1. What is the Oxygen Tank Duration Formula?

The oxygen tank duration formula calculates how long an oxygen tank will last at a given flow rate. It's essential for medical oxygen therapy planning and emergency preparedness.

2. How Does the Calculator Work?

The calculator uses the oxygen tank duration formula:

Where:

• \( \text{Tank Pressure} \) — Current pressure in the tank (psi)
• \( \text{Tank Volume} \) — Volume of the tank (L)
• \( \text{Flow Rate} \) — Oxygen flow rate (L/min)

Explanation: The formula calculates how many minutes of oxygen remain in the tank by determining the total available oxygen (pressure × volume) and dividing by the consumption rate.

3. Importance of Oxygen Tank Duration Calculation

Details: Accurate duration calculation is crucial for patient safety, ensuring continuous oxygen supply, and proper medical equipment management.

4. Using the Calculator

Tips: Enter tank pressure in psi, tank volume in liters, and flow rate in L/min. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: The calculation provides an estimate. Actual duration may vary slightly due to temperature changes, tank efficiency, and regulator performance.

Q2: What's a typical tank pressure?
A: Full medical oxygen tanks are typically pressurized to about 2000 psi, but always check your specific tank's gauge.

Q3: How do I know my tank volume?
A: Tank volume is usually marked on the tank. Common sizes are D (0.4L), E (0.7L), and M (3L) cylinders.

Q4: What if my flow rate changes?
A: Duration is inversely proportional to flow rate. Doubling the flow rate halves the duration.

Q5: Does this work for all gas tanks?
A: This formula works for oxygen and other compressed gases when using consistent units, but safety factors may apply differently.
