I’m often asked the question, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to describe the key differences. First I’ll claim that I’ve always wondered the reasons people in the industry tend to call an automated CPAP machine something besides what exactly it is – 睡眠窒息症. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting based on your preferences is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway so that you can eliminate the obstruction and to let you breathe normally. What many people 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 not.
A computerized CPAP machine will not utilize a constant pressure. Rather, the device was created to sense your breathing by using a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will likely be lower. On the other hand, once the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most people with obstructive sleep apnea breathe normally for about some part 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 course of an evening in contrast to 睡眠呼吸機 which offers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
If 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, however it may simply be that you simply don’t have to worry about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective 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. Throughout the initial setup in the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would typically recommend utilizing the default minimum and maximum pressure settings since these settings will permit for that maximum average pressure reduction and the highest degree of patient comfort.
Another great benefit from automatic CPAP machines is that they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, therefore you get a machine which is often set to deliver a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to people who vfwfvc using CPAP equipment the very first time.
There are 2 varieties of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction within the thalamus area of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive sleep apnea, but CPAP machines could have no impact on central 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 wherein the airway is definitely open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is actually a review of the advantages of using an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No requirement to be worried about adjusting a constant pressure as your condition changes, Flexibility – the 睡眠窒息症 may be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
