7. Real-time updates: Ensure data is updated in real-time to reflect changing patient conditions.

8. Patient-friendly language: Use plain language and avoid medical jargon to facilitate patient understanding.

9. Data density: Balance data density to avoid overwhelming users while providing sufficient information.

10. Customization: Allow users to customize data display to suit their preferences and workflows.
