I’m often asked the question, “What’s the difference between an automatic CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to describe the key differences. First I’ll claim that I’ve always wondered the reasons people in the industry often call an automated CPAP machine something apart from what exactly it is – 睡眠呼吸機. You will frequently hear people call these kinds of machines APAP machines or Auto-PAP machines. I believe 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 term 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 in accordance with your requirements is automatic CPAP machine.
A CPAP machine was created to blow air through your partially obstructed airway so that you can get rid of the obstruction and to allow you to breathe normally. What lots of people call “regular” CPAP machines do that by blowing air at a constant pressure through the night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise.
An automatic CPAP machine fails to make use of a constant pressure. Rather, the machine is made to sense your breathing by using a pressure feedback device. Once the machine senses you are breathing well, the delivered pressure will be lower. On the other hand, 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.
Because most people who have sleep apnea breathe normally for at least some part of the night, it stands to reason that a constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening in contrast to 呼吸機 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.
In case your prescribed pressure setting is comparatively low – under 10 cm H2O – the main benefit from 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 in the future. A computerized CPAP machine virtually guarantees you will be getting optimal CPAP therapy irrespective of changes in your trouble.
As with most CPAP machines, automatic CPAP machines are made to deliver air pressure between 4 cm H2O and 20 cm H2O. Throughout the initial setup of the machine the minimum and maximum pressures will likely be set. Usually the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since the maximum pressure can be used. However, if your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I would typically recommend making use of the default minimum and maximum pressure settings because these settings allows for your maximum average pressure reduction as well as the highest degree of patient comfort.
Yet another excellent advantage of automatic CPAP machines is the fact that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and you get a machine which may be set to deliver a constant pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who vfwfvc using CPAP equipment the first time.
There are 2 varieties of sleep apnea – central and obstructive. Central obstructive sleep apnea occurs because of a dysfunction in the thalamus part of the brain, while 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 central sleep apnea. Some automatic CPAP machines like the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid improving the pressure during central apnea events where the airway is definitely open. Similarly, advanced automatic CPAP machines can also differentiate between central and obstructive hypopnea (which is identified as shallow breathing).
Below is a summary of the advantages of utilizing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure, No requirement to concern yourself with adjusting a continuing pressure when your condition changes, Flexibility – the 睡眠窒息症 could be set to automatic mode or constant mode. Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
