Much better than the Gambro program

Appears to be very useful for me, being a clinical nephrologist. Easy calculation of cvvhdf dosing. Price is high for the number of formulas. An ideal add-on would be if you could calculate the replacement fluid rate that would be required to achieve a goal total effluent rate, since the replacement fluid rate is the primary variable affecting total effluent. Instead for now you need to keep plugging in different values until the calculation is close to your desired goal.

The Gambro app for crrt is a waste of 24 seconds of your life to download as it has no useful calculations. This app is much more practical and useful. Dropping the price and adding the above option would easily make this a five star app for me.
