There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  5. Post the cut offs in the info sec

    Hi,
    This app is very useful in practice, but not for exam revision. I need to learn some of these formulas (as lots of people do) it would be helpful to have the cut offs used in the info section so that we can revise from there or even heaven forbid calculate the scores our selves.
    Thanks

  10. Qtc by heart rate, not RR

    Hey. RR interval is directly related to heart rate but is not something I regularly calculate. The formula should allow using Rate

  13. TmP/GFR

    The Tubular PO4 Resorption (TRP) calculator would be enhanced tremendously by taking the arithmetic forward to the logical and clinically relevant conclusion: the tubular maximum resorption of phosphate, TmP/GFR. This would really benefit from an automatic calculation because TmP/GFR is calculated in two different ways depending on the TRP value.
    1. When TRP is less than 0.86, TmP/GFR is simply TRP x serum phosphate.
    2. When TRP is greater than 0.86, TmP/GFR is [serum phosphate][0.3TRP/(1-0.8TRP)

    A web calculator is here:
    http://baspath.co.uk/calculations/renal_tubular_reabsorption_of_ph.htm

    A normal range is here:
