This is the second lesson in a 6 part series of lessons on hemodynamics principals as they related to nursing knowledge, monitoring, and management. We strive for hemodynamics made easy!
In this lesson we talk about the concept and end goal of our hemodynamics; the delivery of oxygen. We break down and explain the delivery of oxygen equation to build understanding of the various components that factor in to the end result of perfusing oxygenated blood to our organs. The goal of this lesson is to make sure that you have a high level overview understanding of what the components are that play a role in the delivery of oxygen to our tissues as well as the importance of each of those components.

Fantastic course, many thanks.
This is a great review course!
Glad you think so!
Thank you so much, this video is so helpful.
Great lesson. Thank you so muchhhh
Would be really useful to have a video explaining oxygen concentrations, flow rates, entrainment, and the various oxygen delivery devices, etc. Seems like a basic topic to know how much oxygen you're giving but I still haven't found a good way to truly understand it :S
Thanks for the suggestion. Let me think on all that and see if theres something I can add to the todo list.
@@ICUAdvantage Thanks! Once I read about how a patient's own peak inspiratory flow rate affects the FiO2 they take in (i.e. 15L of '100% O2' versus the actual FiO2 for the patient depending on whether they're at rest or with increased work of breathing), I realised there was more to understanding the topic than I'd learned about in medical school
Awesome video! Thank you!!!!
Youre welcome!
Thanks !!!
Amazing lesson 🙂
Thank you! 😃
thankyou
You're welcome!
By your definition, is CaO2 the same as a-vO2?
Another question: cardiac index isn't used often within my field, and thus it doesn't make sense to me. I would See two population-matched people, (say two males both at 230 pounds and 45 years old) but one has a body fat percentage of 12% and the other has 38%. What I gathered from your presentation about CI is there were no morphological differences since it merely accounts for mass alone; not muscle quality and vascularization.
Its body surface area that is derived from height and weight and then used for the calculation. It isn't perfect, but less prone to variances such as these and better adapted towards a common value scale.
👌🏻👌🏻
3:01 formula for arterial oxygen content should be (Hb x 1.34 x SaO2) + (0.003 x PaO2)
There are differing sources. Either way, the difference is negligible
Isn't it 1.34?
Some sources use 1.34 and some use 1.39 from what I've found. Ultimately though they numbers are very close and give the same picture of the greater importance of the Hgb and saturation in the overall calculation.
ICU Advantage k thanks
Do seu cartão do seu cartão e do Zé do Zé do seu irmão para todos vcs aí e muito difícil né minha
That 1.39 should be 1.34 brother
Depends on the source. Both are used
