1. What Is Oxygen Cylinder Consumption Calculation?

The oxygen cylinder consumption calculation estimates how long an oxygen cylinder will last based on current pressure, cylinder capacity factor, and flow rate. This is essential for medical oxygen therapy planning and emergency preparedness.

2. How Does The Calculator Work?

The calculator uses the oxygen cylinder duration formula:

Where:

• \( \text{Cylinder pressure} \) — Current pressure reading in psi
• \( \text{Cylinder factor} \) — Conversion factor specific to cylinder type (L/psi)
• \( \text{Flow rate} \) — Oxygen flow rate in liters per minute

Explanation: The formula calculates total available oxygen volume and divides by consumption rate to determine duration.

3. Importance Of Oxygen Duration Calculation

Details: Accurate oxygen duration calculation is crucial for patient safety, treatment planning, and ensuring uninterrupted oxygen supply during medical procedures and home care.

4. Using The Calculator

Tips: Enter current cylinder pressure in psi, cylinder factor in L/psi, and flow rate in L/min. All values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What are common cylinder factors?
A: Common factors: E cylinder = 0.28 L/psi, D cylinder = 0.16 L/psi, M cylinder = 1.56 L/psi. Check manufacturer specifications.

Q2: How accurate is this calculation?
A: Very accurate for constant flow rates. Accuracy depends on precise pressure readings and correct cylinder factor.

Q3: Why convert to hours?
A: Hours provide practical time units for medical planning and patient monitoring during oxygen therapy.

Q4: What affects calculation accuracy?
A: Temperature changes, regulator accuracy, and flow rate consistency can affect real-world duration.

Q5: Can this be used for portable oxygen?
A: Yes, the same formula applies to portable oxygen cylinders with appropriate cylinder factors.
