1. What is the Oxygen Tank Duration Formula?

The Oxygen Tank Duration Formula calculates how long an oxygen tank will last based on the tank's pressure, tank factor (which depends on tank size), and the flow rate being used by the patient.

2. How Does the Calculator Work?

The calculator uses the oxygen tank duration formula:

Where:

• \( \text{Tank PSI} \) — Pressure in the oxygen tank (pounds per square inch)
• \( \text{Tank Factor} \) — Conversion factor specific to the tank size
• \( \text{Flow Rate} \) — Oxygen flow rate in liters per minute

Explanation: The formula calculates how many hours of oxygen remain in a tank based on current pressure, tank characteristics, and usage rate.

3. Importance of Oxygen Tank Duration Calculation

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

4. Using the Calculator

Tips: Enter tank pressure in PSI, tank factor (specific to your tank size), and flow rate in L/min. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical tank factors?
A: Common tank factors: D cylinder = 0.16, E cylinder = 0.28, G cylinder = 2.41, H cylinder = 3.14.

Q2: How accurate is this calculation?
A: It provides a good estimate but actual duration may vary slightly due to temperature changes and regulator accuracy.

Q3: When should I refill my oxygen tank?
A: Plan to refill when the calculated duration approaches your safety margin (typically when 2 hours remain).

Q4: Does altitude affect the calculation?
A: The formula works at all altitudes as it uses pressure rather than volume.

Q5: Can I use this for liquid oxygen systems?
A: No, this formula is only for compressed gas oxygen tanks.
