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💊

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.
Delivery
