I’m often asked the question, “What’s the main difference between an automated CPAP machine and a regular CPAP machine?”, so in this article I’ll lay out to describe the key 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 besides what exactly it is – a computerized CPAP machine. You will often hear people call these sorts of machines APAP machines or Auto-PAP machines. I believe this is a result of a misunderstanding in the acronym CPAP. CPAP is short for Continuous Positive Airway Pressure, indicating that air pressure will likely be delivered continuously through the sleeping cycle. The phrase CPAP, however, doesn’t imply that the continuously delivered air will likely be with a constant pressure. Therefore, the proper term for 睡眠窒息症 which automatically adjusts the stress setting in accordance with your requirements 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 enable you to breathe normally. What lots of people call “regular” CPAP machines do this by blowing air at a constant pressure through the entire night, regardless of whether you’re experiencing an apnea – or cessation of breathing – or otherwise not.
An automated CPAP machine will not make use of a constant pressure. Rather, the device is made to sense your breathing by using a pressure feedback device. If the machine senses you might be breathing well, the delivered pressure is going to be lower. On the contrary, when the machine senses you’re not breathing well – that is, if it senses an apnea, hypopnea or snoring – the delivered pressure will be higher.
Since most people who have sleep apnea breathe normally for about some area of the night, it makes sense that a constant pressure is generally unnecessary for effective CPAP therapy. Automatic CPAP machines deliver approximately 40% less pressure throughout the course of an evening compared 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 new CPAP users.
In case your prescribed pressure setting is relatively low – under 10 cm H2O – the key benefit from a computerized CPAP machine might not be the reduced average pressure, however it may simply be that you simply don’t have to worry about adjusting your pressure setting later on. An automated CPAP machine virtually guarantees you may be getting optimal CPAP therapy no matter modifications in your problem.
Similar to most CPAP machines, automatic CPAP machines are created 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. Normally the default setting of 4 cm H2O since the minimum pressure and 20 cm H2O since the maximum pressure can be used. However, should your prescribed pressure setting is well above 10 cm H2O then enhancing the minimum pressure could make sense. I might more often than not recommend using the default minimum and maximum pressure settings since these settings allows for that maximum average pressure reduction and the highest degree of patient comfort.
Another great benefit of automatic CPAP machines is the fact that they’re really two machines in one. You have a CPAP machine which adjusts pressure automatically, and you also obtain a machine which is often set to deliver a constant pressure similar to 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.
There are two varieties of obstructive sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction within the thalamus section of the brain, while obstructive obstructive sleep apnea occurs as a result of an obstructed airway. CPAP machines are made to open the airway for patients who suffer from obstructive obstructive sleep apnea, but CPAP machines could have no impact on pazbvl sleep apnea. Some automatic CPAP machines including the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations to avoid enhancing the pressure during central apnea events in which the airway has already been open. Similarly, advanced 睡眠窒息症 could also differentiate between central and obstructive hypopnea (which is defined as shallow breathing).
Below is actually a breakdown of some great benefits of employing an automatic CPAP machine:
Approximately 40% overall decline in delivered pressure
No need to concern yourself with adjusting a continuing pressure as your 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.
