I am often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to explain the key differences.
First I’ll state that I’ve always wondered the reasons people in the market often call an automated CPAP machine something apart from what it is – an automated CPAP machine. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding in the 呼吸機. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air is going to be at a constant pressure. Therefore, the correct term 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 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 throughout the night, whether or not you’re experiencing an apnea – or cessation of breathing – or not.
A computerized CPAP machine does not make use of a constant pressure. Rather, the device is made to sense your breathing with the use of a pressure feedback device. When 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 – which is, when it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people who have sleep apnea breathe normally for around 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 course of a night in comparison with 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 new CPAP users.
Should your prescribed pressure setting is comparatively low – under 10 cm H2O – the main advantage of an automated CPAP machine will not be the reduced average pressure, but it may just be that you simply don’t have to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of changes in your problem.
As with most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup from the machine the minimum and maximum pressures will be set. Normally the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is used. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would almost always recommend using the default minimum and maximum pressure settings since these settings allows for your maximum average pressure reduction and also the highest level of patient comfort.
Yet another excellent benefit from automatic CPAP machines is that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you get yourself a machine which can be set to deliver 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 very first time.
The two main varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive apnea, but CPAP machines may have no effect on central obstructive sleep 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 where the airway is definitely open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is actually a breakdown of the advantages of using an automatic CPAP machine: Approximately 40% overall decrease in delivered pressure. No reason to worry about adjusting a continuing pressure as your condition changes. Flexibility – the machine may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
