support@zedcardio.comDoes ZED Cardio store patient information?
ZED Quick Tools calculate locally in the browser and do not save or transmit entered values. The app is designed for non-identifiable sessions; see the privacy policy for details.
Where can I find the calculation reference?
Each web result displays its selected formula and source. The app provides additional reference information within supported modules.
Why might my result differ from another tool?
Results can differ when tools use different formulas, reference populations, units or rounding. Confirm the selected method and check the original publication and your local practice.
Can I use ZED Cardio for clinical decisions?
ZED Cardio provides calculation and reference support for appropriately trained users. It does not replace clinical judgement, local guidance, specialist review or formal reporting systems.
