## Description

GUS is a focused gastric ultrasound calculator for clinicians using point-of-care ultrasound to estimate gastric volume.

Enter antral cross-sectional area, patient age, and patient weight to calculate estimated gastric volume and volume per kg. GUS displays a simple low-risk or high-risk interpretation using a 1.5 mL/kg threshold.

The app includes adult and paediatric calculation modes, age-range guardrails, and quick access to formula references.

Medical disclaimer: GUS is intended for use by qualified healthcare professionals as a calculation aid only. It does not provide a diagnosis or treatment recommendation and is not a substitute for independent clinical judgement. Results depend on the accuracy of the ultrasound measurements entered and should be interpreted alongside all relevant clinical information. Users should seek or confirm advice from an appropriately qualified doctor in addition to using GUS and before making medical decisions.
