I am often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I will set out to explain the main differences.
First I’ll claim that I’ve always wondered why many people in the industry have a tendency to call a computerized CPAP machine something besides what exactly it is – an 製氧機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is because of a misunderstanding in the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will be in 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 was created to blow air using your partially obstructed airway in order to get rid of the obstruction and to enable you to breathe normally. What many individuals call “regular” CPAP machines do this by blowing air in a constant pressure through the entire night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine does not make use of a constant pressure. Rather, the equipment is made to sense your breathing with the use of a pressure feedback device. When 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 – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people with apnea breathe normally for around some part of the night, it makes sense which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening in contrast to 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 first time CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the primary advantage of an automated CPAP machine may not the reduced average pressure, nevertheless it may simply be that you simply don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will end up getting 陽壓呼吸器 therapy irrespective of modifications in your problem.
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 is going to be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would personally typically recommend using the default minimum and maximum pressure settings because these settings will permit for the maximum average pressure reduction and also the highest degree of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact they’re really two machines in a single. You receive a CPAP machine which adjusts pressure automatically, and you also obtain a machine which can be set to deliver a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to individuals who are using CPAP equipment for the first time.
The two main kinds of apnea – central and obstructive. Central apnea occurs because of a dysfunction within the thalamus part of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive obstructive sleep apnea, but CPAP machines may have no effect on central obstructive sleep apnea. Some automatic CPAP machines including 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 where 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 a breakdown of the benefits of employing an automatic CPAP machine:
** Approximately 40% overall decrease in delivered pressure
* No need to concern yourself with 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 difference between obstructive apneas/hypopneas and central apneas/hypopneas
