I’m often asked the question, “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 describe the key differences.
First I’ll say that I’ve always wondered the reasons people in the business often call a computerized CPAP machine something other than what it is – a computerized CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding in the 睡眠呼吸機. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the entire sleeping cycle. The term CPAP, however, doesn’t mean that the continuously delivered air will be with a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting according to your needs is automatic CPAP machine.
A CPAP machine is made to blow air using your partially obstructed airway so that you can remove the obstruction and to let you breathe normally. What many individuals call “regular” CPAP machines do that by blowing air at a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine does not make use of a constant pressure. Rather, the equipment is designed to sense your breathing by using a pressure feedback device. When the machine senses you happen to be breathing well, the delivered pressure is going to be lower. On the contrary, once the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people who have apnea breathe normally for about some portion of the night, it stands to reason that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night compared with 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 brand new CPAP users.
If your prescribed pressure setting is fairly low – under 10 cm H2O – the primary benefit from an automatic CPAP machine will not be the reduced average pressure, however it may simply be that you don’t need to worry about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy irrespective of modifications in your problem.
As with most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures will likely be set. Normally the default setting of 4 cm H2O as the minimum pressure and 20 cm H2O as the maximum pressure is used. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure may make sense. I would personally typically recommend making use of the default minimum and maximum pressure settings because these settings will permit for the maximum average pressure reduction as well as the highest level of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and you get yourself a machine which can be set to deliver a jfsqgg pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those who are using CPAP equipment for the first time.
The two main types of apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive apnea, but CPAP machines will have no impact on central apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid improving the pressure during central apnea events in which the airway is definitely open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is a review of the benefits of using an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No reason to be worried about adjusting a constant pressure when your condition changes. Flexibility – the device could be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
