Oxygen Calculation Tool app for iPhone and iPad

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 10 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.

The drip rate calculator can be used to assist you with med math. Enter the supply and dose information and the calculator will determine the rate in ml/hr.

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 dont 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.

***Please note, this app does NOT subtract 200 psi from initial input to account for residual O2. Some formulas may call for this. If this is desired by users, you can subtract 200 psi from your pressure prior to input.
