I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to clarify the main differences.
First I’ll state that I’ve always wondered the reasons people in the market tend to call a computerized CPAP machine something besides what exactly it is – a computerized CPAP machine. You will sometimes hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is because of a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air will likely be in a constant pressure. Therefore, the appropriate term for 睡眠窒息症 which automatically adjusts the pressure setting based on your preferences is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway to be able to eliminate 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 not.
An automated CPAP machine fails to use a constant pressure. Rather, the machine was created to sense your breathing by using a pressure feedback device. If the machine senses you are 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, when it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Because most people who have sleep apnea breathe normally for around some part of the night, it makes sense that the constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in contrast to a CPAP machine 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.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit from an automatic CPAP machine might not be the reduced average pressure, but it may just be that you simply don’t have to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of changes in your trouble.
Similar to most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup in the machine the minimum and maximum pressures will be set. Usually the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure may make sense. I would more often than not recommend making use of the default minimum and maximum pressure settings as these settings will permit for the maximum average pressure reduction and also the highest amount of patient comfort.
Yet 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 can be set to provide a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to those people who are using CPAP equipment the first time.
There are two kinds of sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction inside the thalamus area of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are made to open the airway for patients who are suffering from obstructive sleep apnea, but CPAP machines may have no impact on pazbvl obstructive sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events in which the airway is already open. Similarly, advanced 睡眠窒息症 can also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is a review of the advantages of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No reason to worry about adjusting a constant pressure as the condition changes
Flexibility – the device may be set to automatic mode or constant mode
Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
