I’m 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 main differences.
First I’ll claim that I’ve always wondered the reasons people in the business have a tendency to call an automated CPAP machine something apart from what exactly it is – an 氧氣機. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding in the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air is going to be with a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is made to blow air using your partially obstructed airway in order to get rid of 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 entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine will not utilize a constant pressure. Rather, the machine is made to sense your breathing with the use of a pressure feedback device. If the machine senses you might 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 certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most people with apnea breathe normally for about some portion of the night, it stands to reason that the constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in comparison with a CPAP machine which offers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the main benefit from an automated CPAP machine may not be the reduced average pressure, nevertheless it may just be which you don’t need to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be getting 陽壓呼吸器 therapy regardless of alterations in your condition.
As with most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup of the machine the minimum and maximum pressures will be set. Normally the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might sound right. I would typically recommend utilizing the default minimum and maximum pressure settings because these settings will allow for the maximum average pressure reduction as well as the highest amount of patient comfort.
Another great benefit of automatic CPAP machines is the fact they’re really two machines in a single. You get a CPAP machine which adjusts pressure automatically, and you obtain a machine which can be set to deliver a continuing pressure just like a normal CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who are using CPAP equipment for the first time.
There are 2 types of sleep apnea – central and obstructive. Central apnea occurs due to a dysfunction inside the thalamus area of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive apnea, but CPAP machines may 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 to avoid enhancing the pressure during central apnea events wherein 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 a review of some great benefits of employing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No requirement to worry about 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 real difference between obstructive apneas/hypopneas and central apneas/hypopneas
