This lecture is gold, Dr. Rondon! Reminded of the good old days as your resident at the renal consult service.

[@xaviervel]

What a great lecture doctor Rondon

[@helbertrondon4622]

Thanks Xavier!

[@nathgoody5905]

Dr Rondon... Thanks a lot🇮🇳

[@kalijasin]

Thank You Dr. Rondon

What is the difference doctor between total body sodium, plasma sodium, exchangeable sodium?

[@Gnokhi]

Nice... One doubt... How does "Pressure Natriuresis" fit in this...?

[@helbertrondon4622]

Pressure natriuresis is related to BP control. It is a mechanism to maintain normal BP when changes in ECF volume and arterial BP occur.

Dr Rondon I enjoyed your lecture very much. I was wondering how you got the formula for calculating total body sodium at 0.91 g per kilogram

[@helbertrondon4622]

It is not a formula. It is the total body sodium measured with radioactive isotopes published in the literature. The literature says approx. 40 mmol/kg of body weight. So 40 mmol = 40 mmol x (1 mol/1000 mmol) x (22.9 g/1 mol of Na) = 0.91 g

Thank you!
