What It Is
The Size D oxygen cylinder is the most common portable medical oxygen cylinder in EMS, prehospital care, and clinical transport. It balances capacity against portability — adequate oxygen for patient care during short transport times without the bulk of larger hospital cylinders. The CGA870 post valve is the U.S. standard for portable medical oxygen, ensuring compatibility with all standard regulators.
At 14.6 cu ft (~415 L), the D cylinder gives meaningful therapy duration across delivery scenarios. At 15 LPM (NRB or BVM reservoir) it supports ~27 minutes of high-flow oxygen — enough for most ground transports; lower flow rates for cannula or simple mask extend duration substantially.
This cylinder ships empty and must be filled with medical-grade oxygen by an authorized medical-gas supplier before use. Handle, store, and transport per CGA and DOT regulations for compressed medical gases; inspect for damage, verify fill level before patient use, and secure regulators before transport.
