I’m often asked the question, “What’s the difference between an automated CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to explain the main differences. First I’ll state that I’ve always wondered why many people in the industry often call an automatic CPAP machine something apart from what exactly it is – 呼吸機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding of the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout 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 appropriate term for a CPAP machine which automatically adjusts the pressure setting based on your needs is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway in order to remove the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air with a constant pressure throughout the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine will not use a constant pressure. Rather, the equipment is designed to sense your breathing by using a pressure feedback device. When the machine senses you are breathing well, the delivered pressure will likely be lower. On the contrary, when the machine senses you’re not breathing well – which is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most people with apnea breathe normally for at least some area of the night, it makes sense which 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 contrast to 呼吸機 which delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for first time CPAP users.
In case your prescribed pressure setting is fairly low – under 10 cm H2O – the main benefit of an automated CPAP machine will not be the reduced average pressure, nevertheless it may just be that you don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will be getting optimal CPAP therapy regardless of changes in your problem.
Similar to most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup from 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, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure could make sense. I might typically recommend utilizing the default minimum and maximum pressure settings since these settings will permit for the maximum average pressure reduction and the highest level of patient comfort.
Another excellent advantage of automatic CPAP machines is the fact they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which may be set to offer a continuing pressure just like a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to people who vfwfvc using CPAP equipment the very first time.
There are two types of apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction in the thalamus section of the brain, while obstructive 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 could have no influence on central apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events where 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 utilizing an automatic CPAP machine:
Approximately 40% overall reduction in delivered pressure, No reason to worry about adjusting a continuing pressure as your condition changes, Flexibility – the 睡眠呼吸機 could be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
