I’m often asked the question, “What’s the real difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to describe the main differences. First I’ll claim that I’ve always wondered the reasons people in the industry often call an automatic CPAP machine something besides what exactly it is – 睡眠呼吸機. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I think 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 term CPAP, however, doesn’t mean that the continuously delivered air is going to be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is made to blow air through your partially obstructed airway in order to remove the obstruction and to enable you to breathe normally. What many individuals call “regular” CPAP machines do that by blowing air with a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or not.
An automatic CPAP machine fails to 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 are breathing well, the delivered pressure will 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 will likely be higher.
Because most individuals with obstructive sleep apnea breathe normally for about some part of the night, it makes sense that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of a night in comparison with 呼吸機 which offers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the main benefit of an automatic CPAP machine may not be the reduced average pressure, however it may simply be which you don’t need to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of changes 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. Throughout 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 since the maximum pressure can be used. However, in case your prescribed pressure setting is well above 10 cm H2O then improving the minimum pressure might make sense. I would personally typically recommend utilizing the default minimum and maximum pressure settings since these settings will allow for the maximum average pressure reduction and the highest level of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in a single. You have a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which can be set to provide a constant pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to the people who vfwfvc using CPAP equipment the very first time.
There are 2 kinds of obstructive sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients that suffer from obstructive 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 in order 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 really a breakdown of some great benefits of using an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No need to concern yourself with adjusting a continuing pressure as the condition changes, Flexibility – the 睡眠窒息症 can be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
