressure, but it may just be that you simply don’t have to worry about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will end up getting 睡眠呼吸中止症 therapy regardless of changes in your trouble.
Similar to most CPAP machines, automatic CPAP machines are designed 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. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I might more often than not recommend using the default minimum and maximum pressure settings since these settings will permit for your maximum average pressure reduction as well as the highest degree of patient comfort.
Yet another excellent benefit of automatic CPAP machines is that they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which can be set to deliver a continuing pressure just like an ordinary CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to individuals who are using CPAP equipment the first time.
There are 2 types of apnea – central and obstructive. Central obstructive sleep apnea occurs due to 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 will have no impact 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 has already been open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is described as shallow breathing).
Below is actually a summary of the benefits of utilizing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No need to worry about adjusting a constant 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
