Catheter Size

Catheter size disappears after closing the app and requires the app to be deleted and redownloaded.

French size not available

You have to delete and redownload for French and gauge size to appear… so strange!

Improvements

Would love for it to show cm, not mm. Also I find our team has to delete and redownload a lot to get gauge list to appear

CVR Calc is great

This app helps clinicians to get the correct ratio between catheter and vessel.
Works great, simple to use and makes it alot easier than having to do that math manually.

Inaccurate

CVR calculations on top right = catheter to vein occupancy. There should be an option to change it and should be corrected
