Hospital Oxygen Consumption Calculator

Estimate a hospital’s daily medical oxygen demand in litres and cubic metres from ICU and ward bed usage, and convert it into jumbo cylinders or LMO tank sizing.

Result

Metric		Value

Notes & assumptions: Litres/day = (ICU beds × ICU LPM + ward beds × ward LPM) × 60 × hours. 1 cubic metre = 1,000 L. A jumbo D-type cylinder holds ~7,000 L. Peak/surge demand can be much higher.

FAQ

How do I calculate hospital oxygen demand?

Total litres/day = (ICU beds × flow + ward beds × flow) × 60 minutes × hours of use. Divide by 1,000 for cubic metres.

How many cylinders is that?

A jumbo (D-type) cylinder holds about 7,000 litres, so divide daily litres by 7,000 for cylinders per day.

When should I consider an LMO tank or PSA plant?

High or continuous demand (large ICUs) is usually cheaper and safer served by a liquid medical oxygen tank or an on-site PSA plant.
