I am often asked the issue, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the primary differences.
First I’ll claim that I’ve always wondered why many people in the industry tend to call an automatic CPAP machine something besides what exactly it is – an 氧氣機. You will often 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 be delivered continuously through the sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will be at a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts pressure 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 remove the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do that 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 not.
A computerized CPAP machine does not make use of a constant pressure. Rather, the device is designed to sense your breathing through the use of a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure will likely be lower. On the other hand, if the machine senses you’re not breathing well – that is certainly, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people who have sleep apnea breathe normally for about some part of the night, it stands to reason which a 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 really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the key advantage of a computerized CPAP machine may not be the reduced average pressure, but it may simply be that you don’t have to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you may be getting 陽壓呼吸器 therapy irrespective of modifications in your problem.
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 in the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I would personally more often than not recommend using the default minimum and maximum pressure settings since these settings will permit for that maximum average pressure reduction as well as the highest amount of patient comfort.
Another excellent benefit of automatic CPAP machines is that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, therefore you get yourself a machine which can be set to provide a constant pressure just like a regular 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.
There are 2 kinds of apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive obstructive sleep apnea, but CPAP machines could have no influence on central obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events where 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 actually a breakdown of the benefits of utilizing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No need to concern yourself with adjusting a constant pressure when 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
