I’m often asked the question, “What’s the real difference between an automatic 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 market tend to call an automatic CPAP machine something other than what exactly it is – a computerized CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding in the 睡眠窒息症. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be in a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting in accordance with your requirements is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway to be able to remove the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines do that by blowing air with a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automatic CPAP machine fails to make use of a constant pressure. Rather, the machine is made to sense your breathing through the use of a pressure feedback device. Once the machine senses you might be breathing well, the delivered pressure will likely be lower. On the other hand, when the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most people with apnea breathe normally for at least some portion of the night, it stands to reason which a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening in contrast to a CPAP machine which offers a constant pressure. This reduced pressure helps you 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 might not be the reduced average pressure, nevertheless it may simply be which you don’t have to worry about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you will be getting optimal CPAP therapy regardless of modifications in your trouble.
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 of 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 as the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure could make sense. I might almost always recommend utilizing the default minimum and maximum pressure settings since these settings allows for the maximum average pressure reduction and also the highest degree of patient comfort.
Yet another excellent benefit of automatic CPAP machines is the fact they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which can be set to offer a jfsqgg pressure like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those people who are using CPAP equipment the first time.
The two main kinds of sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction in the thalamus section of the brain, while obstructive 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 will have no impact on central apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events in which the airway is already open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a summary of the advantages of using an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No reason to concern yourself with adjusting a constant pressure as your condition changes. Flexibility – the equipment may be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
