HY-01 · Hydration Protocol
Hydration protocolSynthetic demo dataTarget state: GI instability · onset 4 d · prior: symptom −14%, persistence +6%, tolerance +8%Simulate on eligible patients
What it is
A 10-day hydration plan timed around dosing days: electrolyte solution schedule, fluid targets and a wearable-based dehydration alert.
How it works
Prevents the volume and electrolyte losses that turn moderate GI symptoms into toxicity and fatigue; keeps resting HR stable.
What the patient does, day by day
| Dosing days | 💊 | Electrolyte solution 500 ml before the dose, 500 ml after, 250 ml after each loose stool. |
| Every day | ✓ | Fluid target 35 ml/kg; tracked by taps in the companion. |
| Every day | ✓ | Wearable check Alert if resting HR +8 bpm over baseline for 2 days. |
