O2 Duration 2.0

O2 Duration serves as a practical tool for estimating oxygen consumption across various cylinder sizes, providing a quick approximation of the time remaining before an oxygen tank is depleted. It is particularly useful for healthcare professionals such as nurses and emergency medical technicians who regularly manage portable oxygen sources.

The application supports selection from multiple cylinder sizes, including A, B, D, E, G, H, K, and M. By inputting the current tank pressure and desired flow rate, users can obtain an estimate of oxygen duration in minutes. Furthermore, the built-in timer feature displays real-time tank pressure alongside a countdown, indicating the remaining operational time until depletion. Alerts are triggered when tank pressure drops to 500 psi or reaches zero, ensuring timely awareness of the tank’s status.

It is important to note that this tool provides an approximate duration based on input parameters and should not replace direct visualization of the oxygen cylinder gauge for determining actual pressure levels. The application should be used as an adjunct aid rather than a definitive measurement of remaining oxygen.
