I am often asked the question, “What’s the main difference between an automatic CPAP machine and a regular CPAP machine?”, so in this article I’ll lay out to explain the main differences.
First I’ll state that I’ve always wondered why many people in the industry have a tendency to call a computerized CPAP machine something apart from what it is – an automated CPAP machine. You will sometimes hear people call these types of machines APAP machines or Auto-PAP machines. I believe this is caused by a misunderstanding of the 呼吸機. CPAP means Continuous Positive Airway Pressure, indicating that air pressure is going to 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 proper term for a CPAP machine which automatically adjusts the stress setting in accordance with your preferences 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 let you breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air in a constant pressure through the night, no matter whether you’re experiencing an apnea – or cessation of breathing – or not.
An automatic 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. If the machine senses you are breathing well, the delivered pressure is going to be lower. On the other hand, when the machine senses you’re not breathing well – that is certainly, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.
Since most people who have obstructive sleep apnea breathe normally for around some part of the night, it stands to reason that the constant pressure is usually unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night in comparison with a CPAP machine which offers 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.
Should your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit of an automatic CPAP machine may not be the reduced average pressure, but it may just be that you don’t need to bother about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy irrespective of changes in your trouble.
Similar to most CPAP machines, automatic CPAP machines are made 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 as the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure might make sense. I would personally more often than not recommend using the default minimum and maximum pressure settings because these settings allows for your maximum average pressure reduction as well as the highest amount of patient comfort.
Yet another excellent benefit of automatic CPAP machines is the fact that they’re really two machines in just one. You receive a CPAP machine which adjusts pressure automatically, therefore you get a machine which may be set to deliver a jfsqgg pressure similar to a regular CPAP machine. This flexibility in functionality is attractive to many CPAP users, especially to those who are using CPAP equipment the first time.
There are 2 kinds of obstructive sleep apnea – central and obstructive. Central obstructive sleep apnea occurs as a result of a dysfunction inside the thalamus part of the brain, while obstructive apnea occurs due to an obstructed airway. CPAP machines are created to open the airway for patients who are suffering from obstructive apnea, but CPAP machines will have no influence 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 avoid increasing the pressure during central apnea events where the airway is definitely open. Similarly, advanced automatic CPAP machines could also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is a breakdown 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 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.
