I’m often asked the question, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I’ll set out to describe the primary differences. First I’ll say that I’ve always wondered why many people in the industry tend to call an automatic CPAP machine something other than what exactly it is – 呼吸機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I think this is caused by a misunderstanding of the acronym CPAP. CPAP means 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 will be at a constant pressure. Therefore, the correct term to use for a CPAP machine which automatically adjusts the pressure setting in accordance with your preferences is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway so that you can remove the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines do that by blowing air with a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine fails to utilize a constant pressure. Rather, the equipment is designed 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 be lower. On the other hand, once the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people with obstructive sleep apnea breathe normally for at least some portion 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 a night in comparison with 睡眠窒息症 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.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the primary benefit from an automatic CPAP machine may not be the reduced average pressure, however it may just be which you don’t need to worry about adjusting your pressure setting in the future. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of alterations in your problem.
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 from the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O as the maximum pressure is utilized. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might make sense. I would more often than not recommend utilizing the default minimum and maximum pressure settings since these settings will permit for your maximum average pressure reduction and the highest level of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which is often set to provide 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.
The two main types of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction within the thalamus section of the brain, while obstructive obstructive sleep 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 will have no influence on central obstructive sleep 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 in which the airway is definitely open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is really a breakdown of the benefits of using an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure, No requirement to be worried about adjusting a continuing pressure when your condition changes, Flexibility – the 睡眠窒息症 could be set to automatic mode or constant mode. Some automatic machines detect the difference between obstructive apneas/hypopneas and central apneas/hypopneas
