Palm Sized Light Weight CPAP with Exceptional Performance

One of the smallest CPAP machines in its class, the APEX XT Auto CPAP machine is an excellent CPAP for frequent travelers that do not wish to lug around bigger CPAP machines. While the XT auto CPAP machine is light weight and smaller in stature than other comparable CPAP machines, it delivers the sleep apnea therapy that you have become accustomed to with other Auto CPAP machines. Providing some of the newest CPAP therapy features like leak compensation, altitude adjustment, and data collection via an SD card for easy to read information that can be stored and shared with your physician.

Pressure Variation Algorithm

Designed to help relieve discomfort and pressuring during your exhale, the Pressure Variation Algorithm - PVA will automatically reduce pressure based on three different settings, ensuring that the prescribed pressure is delivered when the CPAP therapy patient needs it most. The PVA will return to your set pressure setting on the inhale so that your comfort and therapy is never compromised during use.

Auto Adjusting Algorithm

The APEX XT Auto CPAP machine will automatically adjust air pressure to the most comfortable, and lowest, levels during CPAP therapy without sacrificing the effectiveness that you are used to. The auto adjust allows for you to sleep comfortably throughout the night.

User Friendly Interface

Easy to read with an LCD display, the interface is user friendly and allows for quick adjustments of your settings. The information of your therapy is stored on an SD Card that allows for you to read it on any PC computer after uploading. The SD card also allows for you to store your information so that a physician or healthcare provider can read how effective your CPAP therapy is and make whatever necessary adjustments they, or you, see fit in order to better the therapy you receive.

Power supply already built in

No external power supply brick as it is built into the machine meaning less stuff to carry making the XT perfect for traveling. Powering the machine requires the power cord to be plugged into the wall outlet.

Reviewers Tip:

You can purchase a humidifier that attaches to this auto CPAP machine for sale, and the water chamber should always be filled with distilled water. While the water chamber may be safe in the dishwasher, there is a silicone seal that can get damaged by frequent use, shortening the life span of the chamber and causing you to replace more frequently. I recommend using a warm water and a detergent that is mild and clean your water chamber as frequently as possible. Distilled water will also help extend the life span of the chamber as it will prevent calcium build up that can happen with frequent use of tap water.

How often should I clean and replace the filter?

The grey filter that comes with the machine is washable and reusable, and should last every six months or so if it is properly maintained. Clean the filter once every two weeks at the bare minimum, and if the environment in which your Apex XT is housed is very dusty you should clean the filter more often so that you can receive the best performance from your machine.

Do I need a converter if I travel abroad?

No, you will need a special plug in order to plug in your machine, but the Apex ST can be used on international power grids, anywhere from 100 volts to 240 volts without needing to be adjusted, which makes it an ideal machine for traveling.

I was asked to write this review. Can't tell you how the machine works. I had to send it back. The instrument panel had gunk on it which, after removed, revealed permanent damage to the plastic and a cracked on/off button. I was really dismayed about the lack of quality control. These guys are very nice on the phone and so I have asked them to make sure the machine they send to me as a replacement has no manufacturing flaws, so that we don't have to go through this again. I sure hope the machine works well. This model gets great reviews. I've no idea why the one I received was all screwed up. It took two days after I made my order for the machine to be shipped. Another week to receive. It will take another week for it to get back to them in Seattle. Then I don't know how long for them to send me the replacement. but after they ship it will be another week. So overall, it will have taken well over three weeks total to receive the brand new, undamaged machine which I paid for. But these are really nice people, I know they are extremely busy, and bad things do happen. So I recommend them highly. They are a lot of fun!

Unable to set my therapy pressure by reading the owner's manual. Had to search an on-line forum to get instructions.

I suggest Respshop should include these instructions with each APEX CPAP they sell.

Easy to use and quiet.

Tricks of getting in to the automatic mode - not documented in the manual. Need to press two buttons at the same time to enter different modes.

I ended up buying two faulty XT auto CPAP machines. Both incredibly noisy, absolute rubbish.

The other day, I was talking to some patients waiting in the doctorís office about cpap machines. This is my first time using it, so I didnít know what machine to choose. My doctor just prescribed to me a cpap machine with pressure settings at 10cm.

After talking and comparing machines and prices, I have reached my decision to purchase the XT Auto, since it automatically detects at which pressures I need while asleep. I tried the cpap mode, it works fine for a few nights. Got curious and tried using the APAP mode, and I thought it is much easier for me than when it was running at fixed pressure. It seems quiet for a machine that blows air all the time when itís on. Next time, Iíll purchase a humidifier to go with it. Not bad for a machine at this price, and a free mask!

Perfect machine for traveling. I usually use a humidifier, but when I called this machine was kind of big with the humidifier. I just wanted something small. Only traveling for a few days at a time anyway right? Awesome machine.

I usually have the respironics system one auto machine, but I forgot to take it with me on my current business trip. It's a bigger machine so traveling with it hasnt always been easy. I decided to try this apex machine because it was small, they say palm sized and its really is that small, and I figured it would be easier to take with me as I am a frequent traveler for work.

I was lucky in that I could get it shipped with next day delivery, and I have used the machine for a few nights. So far I am impressed. Not sure how it will be as an every day machine like my respironics one, but seeing as I only plan on using it for travel, I would say I am really satisfied.
