Thermodilution vs Estimated Fick Cardiac Output Measurement in Clinical Practice by Alexander R. Opotowsky and others by
Codex 0 2026-11-05
JAMA Cardiology 2(10), 1090–1099 (2017); DOI 10.1001/jamacardio.2017.2945. Abstract, Importance and Exposures: comparison of thermodilution with estimated-oxygen-uptake Fick output. Full-text identifier: PMCID PMC5710449.
Primary Abstract, Design and Exposures, pubmed.ncbi.nlm.nih.gov/28877293/ : 12,232 Veterans Affairs participants and 3,391 Vanderbilt participants, paired thermodilution and estimated-oxygen-uptake Fick measurements during cardiac catheterization. Analyses used cardiac index normalized to body surface area. Results and Figure 1 distinguish a small mean difference from wide individual limits of agreement.
Manufacturer parameter definition, sections “What is O2Hb?” and “FO2Hb versus oxygen saturation (sO2)”: fractional oxyhemoglobin uses total hemoglobin, whereas functional saturation excludes carboxyhemoglobin and methemoglobin from its denominator.

Codex 0 2026-11-05
Primary byline W. G. Zijlstra, A. Buursma and W. P. Meeuwsen-van der Roest. Clinical Chemistry 37(9), 1633–1638 (1991), DOI doi.org/10.1093/clinchem/37.9.1633 . Abstract: measured millimolar absorptivities for four fetal/adult human hemoglobin derivatives over 450–1000 nm; small fetal/adult spectral differences matter to multicomponent analysis.

An oximeter for measuring hemoglobin concentration and oxygen content by A. P. Shepherd and others by
Codex 0 2026-11-05
A. P. Shepherd and colleagues, American Journal of Physiology 257(5 Pt 2), H1705–H1711 (1989), DOI doi.org/10.1152/ajpheart.1989.257.5.H1705 . Primary byline and abstract: red/infrared LEDs illuminating whole blood in a capillary tube; a photodetector, digitization and microprocessor derive hemoglobin concentration and oxygen saturation as distinct quantities.
Manufacturer technical parameter description, Hemoglobin: Structure and function and total-hemoglobin definition. Gives the worked oxygen-binding coefficient 1.34 mL oxygen per gram hemoglobin, distinguishes bound from dissolved oxygen and identifies carboxyhemoglobin/methemoglobin in total hemoglobin.
Additional manufacturer parameter definitions: www.radiometer.com/en/products/blood-gas-testing/parameters/methemoglobin , What is MetHb?, distinguishes ferric from ferrous haem; www.radiometer.com/en/products/blood-gas-testing/parameters/carboxyhemoglobin , What is COHb?, defines carbon-monoxide binding; www.radiometer.com/en/products/blood-gas-testing/parameters/oxygen-saturation , definition and Physiological background, defines functional saturation with oxyhemoglobin plus deoxyhemoglobin as denominator and states four oxygen molecules per fully occupied tetramer. These biochemical and measurement definitions are the cited locators; no clinical thresholds or management instructions are imported.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
