I am often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in the following paragraphs I’ll lay out to clarify the main differences.
First I’ll state that I’ve always wondered the reasons people in the business have a tendency to call an automatic CPAP machine something besides what it is – an automatic CPAP machine. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding of the 睡眠呼吸機. CPAP means Continuous Positive Airway Pressure, indicating that air pressure will be delivered continuously through the sleeping cycle. The word CPAP, however, doesn’t mean that the continuously delivered air will be in a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting based on your preferences is automatic CPAP machine.
A CPAP machine is designed to blow air via your partially obstructed airway to be able to remove the obstruction and to let you breathe normally. What many people call “regular” CPAP machines do this by blowing air at a constant pressure through the night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automated CPAP machine does not utilize a constant pressure. Rather, the machine was created to sense your breathing by using a pressure feedback device. Once the machine senses you happen to be breathing well, the delivered pressure will likely be lower. On the contrary, if the machine senses you’re not breathing well – that is, in the event it senses an apnea, hypopnea or snoring – the delivered pressure will likely be higher.
Because most individuals with 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 path of an evening in contrast to a CPAP machine which delivers 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 relatively low – under 10 cm H2O – the main advantage of an automatic CPAP machine may not be the reduced average pressure, nevertheless it may just be which you don’t have to worry about adjusting your pressure setting down the road. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of modifications in your condition.
Just like most CPAP machines, automatic CPAP machines are designed 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 be set. Usually default setting of 4 cm H2O since the minimum pressure and 20 cm H2O because the maximum pressure is utilized. However, in case your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure may make sense. I would personally more often than not recommend utilizing the default minimum and maximum pressure settings because these settings will permit for the maximum average pressure reduction and the highest amount of patient comfort.
Yet another excellent benefit from automatic CPAP machines is the fact they’re really two machines in just one. You get a CPAP machine which adjusts pressure automatically, therefore you get a machine which is often set to deliver a jfsqgg pressure like a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those people who are using CPAP equipment for the first time.
There are two types of sleep apnea – central and obstructive. Central sleep apnea occurs because of a dysfunction inside the thalamus part of the brain, while obstructive obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are designed to open the airway for patients that suffer from obstructive apnea, but CPAP machines could have no effect on central obstructive sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to prevent enhancing 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 defined as shallow breathing).
Below is really a review of the advantages of utilizing an automatic CPAP machine: Approximately 40% overall reduction in delivered pressure. No reason to be worried about adjusting a continuing pressure as the condition changes. Flexibility – the equipment may be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas.
