SPO7500 ?'s

6PtStar · Post by **6PtStar** » Wed May 21, 2008 10:47 am

To all you folks that got your SPO7500 a while back, I need help. I got mine from Med1 but have just now had time to figure it out and try to make it work. I have had a couple of folks try to help me understand what I am reading on the reports, THANKS for helping.

It seems I am having a problem getting the sensor to keep reading. The data I got this morning said it recorded 1hr13min out of 5hrs57min. What in the world am I doing wrong. I put the rubber cuff on my finger and it is mashing my finger so hard it woke me up twice. I even put a piece of tape on it so I know it is not moving or falling off my finger. The graph looked like a deep wash board with nothing but error across the bottom. Does movement totally wipe out any readings? It does say move in several places.

So far I have not gotten enough data to tell anything. The first night I did get some data with it with only about 45 min of wash board and error, but I was tring to get a base line so it was with my O2 running. Last night I got almost nothing.

Anyone have any ideas?

The sensor goes on the smallest finger. Mine is on my pinky finger. The finger should not be sticking out of the end of the sensor. You can't move arond a lot with this gizmo.

This is something I had not seen mentioned before. If it kicks out every time I move or roll over or pull the covers up I may not ever get any good data. Do all the Pulse Ox meters do this, or is this just for this model? How can you trust the data if it is kicking out every few minites. I know I have times when I stay in one place more than others because I wake with the lower shoulder hurting but last night was a bit restless but 1 hour out of 6 is a bit much.

In addition to many nights I have worn my SPO7500 several days at work and even with my daughter at the playground. I get very few motion artifacts.

You should not need to mash your finger or tape in on. I found moving to a different finger helped when it was pinching my original finger.

Do you have your fingernail under the little fingernail on the sensor? Any chance you have it upside down? You should be able to put it on your finger and see it boot and then start displaying current information.

Do you get multiple reports or just one? I find if I take off the sensor and then put it back on I get multiple reports.

I suggest you contact SPO support they have been extremely helpful.

Funny, the website says SPO 7500 says that model you can do jumping jacks with it on (not really) as opposed to other types of oximeters. I seem to recall talking to those folks and them telling me to NOT move around to ensure the readings are more accurate.

Thanks for the info. I do wear it with the wire comming out the bottom of the thimble and my finger is not sticking out the end. Yes when I moved it to a different finger I got a seperate report but it was just as bad. I am making an assumption that movement is causing the problem because it says I had 4 hrs and 43.5 Min of undefined motion. Here is what the report looks like.

Have any of you got one that looks like this? Recording only 1 hour out of 6. What else could cause the errors shown on the bottom?

I may contact customer support tomorrow and see if they have any answers. So far the information is worthless.

Looking back through my recording I see a few with 10% in the motion summary. Most are closer to 4%.

Interesting on yours the motion summary indicates
44.7 min 12.5%
while the recording info indicates 4 hours 43.5 minutes of undefined/motion.
I don't know how to reconcile those two.

Also my report the recording info is only in minutes. I don't have a minutes and hours breakout. There are a few other differences in the format you posted and mine. I don't see many config options.

I am using vitabase 1.40 for pulseox. Are you using a different version?

thinking back about my post. maybe the issue is not motion but undefined.

Maybe the undefined/Motion is a total of Undefined and Motion and the motion summary is only motion. So if only 12% is motion than the question is what is the rest? I don't know what would cause an undefined response. I would contact support and see if you have a faulty unit. Maybe a loose connection??

paloa, it is version 2.0. It seems to be that it quits reading. When it makes one of those downword dips the screen displays _ _ _ with no numbers. If you wait a while it will come back on. I have whiggled all the wires and connections, but it seems to make no difference. I e-mailed support because I wanted to send a copy of the report so they could look at it. All I got back was "call us and we will discuss it with you". Seems to me the finger sensor is not reading all the time. Don't know, maybe it is defective but they did not tell me to send it in to have it checked.

My SPO-7500 has been working just fine since I replaced the original battery. I usually have a low threshold for replacing original batteries since they can be run down after sitting on the shelf for awhile.

My undefined motion always comes to less than 1 minute every time. I don't lay still all night!

I wear the finger thingie on my non-dominant hand on the middle finger with the top 1/4" of my finger beyond the thingie. I experimented to find a stable reading which matches what has been measured in my doctor's office.

Jerry - based on the problems you're having, I'd contact customer support. They've been very helpful and will probably be able to solve your problems.

glad you got it worked out Jerry ! ..only used mine a few times so far- The 15th of april i had 157 desats for 36min. total .fortunately only dropped to the 87% level for 20 sec.... seems to work best on my pinkie & stays put.. real good tool to check the rest of the family too. Tim

I bought an SPO 7500 about a year and a half ago, it only records maybe a couple hours a night, then quits. Was wondering if the newer versions have solved that problem, or if there is a fix/patch for the earlier models??? As it exists, the thing is pretty worthless.

Ric, sounds like you are having about the same luck as me. I have had a couple of nights that were better than the example but still can't get a complete night of decent readings. I had no idea that they were so sensitive to motion. Yea mindy I don't stay in one place all night either but I try to move slow as to not disturb my wife. Sure did not think that much motion would effect it.

I was a bit disapointed with the responce to the e-mail. I would have expected them to say try this and if it doesn't help give us a call. I have tried 4 different fingers with about the same success. On the t largest fingers I would wake up whith my fingers hurting like they were clamped in a vice. I have gotten a couple of half nights data. Don't understand why it will quit recording and then start again with no changes. Dont know what else to try. I guess I will try to call Tuesday but my confidence level is not to high, hope I will be suprised.

Thanks for all the information!

You have had it for quite a while. Are you still using the original battery? If you replaced the battery is it a 3.6V and not a 3.0 volt lithium? Wear it while awake and observe the readout often and see if it loses the calibration. Try moving your finger back and forth and try different fingers (or toes?) Anything over the holes where the light shines and is received on the bottom of the finger thimble? Just curious as mine works so well and records all night with hardly a loss from motion at all. The plots are almost perfect. I bought a package of 10 batteries type XL-050F from microbattery.com for $32.45 including shipping, the first day I received it. Since you are going to get it fixed in warranty, if it is not a battery, that is a pretty inexpensive investment to have spare batteries. They have a 10 year shelf life.
