Oxygen Tank Duration Formula:
| From: | To: |
The oxygen tank duration formula calculates how long an oxygen tank will last based on tank pressure, volume factor, and flow rate. This is essential for patients and healthcare providers to manage oxygen therapy effectively.
The calculator uses the oxygen tank duration formula:
Where:
Explanation: The formula calculates how long an oxygen tank will last by multiplying the tank pressure by its volume factor, then dividing by the flow rate at which oxygen is being delivered.
Details: Accurate calculation of oxygen tank duration is crucial for ensuring continuous oxygen therapy, planning for tank changes, and preventing interruptions in oxygen supply for patients who depend on it.
Tips: Enter the current tank pressure in psi, the volume factor specific to your tank type, and the prescribed flow rate in L/min. All values must be positive numbers.
Q1: What is a volume factor?
A: The volume factor is a constant specific to each type of oxygen tank that relates pressure to the actual volume of oxygen contained.
Q2: How do I find the volume factor for my tank?
A: The volume factor is typically provided by the tank manufacturer and can often be found on the tank label or in the product specifications.
Q3: Why is the result in minutes?
A: The formula calculates duration in minutes because flow rate is typically measured in liters per minute, making minutes the most practical unit for clinical use.
Q4: Does temperature affect the calculation?
A: While temperature can affect gas pressure, this calculation assumes standard conditions. For precise medical applications, consult with your healthcare provider about any necessary adjustments.
Q5: Can I use this calculator for all types of oxygen tanks?
A: This calculator works for compressed gas oxygen tanks when you use the appropriate volume factor. It may not be applicable to liquid oxygen systems.
