Seeking Pulse-ox Engineer/Mathematician

07/05/2015 7:22 PM

Hello--

I work for a startup company looking for a mathematician/engineer familiar with pulse oximetry, especially data analysis (as opposed to hardware design). If interested in this work-for-hire opportunity, please private message me.

Thanks,

Brian

P.S. I hope this post doesn't violate forum policies. If it does, can you advise of another online resource I can use?

Probably best if you had posted in the below section, but that's ok.

http://cr4.globalspec.com/section/engineering-careers

Probably a good idea to post a general location also as this is an international forum (unless the work can be done long distance).

Thanks, Jack of all Trades.

Yes, the work can be done from any location. We are a "virtual company" so coordinating with someone online will work fine.

Looks like my post was moved to the Careers section.

Thanks again!

Wouldn't this require a medical doctor ? I mean the number falls between 95 and 99 if ok, and not ok out of this range...this is assuming the patient is breathing room air and not on oxygen...but there are any number of medical conditions or environmental effects or other contributing factors that could come into play...I don't see there is any data analysis without appropriate medical training and background...or are you looking for certification for an existing, or to be developed design, beyond what already exists?

Thanks, SolarEagle.

We have MD advisors/specialists who are taking care of defining the parameters of the algorithm. For clarification, we are not using pulse-ox devices with ready-made software that conducts data analysis. We need someone who can help us write the mathematical algorithm that performs the required calculations using raw data input. It's our understanding that this is relatively straight-forward but happens to be outside our collective area of expertise.

From your reply, you appear to have familiarity with pulse-ox. Any chance you'd be interested or can recommend someone?

Thanks again.

OK yes I think I get the picture, sadly I don't think I can be of any help here, but I do wish you success in this endeavor...

The only way a new non-invasive O2 sat. product can easily penetrate the prospective market is to have an enhanced accuracy without using any fudge factor in its algorithm! If you plan to use Infrared technology to implement your goal, then look for a solution that will not be using any correction factors in order to display an acceptable O2 saturation values...

As SE stated in his earlier comments and I concur, another MD doing clinical research that has an EE background will be more preferable, will be useful to your product than just a data manipulator! An individual possessing a good /sound understanding why Not all red cells in our body are functional and therefore not able to carry oxygen!

Thanks, VSAR.

I understand where you are coming from but I think some assumptions are being made that don't fit our scenario (and I'm unable to discuss in a forum such as this). Hope to identify an engineer with full understanding and appreciation of pulse-oximetry. A research-oriented MD is certainly an option, too, but that's impractical (not going to be a freelancer, for one).

For our intended purpose, we have expertise for the medical and hardware aspects. Thus, seeking a mathematician/computational expert who hopefully is familiar with pulse-oximetry.

So, anyone reading this thread that's intrigued, please don't be scared off by calls for an MD.

Thanks again.

All I can suggest is for you to attend the AAMi convention to get more information and probably meet some attendees that may be of interest both ways in your project.. From experience there are a lot of those kind of individuals or attendees that may fit what you are looking for?

I believe there is an AAMI meeting scheduled to be held in Colorado this year... Good luck!

Thanks for the info, VSAR!

Unfortunately, the 2015 AAMI conference was held about a month ago. That would have been an excellent resource. I checked AAMI's online "find an expert" tool; might be a lead or two there.

Thanks again.

So, instead of posting here, why aren't you on the phone to your local technical recruiters? I don't even know which country you're in!

Thanks for the reply, Crabtree.

Located in the USA.

Some advantages to engaging someone directly (not using recruiters, etc). Some potential disadvantages, too. Giving the internet a chance.

Thanks again.

If you can find the right person without using a recruiter, you will save a pile of money. Recruiters may have a bigger pile of resumes to pick from, but many of them don't have a clue. Their goal is to find a warm body to fill an opening, even if it's a square peg for a round hole.

Thanks, Tribefan1952 (is that a Cleveland reference? I have Ohio roots and am a huge baseball fan).

As a startup, saving a pile of money is definitely desirable. Ultimately, we need to find someone dedicated and qualified so if my online search falters, we will pursue other options.

I think a widely cast net such as an online search might succeed in finding someone who is particularly enthusiastic, which would be a bonus to finding a square peg for our square hole.

Thanks again.

Yes, BrianSD. I too am from the Cleveland area and a huge baseball fan! The year I was born is also cleverly concealed in my stage name. I don't know anything about pulse oximetry, other than what I learned today when I googled it. Interesting technology. I think they put one of those on my finger during my recent colonoscopy. If you need a good statistician/mathematician to accurately crunch some experimental data, you might want to consider asking for help at a local college. I taught evening classes at a local community college for many years. I was pleasantly surprised at the high level of expertise and competence of the math faculty there.

Thanks for the reply, Tribe. My family roots are in Columbus. Earliest memories of sports are my Dad yelling at TV during OSU v UM football but I formed my team allegiances while growing up in the Bay Area. So....I'm a Giants and Warriors fan...sorry, was our turn first! One of my favorite broadcasters is Duane Kuiper, who tells some great tales of his days with Cleveland. BTW, the recent Bauer at-bat was phenomenal.

Pulse-ox is fairly new to me, too. Relatively simple technology that's been around for a long time and is now a core function for many monitoring and diagnostic processes. Did you come across the report that the Apple Watch includes a pulse-ox (Apple CMO is from a pulse-ox company)?

A student is a great idea (I thought about a grad student) but there are a cpl reasons we prefer someone with greater experience and credentials.

Thanks again!

Bauer was hilarious! I was thinking more about seeking out a math professor with expertise in statistics and experimental design.

Yes, a professor would be tremendous, especially if ad hoc so free and clear to pursue a "side project." Thanks again!

Since you are very much interested about oxymtery, you may want to research on Nellcor technical specifications.. Their product, although it has some built in fudge factors, has been adopted as one of the standards in the industry since the mid 80s....

By the way, nellcor has been bought by Puritan bennett just before I retired and by now could have been also acquired by a much bigger entity? Knowing /understanding or just matching their technical specifications may be worth your time?

Also, I'm sorry about the late antiquated AAMI information. That only showed how old I am!

Great ideas, VSAR. Thanks again.

Nellcor is now owned by Medtronic. Nellcor is one of the "big 4" pulse-ox OEMs.

I've come across some industry spec sheets (tried contacting their authors, in fact) but haven't googled expressly for spec sheets. Would be worthwhile to do that; thanks for the suggestion.

And, absolutely no apologies needed re: AAMI meeting. Appreciate the heads up and idea. I hadn't heard of AAMI before so that was a very useful piece of info. If things go well for us, we might be attending in 2016!

Lastly, if having the wrong date for something is indicative of age, I'm on my last legs...and some in my family would say I'm on borrowed time. :)

Thanks again.

Pardon me for coming late to this party, but is this not a case of reinvention of the wheel? I can remember buying effective pulse oximeters for our anaesthetic department in the late 1980s and there have been decades of steady improvements since then. The infra-red absorption spectra of oxygenated and deoxygenated haemoglobin are well determined. Even studies with carboxyhaemoglobin and methaemoglobin have already been done. What other data have you to analyse?

Thanks for the reply, PHP. Sorry for my late reply.

The mathematics/equations are not necessarily ground-breaking themselves. They are part of a project that is novel. And, there is no off-the-shelf solution for the required equations/analyses that meets our needs. In this public forum, that's all I can say.
