## Description

Oxygen Calculation Tool is designed for transport medical professionals. Enter your oxygen supply and a flow rate to see minutes of usable oxygen, with support for up to 10 cylinders for both portable and onboard use. You can choose a free-flow setting or a ventilation-based calculation derived from minute ventilation and FiO2, with an optional bias flow if needed.

It also includes a countdown feature that automatically updates the calculator when settings change, a drip-rate calculator to assist med math, and a reference page detailing the underlying calculations and cylinder conversion factors. If you don't see a cylinder size you need, use the feedback option to suggest additions. The app supports dark mode and rounds calculations down to the nearest minute. Note: the tool does not subtract 200 psi from the initial input; if you require this adjustment, subtract it yourself before input.
