Please adjust the flow rate diagram as follows: set the range of the flow range from -80 to +80 (Right click on the diagramm title -> y-axis -> override (or the like, I have the German version running) -> Min to -80, Max to 80).  Furthermore check the button "dotted lines -> zero".

Your flow rate appears strange, but don't worry, it just appears strange.  Remember that no one can see the raw data of the flow rate (different to Respironics machines).  All of the raw data are already preprocessed by the machine in some way, unknown to us.  These processed date are than "interpreted " in a way; a first interpretation is the zero line, which is not the "real one" but already calculated.  Due to this processed data the machine calculates many parameters as the respiration rate (maybe this way): if there's a certain flank steepness above some threshold, mark it as "respiration".  But all this "calculation" and "interpretation" is not much more than anthropomancy, an ancient reading of the entrails ...  

We have no way to see if these interpretation correspond to what's really happening, besides in your case: What the machine shows cannot be related to real events: You don't have an actual respiration rate of 50.

Keep in mind that our machines are made for treatment, not for medical and scientific measurements.  (None of our machines can even detect flow limitations, because they are not built to measure such events.)

All the best,

Mike

Do you have the capability to return the one that was recording the erroneous information?  I'm really sorry you had to go through this as the result of a machine error.  In my defense, I think nearly every alarming post I made had the caveat, "if this is real", or something similar.

1.  Given it was two weeks before Christmas it was always going to be a lengthy time until it came back. I was given an identical machine to use whilst mine was being checked, at no charge.
   
2. They stated that they did not know of or have any experience with OSCAR. They stated that as such, they cannot even confirm that my machine would report properly on Oscar and as such, it is more than likely the machine is functioning fine. But as mentioned above, they took it and gave me the loan machine.
   
3. I showed them the charts indicating a constant maximum of 50 breaths per minute from my machine. I then showed them the first machine i rented from them and it showed i topped out around 38bpm and averaged around 26 0r so.
   
4. The FIRST NIGHT using the replacement machine, i topped out at 43bpm and averaged around 26bpm again. I sent a screenshot to the technician so they could see that two machines reported fine, but the machine i bought and subsequently claimed to be faulty, was showing far different numbers.
   
5. Yesterday I had a call saying i could go in and pick up a brand new machine as mine was being replaced.
