I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to clarify the key differences. First I’ll say that I’ve always wondered why many people in the industry tend to call an automated CPAP machine something other than what it is – 睡眠呼吸機. You will often hear people call these types of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding of the acronym CPAP. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air is going to be at a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts the pressure 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 eliminate the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air at a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine will not utilize a constant pressure. Rather, the equipment was created to sense your breathing by using a pressure feedback device. If the machine senses you happen to 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, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people who have sleep apnea breathe normally for around some area of the night, it makes sense which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in comparison with 呼吸機 which delivers 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 primary benefit from a computerized CPAP machine may not be the reduced average pressure, however it may just be which you don’t need to worry about adjusting your pressure setting later on. An automatic CPAP machine virtually guarantees you will end up getting optimal CPAP therapy regardless of modifications in your condition.
Just like most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup from the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I would personally almost always recommend making use of the default minimum and maximum pressure settings because these settings allows for that maximum average pressure reduction and the highest level of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you also obtain a machine which is often set to provide a constant pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to people who vfwfvc using CPAP equipment for the first time.
There are 2 types of apnea – central and obstructive. Central apnea occurs because of a dysfunction within the thalamus section of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are made to open the airway for patients that suffer from obstructive sleep apnea, but CPAP machines could have no impact on central sleep apnea. Some automatic CPAP machines such as 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 has already been open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a review of the benefits of using an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure, No need to worry about adjusting a constant pressure as your condition changes, Flexibility – the 睡眠呼吸機 may be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
