I’m often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll lay out to clarify the key differences.
First I’ll state that I’ve always wondered why many people in the industry tend to call an automated CPAP machine something other than what exactly it is – an automatic CPAP machine. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding from the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be with a constant pressure. Therefore, the appropriate term for 睡眠窒息症 which automatically adjusts pressure setting according to your preferences is automatic CPAP machine.
A CPAP machine is made to blow air via your partially obstructed airway so that you can eliminate the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air with a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
An automatic CPAP machine does not make use of a constant pressure. Rather, the machine is made to sense your breathing by using a pressure feedback device. When the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the contrary, 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 at least some portion of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in comparison with a CPAP machine which delivers a constant pressure. This reduced pressure really helps 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 benefit from a computerized CPAP machine will not be the reduced average pressure, nevertheless it may simply be which you don’t have to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy no matter modifications in your condition.
As with most CPAP machines, automatic CPAP machines are created 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 likely be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure may make sense. I would typically recommend making use of the default minimum and maximum pressure settings as these settings allows for the maximum average pressure reduction and also the highest level of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You have a CPAP machine which adjusts pressure automatically, and you get a machine which is often set to provide a continuing pressure like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to individuals who are using CPAP equipment the first time.
The two main varieties of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines will have no influence on pazbvl 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 where the airway is already open. Similarly, advanced 睡眠窒息症 could also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a summary of the benefits of utilizing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure
No requirement to worry about adjusting a continuing pressure as the condition changes
Flexibility – the equipment could be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
