    Dear Dr Helbert, why did you stop making videos? It was really helpful. Please resume your teaching videos.

    The first two lectures in this series are basics and more important than the entire series, however the latter are clinically very important. I so wish Prof Rondon could develop a series on potassium and calcium.

    Hi, dear Helbert! 10:31 In many textboos of physiology sodium cations are said to be more impermeable than potassium (For eaxample if we talk about non-excitable cell in terms of Holdmann equation the conductance for potssium is greater than for sodium). This explains in a manner why ECF contains more sodium than ICF and opposite true for potassium. But how can it be that in conditions of hyponatremia potassium ions leaving cell more than usual? Does it necessarily mean that conductance for that ions also changes under the influence of abnormal extracellular sodium concentration? Cells are trying to save membrane potential rather than "electroneutrality" as you said, aren't they? Thank you!

      Thanks for your comment. This does not occur in hyponatremia per se unless there is also concurrent hypokalemia.

      ​​​@@helbertrondon4622thank you! And one more question😅 Edelman and Rose in their works suggest the term "total exchangeable sodium (potassium) concentration". What does "exchangable" stays for? English is not my native,so the probably obvious word in such context lacking explanation for me

    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
      @helbertrondon4622 4 роки тому

      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

  • @pietndala7394
    @pietndala7394 4 роки тому

    Somehow if low solutes intake implies low sodium intake, that will result in hypovolumiae by definition hence it must be placed in the second group but not the first!

    • @helbertrondon4622
      @helbertrondon4622 4 роки тому

      piet ndala Not really. Low Na diet does not cause hypovolemia. Yanomami Indias in the Amazon jungle ingest less than 1 mEq/day of Na their diet and have no issues. The benefit of this low Na diet for them is the prevalence of HTN is extremely low.

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

    • @helbertrondon4622
      @helbertrondon4622 4 роки тому

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