Try contacting technical support at each company that makes an auto cpap that you are considering. Ask them how their machine works, and then ask them to explain why you should choose theirs over their competitors. I find this technique will provide you some excellent information from which you can help base a decision on.

The next step is to research any studies that have been done to compare various auto cpaps. The last time I did this the 418 wasn't avaliable so I can't comment on it. One study I found shows that only the auto set T actually prevented apneas as effectively as a std cpap set at the 95% pressure point (the point that overcomes 95 % of a persons apneas), work with a heated humidifier, has auto altitude adjustment (also important to compensate for changes in weather), and is very quiet.
Last but not least read the forum. I have not found a single user who has not liked their autoset T.

Unfortunately if you end up being a user who dosen't respond well to one type of machine you may have to keep trying. (I haven't seen to much to indicate that this a hugh problem affecting a large number of people). Fortunately you can usually set an auto cpap to a single pressure if you have to.

The most important feature of an auto titrating cpap is that fact that the average pressure is much lower than the peak pressure. The reason that this is important is that even heated humidifiers cannot keep up with the flow demands of a cpap set at 12 cM of H2O or higher (under most conditions). With an average pressure of 5 or 5 cM of H2O both the humidifier and your body have an opportunity to keep up with the demand. The dynamic range (4cM to 20cM)is not an issue with the autoset T because of the way it works. One problem with some of the other auto cpaps is that they leave the pressure to high to long or wait to long to increase the pressure or both. Aside from whatever reasons this may or may not be good it is definately bad to keep the pressure high to long because of the humidity problem, and bad to be slow to increase it because it allows to many apneas to occour in between.
