I’m often asked the question, “What’s the main difference between an automated 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 automatic CPAP machine something apart from what it is – 睡眠呼吸機. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I think 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 mean 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 needs is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway to be able to remove the obstruction and to allow you to breathe normally. What many individuals call “regular” CPAP machines accomplish this by blowing air in 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 fails to use a constant pressure. Rather, the device is designed to sense your breathing by using a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure will be lower. On the other hand, if the machine senses you’re not breathing well – that is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Since most people who have apnea breathe normally for around some part 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 呼吸機 which delivers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit of an automatic CPAP machine may not be the reduced average pressure, however it may simply be which you don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy no matter changes in your condition.
Similar to most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup in the machine the minimum and maximum pressures is going to be set. Usually the default setting of 4 cm H2O as 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 might typically recommend using the default minimum and maximum pressure settings as these settings will permit for the maximum average pressure reduction and also the highest level of patient comfort.
Yet another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, and you get yourself a machine which is often set to deliver a continuing pressure like a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who vfwfvc using CPAP equipment the first time.
The two main varieties of sleep apnea – central and obstructive. Central apnea occurs due to a dysfunction in the thalamus part of the brain, while obstructive apnea occurs as a result 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 obstructive 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 improving the pressure during central apnea events wherein the airway is already 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 employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure, No need to worry about adjusting a continuing 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 real difference between obstructive apneas/hypopneas and central apneas/hypopneas
