I am 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 why many people in the business often call a computerized CPAP machine something besides what it is – an 氧氣機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding from 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 is going to be in a constant pressure. Therefore, the appropriate term for a CPAP machine which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway in order to remove the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine fails to utilize a constant pressure. Rather, the equipment is made to sense your breathing by using a pressure feedback device. If 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, when it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most individuals with sleep apnea breathe normally for around some portion of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in contrast to 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 new CPAP users.
If your prescribed pressure setting is relatively low – under 10 cm H2O – the primary advantage of an automatic CPAP machine may not really the reduced average pressure, however it may just be which you don’t need to bother about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you may be getting 睡眠呼吸中止症 therapy regardless of changes in your trouble.
Just like most CPAP machines, automatic CPAP machines are made 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 because the minimum pressure and 20 cm H2O because the maximum pressure can be used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might seem sensible. I would typically recommend making use of the default minimum and maximum pressure settings because these settings will allow for that maximum average pressure reduction and also the highest degree of patient comfort.
Another excellent advantage of automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which can be set to deliver a constant pressure just like an ordinary CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who are using CPAP equipment for the first time.
The two main varieties of sleep apnea – central and obstructive. Central apnea occurs due to a dysfunction inside the thalamus part of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines could have no impact on central 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 wherein 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 review of some great benefits of employing an automatic CPAP machine:
** Approximately 40% overall reduction in delivered pressure
* No need to be worried about adjusting a constant pressure as the condition changes
* Flexibility – the equipment can be set to automatic mode or constant mode
* Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
