SPO Medical 7500 Pulse / Oximeter

Profox has the SPO 7500 listed as a supported device so there is an option to the bundled TEMEC software. Also there is a utility that I can get my hands on that will allow you to download raw data into Excel and plot graphs automatically. I will try to figure out how to put it on the web for all of you 7500 owners.

I like it much better than the TEMEC software and it is extremely easy to use!

Don’t ask me how I got the software but it is from SPO Medical.

Send an email to skymano2@gmail.com and I will email the simple but sweet 7500 program.

I wonder if that software would work for those of us stuck with "old technology" Nellcor N-395 units, and we want to download to a computer instead of just reading the display, and we built up a cable for connecting to the computer but still have no software to grab the raw data?.....
Hypothetically speaking.

Last night my SPO 7500 gave up the ghost. I had it for a week or so and collected data during the night for the third time and when I went to turn it off this morning and download it to the software program, it would not turn off or go into communication mode to the software. So I called the tech support, which is covered by a very nice individual, and he told me that the on-off switch was bad and would have to be exchanged under warranty. He said they have 300-400 units out into the field now and 5 or so have the same problem that I have.

I have waited to supply a user testimonial until I have used the device for a week or so, and will wait to do so until the new unit gets here. UPS arrives tomorrow to pick up the old one and they will send me a new one.

As an aside, has anyone had a problem like I have in installing the aforementioned software?

I turned the 7500 on and switched to connections mode. I plugged it into the USB2 port and opened Vitabase. After filling-out the Create New Study screen, I clicked OK. I got a popup box that said "Please check connection and switch to connection mode." Anyone else have this problem?

After you have recorded your data during your sleep period, right click on your name in the bar at the top created when you entered your night time session, and after attaching one end of the USB cable to the pulse ox 7500 and the other end to a USB port on your computer, press the right switch next to the on/off button until "Cn" comes up on the display, and in the drop down box click on attach recording, and the unit will download your data and populate the pre-analysis chart.

Previous post was me.

Yes.

But in my case the cause and the fix were embarassingly simple. The "Cn" mode only lasts something like maybe half a minute before it reverts back to record mode. (Sorry, the unit is at a friend's house for the night or I would do the experiment to see exactly how long that timeout is). I suspect that the timeout is less that what it takes to fill in the New Study screen. You might want to check if it is still in connection mode when it is misbehaving. Hope it is as simple as that.

The answer was simple, once I re-read the instructions. I wasn't holding right hand button down long enough to go into communications mode.

I talked to the SPO gent. He suggested I wear the oximeter for a minimum of 5.5 min and then call him back for help in downloading.

Yesterday I did a 16 minute test drive and data download -- all okay. Then I reset the device and ran an all night study at two seconds per data point. Blood oxygen never dropped below 96%, so I feel good about the therapy and the pulse oximeter. I printed off two reports with no trouble.

The only anomaly I noticed is that I had the unit turned on for a little less than 7 hours, but the recording time on the printouts was slightly over 6 hours. Next time I use it, I will write down on and off times and compare them.

I have used the 7500 for three evenings. The overall result is positive, since I know where I am on blood oxygen. I did two tests with CPAP, with and without mouth taping as well as one test without CPAP to establish a baseline as well as to determine how the software (Desaturation Report) reports desaturations.

The oximeter and/or software have some bugs that need to be addressed. 1. Dates on the two latest reports are in 2013 and 2014.
2. Pulse data drops out about half way through the recording session.
3. In the three sessions I have run, the reported minutes are around 50 short of the actual minutes from machine "on" to "off."
4. On last night's run, Desaturation Report event 10 indicated a desaturation to 81% for 19 seconds. However, the Pulse Oximeter Time Test report shows a minimum desaturation of 83% for 0.1% of total recording time. It could be that this anomaly has to do with arithmetic. Specifically, 0.1% is 21.8 seconds. Since the event was less than 21.8 seconds, the software algorithms may be set to ignore time durations of less than 0.1%.

I have sent examples of the various anomalies to Eric at SPO Medical and he is in contact with the software authors.

Am I glad I bought the unit? You bet. It gives me information on how effective my CPAP therapy is. It also has allowed me to know, in quantitative terms, the benefits of mouth taping. (Lowest SpO2 dropped from 96% to 93% and mean SpO2 dropped from 98.7 to 98.0. I am not sure this amount of improvement is worth the aggravation of mouth taping. Thoughts on this anyone?)

Another interesting observation is that the desaturations reported when I have tested myself at home without CPAP (81% for 19 seconds) are less severe and less frequent than those observed during the sleep lab PSG, where I desaturated to 68% for 12 seconds. In addition, the desaturations reported in the PSG averaged 12 per hour versus 5.3 per hour in my home study. Thoughts on this anyone?

I just received a couple of hours ago my new unit replaced under warranty and will be trying it out tonight. They no longer ship the foam velcro finger cuff and say that the results are skewed incorrectly with its use. They recommend only using the sticky tape finger sensor fixators.

Anybody who doesn't use the foam velcro fixator, I would gladly purchase it from you.

Just FYI: You may still be able to get the special price from Turner Medical for the SPO 7500. Just use the Contact Us page at http://www.turnermedical.com or e-mail orders@turnermedical.com and ask if it's still available. Turner Medical asks that you do not post links to any of it's special pricing pages. The e-mail response time was only a few minutes so it's pretty painless.

I got my SPO 7500 yesterday and am now in the process of exchanging it because of a stripped case screw. Hopefully I will have a chance to try it out soon.

I must be snake bit. I went to use my warranty replacement unit last night and the sensor that attaches to the fingertip wasn't working properly. I couldn't get the red light to stay on long enough to record a reading.

Good news and bad news. The support is good. The bad news is I've had to use it too much. A third unit is on the way.
