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 set out to explain the primary differences. First I’ll claim that I’ve always wondered why many people in the industry tend to call an automatic CPAP machine something besides what it is – 呼吸機. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding of the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously throughout the sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air is going to be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting according to your requirements is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway to be able to get rid of the obstruction and to allow you to breathe normally. What many people call “regular” CPAP machines accomplish this 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.
A computerized CPAP machine will not utilize a constant pressure. Rather, the machine is made to sense your breathing through the use of a pressure feedback device. If 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 certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
As most individuals with sleep apnea breathe normally for about some area 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 a night in comparison with 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 first time CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the primary advantage of a computerized CPAP machine will not be the reduced average pressure, nevertheless it may simply be that you don’t need to bother about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy regardless of alterations in your condition.
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 is going to be set. Normally the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O as the maximum pressure can be used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure may make sense. I might typically recommend using the default minimum and maximum pressure settings as these settings will allow for the maximum average pressure reduction as well as the highest level of patient comfort.
Another great advantage of automatic CPAP machines is that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to offer a continuing pressure similar to a regular CPAP machine. This flexibility in functionality is appealing to many CPAP users, especially to people who vfwfvc using CPAP equipment for the first time.
There are 2 varieties of obstructive sleep apnea – central and obstructive. Central apnea occurs as a result of a dysfunction within the thalamus part of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients that suffer from obstructive apnea, but CPAP machines will have no effect on central sleep apnea. Some automatic CPAP machines including 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 has already been open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is a breakdown of some great benefits of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure, No need to be worried about adjusting a constant pressure as the 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
