I am 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 lay out to describe the main differences.
First I’ll claim that I’ve always wondered the reasons people in the industry tend to call an automatic CPAP machine something other than what it is – a computerized CPAP machine. You will frequently hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding in the 呼吸機. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the entire sleeping cycle. The phrase CPAP, however, doesn’t mean that the continuously delivered air will be with a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the pressure setting based on your needs is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway in order to remove the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines do that by blowing air in a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
A computerized CPAP machine does not make use of a constant pressure. Rather, the device is designed to sense your breathing by using a pressure feedback device. If the machine senses you happen to be breathing well, the delivered pressure will be lower. On the contrary, once 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.
As most people who have apnea breathe normally for at least some portion 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 an evening in comparison with a CPAP machine which offers a constant pressure. This reduced pressure helps you to increase patient comfort and compliance and makes CPAP therapy more tolerable for new CPAP users.
If your prescribed pressure setting is comparatively low – under 10 cm H2O – the key benefit of an automated CPAP machine may not be the reduced average pressure, nevertheless it may just be which you don’t need to bother about adjusting your pressure setting later on. A computerized CPAP machine virtually guarantees you may be getting optimal CPAP therapy regardless of alterations in your condition.
Just like most CPAP machines, automatic CPAP machines are created to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup of the machine the minimum and maximum pressures will be set. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O as the maximum pressure is used. However, should 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 will permit for your maximum average pressure reduction and the highest degree of patient comfort.
Another excellent benefit from automatic CPAP machines is the fact they’re really two machines in a single. You have a CPAP machine which adjusts pressure automatically, and you obtain a machine which may be set to provide a jfsqgg pressure just like a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who are using CPAP equipment for the first time.
The two main types of sleep apnea – central and obstructive. Central sleep apnea occurs as a result of a dysfunction in the thalamus area of the brain, while obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are created 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 like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent increasing the pressure during central apnea events in which the airway is already open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is described as shallow breathing).
Below is a breakdown of some great benefits of utilizing an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No need to worry about adjusting a constant pressure as the condition changes. Flexibility – the equipment could be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas.
