I’m 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 set out to explain the primary differences. First I’ll say that I’ve always wondered the reasons people in the industry often call an automated CPAP machine something apart from what it is – 睡眠呼吸機. You will frequently hear people call these sorts of machines APAP machines or Auto-PAP machines. I think this is a result of a misunderstanding of 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 will be at a constant pressure. Therefore, the appropriate term to use for a CPAP machine which automatically adjusts the pressure setting based on your needs is automatic CPAP machine.
A CPAP machine was created to blow air using your partially obstructed airway in order to eliminate the obstruction and to let you breathe normally. What lots of people call “regular” CPAP machines do this by blowing air with a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
A computerized CPAP machine does not utilize a constant pressure. Rather, the device is designed to sense your breathing with the use of a pressure feedback device. When the machine senses you are breathing well, the delivered pressure will be lower. On the other hand, if 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 who have apnea breathe normally for about some part of the night, it stands to reason which a constant pressure is normally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the path of an evening compared 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 first time CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the main advantage of an automated CPAP machine might not be the reduced average pressure, but it may simply be which you don’t have to worry about adjusting your pressure setting down the road. A computerized CPAP machine virtually guarantees you will end up getting optimal CPAP therapy irrespective of modifications in your condition.
Similar to most CPAP machines, automatic CPAP machines are designed to deliver air pressure between 4 cm H2O and 20 cm H2O. During the initial setup in the machine the minimum and maximum pressures will likely be set. Usually default setting of 4 cm H2O as the minimum pressure and 20 cm H2O since 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 since these settings allows for the maximum average pressure reduction and also the highest amount of patient comfort.
Yet another excellent benefit from automatic CPAP machines is the fact that they’re really two machines in one. You get a CPAP machine which adjusts pressure automatically, and you also get yourself a machine which may be set to offer a constant pressure similar to a regular CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to those who vfwfvc using CPAP equipment the first time.
There are 2 types of apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction in the thalamus section of the brain, while obstructive obstructive sleep apnea occurs due to an obstructed airway. CPAP machines are made to open the airway for patients that suffer from obstructive apnea, but CPAP machines could have no impact on central apnea. Some automatic CPAP machines like 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 definitely open. Similarly, advanced automatic CPAP machines may also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is a summary of some great benefits of employing an automatic CPAP machine:
Approximately 40% overall decrease in delivered pressure, No reason to be worried about adjusting a continuing pressure as your condition changes, Flexibility – the 睡眠窒息症 can be set to automatic mode or constant mode. Some automatic machines detect the real difference between obstructive apneas/hypopneas and central apneas/hypopneas
