Oxygen Calculation Tool for iOS

Oxygen Calculation Tool is an app designed with transport medical professionals in mind. Once you enter your oxygen supply and a flow rate, your minutes of usable oxygen will be generated.

Oxygen Calculation Tool makes it easy to add and delete up to 3 cylinders for both the portable and onboard supply. The user also has the flexibility to enter the flow rate as a free flow setting or from ventilation settings, calculated from the minute ventilation and the FiO2 settings. Optionally, user can also enter ventilator-specific bias flow, if needed.

Oxygen Calculation Tool also has a countdown feature. This can be used to time your O2 use with your chosen settings. Using the countdown will update the settings automatically.

Oxygen Calculation Tool contains a reference page, where the math calculation used in this app is outlined, along with a list of oxygen cylinders and associated conversion factors. If you don't see a cylinder size that you need, use the feedback feature found in the settings to let me know and I will try to add it.

This app is also dark mode compatible.

Calculations are rounded down to the nearest whole minute.
