I’m often asked the question, “What’s the main 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 state that I’ve always wondered the reasons people in the business tend to call a computerized CPAP machine something besides what it is – an automatic CPAP machine. You will often hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding in the acronym CPAP. CPAP is short 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 in a constant pressure. Therefore, the correct term for 睡眠窒息症 which automatically adjusts the stress setting based on your requirements is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway so that you can eliminate the obstruction and to enable you to breathe normally. What many people call “regular” CPAP machines accomplish this by blowing air in a constant pressure throughout the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine fails to utilize a constant pressure. Rather, the machine was created to sense your breathing through the use of a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the contrary, when the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Because most people with obstructive sleep apnea breathe normally for about some part 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 path of an evening in comparison with a CPAP machine which offers a constant pressure. This reduced pressure helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
Should your prescribed pressure setting is fairly low – under 10 cm H2O – the key advantage of a computerized CPAP machine might not be the reduced average pressure, nevertheless it may just 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 modifications 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. Throughout the initial setup from the machine the minimum and maximum pressures will likely be set. Usually the default setting of 4 cm H2O because the minimum pressure and 20 cm H2O because the maximum pressure is used. However, if your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure could make sense. I might more often than not recommend using the default minimum and maximum pressure settings because these settings allows for that maximum average pressure reduction and the highest level of patient comfort.
Yet another excellent advantage 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 also obtain a machine which may be set to provide a continuing pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to individuals who are using CPAP equipment the first time.
There are two varieties of apnea – central and obstructive. Central obstructive sleep apnea occurs due to a dysfunction in the thalamus section of the brain, while obstructive obstructive sleep apnea occurs because of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive apnea, but CPAP machines will have no impact on pazbvl 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 where the airway has already been open. Similarly, advanced 睡眠呼吸機 can also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a breakdown of some great benefits of utilizing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure
No requirement to worry about adjusting a constant pressure as the condition changes
Flexibility – the machine can be set to automatic mode or constant mode
Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
