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 clarify the primary differences. First I’ll claim that I’ve always wondered the reasons people in the industry tend to call an automated CPAP machine something apart from what exactly it is – 睡眠窒息症. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion 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 imply that the continuously delivered air is going to be at a constant pressure. Therefore, the correct term for a CPAP machine which automatically adjusts the pressure setting according to your needs is automatic CPAP machine.
A CPAP machine is designed to blow air using your partially obstructed airway to be able to eliminate the obstruction and to let you breathe normally. What many people 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 otherwise not.
An automated CPAP machine does not utilize a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure will likely be lower. On the contrary, when the machine senses you’re not breathing well – that is certainly, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
As most people who have obstructive sleep apnea breathe normally for around some portion of the night, it makes sense that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in comparison with 睡眠呼吸機 which delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
If your prescribed pressure setting is fairly low – under 10 cm H2O – the primary advantage of an automatic CPAP machine may not be the reduced average pressure, but it may simply be which you don’t need to bother about adjusting your pressure setting down the road. An automatic CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter alterations 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. During the initial setup in the machine the minimum and maximum pressures is going to be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O since 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 would personally more often than not recommend making use of the default minimum and maximum pressure settings as these settings allows for the maximum average pressure reduction and the highest degree of patient comfort.
Another great benefit of automatic CPAP machines is the fact they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, and you get a machine which can be set to provide a continuing pressure similar to 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 types of apnea – central and obstructive. Central apnea occurs as a result of a dysfunction in the thalamus part of the brain, while obstructive apnea occurs because of 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 apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events where the airway has already been open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is actually a review of some great benefits of utilizing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No reason to be worried about adjusting a continuing pressure when your condition changes, Flexibility – the 睡眠呼吸機 may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
