I'll cut an paste a little more info from her email shortly.

This is a LEAT with two charts.

The CVOS appears to have been completed after the first two charts.

There is a CM question on the CVOS.

Activity

P2 (thoracic)

P1 (abdominal)

EDA

Cardio

P02 (pulse oximiter - because you'll scare people if you call it a PPG)

One thing I noted was that I estimated 8-10 breaths a minute in Chart #2. That is a bit slow.

Also, the subject's cardio may have reacted a little early in chart #2---C3.

Scared to make a call, but would be suspicious of the slow breathing.

The only thing in his BI was he used THC in 2001 4x's. He said in CO they had a problem on his poly drug questions but hired him anyway. He said he was not on medications and denied using CM's. He is a 25 year old white male in good physical shape.

Also, after the charts I put the GSR's on my fingers to see about that 'weird roll' and when I did - he wouldn't look at me (btw, my GSR was fine). He didn’t question why I put the GSR’s on or anything. I must admit during the CQ’s his eyes fluttered more than on the RQ’s. I got focused on his eyes and may have missed him gently pressing his fingers. I have never seen a GSR like that and would like any interpretation. After the first chart I was irritated (internally) – but hey I am a red head! I told him to stop controlling his breathing when the second chart started. Plus there appears to have some swallowing but I didn’t witness it at the time….again I must have been focused on his eye mvmt.

I think I've posted a graphic below of CPS PO2 data. (It's an R/I chart somebody sent me. I don't have a lot to choose from here at home.) You'll see they don't filter out the slow wave changes like the other manufactures do. The Utah folks say not filtering like that is necessary; although, Limestone's PO2 data is easy to read, and they keep a constant baseline (filter). Anyhow, look at the pulses. They don't look like Donna's charts, and with Lafayette, my charts looked just like Donna's. I've never had tracings like those with the Stoelting.

I haven't had time to compare both at the same time yet, but it's on the list.

So are there any other thoughts on this guys charts. I called him INC due to manipulated distorted segments. The chief in this case will not hire him with INC/CMs. Plus I am insterested on those rolling GSRs..... guys give me some feedback..please.

Thanks to Gordon Barland for giving me feedback over the phone.

That P02 data is a lot easier to interpret.

Have you been talking to Limestone or Lafayette about this.

I know you are working on a PO2 measurement study, and I have a request.

Can you sent me the Logistic Regression Coeffecients or the Standardized Canonical Coefficients from a Discriminate Analysis for you four component and three component models.

The standardized DA coefficients are easily transformed to proportional weighting values (using the inverse of the cumulative normal distribution function) to add the P02 to OSS-3. Plus I think I know how to transform the LR coefficients to proportions - using (1-C)/(1+C). If I am correct, these two easy transformations would allow you to directly compare the coefficients from your DA and LR analysis - which is typically regarded as not all that easy.

Still, it doesn't seem natural that the EDA is influenced by respiratory activity. So, the real question is why would that occur? Its their any physiological linkeage?

Respiration is accomplished by the thoracic intercostal muscles and abdominal muscles, which are ennervated by acetylcholine in the sympathetic/peripheral nervous system, but are also regulated by sympathetic/autonomic demands in the case of respiration. EDA is ennervated by acetylcholine in the sympathetic/autonomic neurons in the skin.

I don't know enough about this to understand the mechanisms of influence between these.

Is there a possible mechanical explanation?

Where was his hand/EDA placed during the exam?

Where is hands unusually sweaty, or dry?

What does the raw EDA look like?

How tight were the EDA electrodes wrapped around his fingers?

Is there any possible medical explanation, such as some anticholinergic med or (medicinal herb) that would cause this?

In the end, its probably best not to fill in the blanks with our imaginations, just because we want an answer. We simply don't know.
