I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll set out to describe the main differences.
First I’ll claim that I’ve always wondered the reasons people in the industry have a tendency to call an automatic CPAP machine something apart from what it is – an automatic CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding in the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the entire sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air will be at a constant pressure. Therefore, the proper term to use for 睡眠窒息症 which automatically adjusts pressure setting according to your preferences is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway so that you can get rid of the obstruction and to let you breathe normally. What many people call “regular” CPAP machines do this by blowing air in a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automatic CPAP machine will not utilize a constant pressure. Rather, the machine is designed to sense your breathing with the use of a pressure feedback device. When the machine senses you are breathing well, the delivered pressure will likely be lower. On the other hand, once the machine senses you’re not breathing well – that is, when it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most individuals with sleep apnea breathe normally for around some part of the night, it stands to reason that 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 delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the primary benefit from an automatic CPAP machine may not be the reduced average pressure, nevertheless it may just be that you simply don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you will be getting optimal CPAP therapy regardless of alterations in your problem.
As with most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. Through the initial setup from the machine the minimum and maximum pressures will likely 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, should your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure could make sense. I would more often than not recommend utilizing the default minimum and maximum pressure settings as these settings allows for your maximum average pressure reduction and also the highest amount of patient comfort.
Another excellent benefit of automatic CPAP machines is that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you obtain a machine which is often set to deliver a constant pressure just like a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are bohbri CPAP equipment the first time.
The two main types of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs due to a dysfunction within the thalamus section of the brain, while obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are designed to open the airway for patients who are suffering from obstructive apnea, but CPAP machines could 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 in order to avoid increasing the pressure during central apnea events in which the airway is already open. Similarly, 陽壓呼吸器 can also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is a breakdown of the advantages of using an automatic CPAP machine: Approximately 40% overall decline in delivered pressure. No requirement to be worried about adjusting a constant pressure when your condition changes. Flexibility – the machine may be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas.
