I am 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 lay out to describe the key differences.
First I’ll claim that I’ve always wondered the reasons people in the business often call a computerized CPAP machine something other than what exactly it is – an automated CPAP machine. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding from the 睡眠窒息症. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the entire sleeping cycle. The term CPAP, however, doesn’t imply that the continuously delivered air will likely be at a constant pressure. Therefore, the proper term for a CPAP machine which automatically adjusts pressure setting based on your requirements is automatic CPAP machine.
A CPAP machine is designed to blow air through your partially obstructed airway so that you can remove the obstruction and to let you breathe normally. What lots of people 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 otherwise not.
An automated CPAP machine fails to use a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure is going to be lower. On the contrary, once the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people with sleep apnea breathe normally for around some part of the night, it makes sense which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening compared 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 brand new CPAP users.
If your prescribed pressure setting is fairly low – under 10 cm H2O – the primary benefit from a computerized CPAP machine might not be the reduced average pressure, however it may simply be that you don’t need to worry about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of changes in your condition.
Similar to most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup in the machine the minimum and maximum pressures is going to be set. Usually default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure could make sense. I might typically recommend using the default minimum and maximum pressure settings since these settings will permit for your maximum average pressure reduction and also the highest degree of patient comfort.
Another great advantage of automatic CPAP machines is the fact that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and you get yourself a machine which is often set to deliver a jfsqgg 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.
There are two varieties of sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients who suffer from obstructive apnea, but CPAP machines will have no effect on central obstructive sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid increasing the pressure during central apnea events wherein the airway is already open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is actually a summary of the advantages of employing an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No reason to be worried about 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.
