睡眠呼吸中止症 – Look At This..

I am often asked the issue, “What’s the real difference between an automated CPAP machine and a regular CPAP machine?”, so in this post I’ll set out to explain the primary differences.

First I’ll claim that I’ve always wondered why many people in the business have a tendency to call a computerized CPAP machine something apart from what exactly it is – an 製氧機. You will often hear people call these kinds of machines APAP machines or Auto-PAP machines. In my opinion this is a result of a misunderstanding of the acronym CPAP. CPAP stands for Continuous Positive Airway Pressure, indicating that air pressure is going to be delivered continuously throughout the sleeping cycle. The word CPAP, however, doesn’t imply that the continuously delivered air is going to be in a constant pressure. Therefore, the proper term to use for a CPAP machine which automatically adjusts the stress setting according to your requirements is automatic CPAP machine.

A CPAP machine is designed to blow air using your partially obstructed airway in order to get rid of the obstruction and to enable you to breathe normally. What lots of people call “regular” CPAP machines accomplish this by blowing air with a constant pressure through the entire night, whether or not you’re experiencing an apnea – or cessation of breathing – or otherwise not.

An automatic CPAP machine fails to use a constant pressure. Rather, the equipment is designed to sense your breathing by using a pressure feedback device. If the machine senses you are breathing well, the delivered pressure will likely be lower. On the other hand, when the machine senses you’re not breathing well – which is, if it senses an apnea, hypopnea or snoring – the delivered pressure is going to be higher.

As most individuals with sleep apnea breathe normally for at least 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 path of a night in contrast to a CPAP machine which delivers a constant pressure. This reduced pressure really helps to increase patient comfort and compliance and makes CPAP therapy more tolerable for brand new CPAP users.

If your prescribed pressure setting is relatively low – under 10 cm H2O – the primary benefit of an automated CPAP machine may not be the reduced average pressure, but it may simply be which you don’t need to bother about adjusting your pressure setting in the future. An automated CPAP machine virtually guarantees you will end up getting 陽壓呼吸器 therapy regardless of changes in your problem.

Just like most CPAP machines, automatic CPAP machines are created 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 as the maximum pressure is used. However, should your prescribed pressure setting is well above 10 cm H2O then increasing the minimum pressure might sound right. I would typically recommend using the default minimum and maximum pressure settings because these settings will allow for your maximum average pressure reduction as well as the highest amount of patient comfort.

Yet another excellent benefit from automatic CPAP machines is that they’re really two machines in one. You receive a CPAP machine which adjusts pressure automatically, and you also obtain a machine which can be set to deliver a constant pressure just like an ordinary CPAP machine. This flexibility in functionality is alluring to many CPAP users, especially to individuals who are using CPAP equipment the first time.

The two main kinds of obstructive sleep apnea – central and obstructive. Central apnea occurs because of a dysfunction inside the thalamus section of the brain, while obstructive apnea occurs because of an obstructed airway. CPAP machines are created to open the airway for patients who suffer from obstructive apnea, but CPAP machines could have no impact on central sleep apnea. Some automatic CPAP machines such as the Puritan Bennett 420E can detect apneas which occur with and without cardiac osciallations in order to avoid improving the pressure during central apnea events wherein the airway is definitely open. Similarly, advanced automatic 氧氣機 can also differentiate vgaovd central and obstructive hypopnea (which is defined as shallow breathing).

Below is actually a breakdown of the benefits of utilizing an automatic CPAP machine:

** Approximately 40% overall decrease in delivered pressure

* No need to worry about adjusting a constant pressure as your condition changes

* Flexibility – the equipment can be set to automatic mode or constant mode

* Some automatic machines detect the main difference between obstructive apneas/hypopneas and central apneas/hypopneas
