Product Overview
The Size D oxygen cylinder is the most common portable medical oxygen cylinder used in EMS, pre-hospital care, and clinical transport environments. Balancing capacity against portability, the D cylinder provides 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 medical oxygen regulators.
At 14.6 cubic feet (approximately 415 liters) of medical oxygen at standard pressure, the Size D cylinder provides meaningful oxygen therapy duration across clinical delivery scenarios. At 15 LPM (non-rebreather mask or BVM reservoir), the cylinder supports approximately 27 minutes of high-flow oxygen — sufficient for most ground transport scenarios. Lower flow rates for nasal cannula or simple face mask extend duration significantly.
This cylinder ships empty and must be filled with medical-grade oxygen by an authorized medical gas supplier before use. Oxygen cylinders must be handled, stored, and transported in accordance with CGA and DOT regulations for compressed medical gases. Always inspect cylinders for damage, verify fill level before patient use, and ensure regulators are properly secured before transport.
