Non-Rebreathing Oxygen Mask

 An  Non-Rebreathing Oxygen Mask is a high-concentration oxygen delivery device designed for emergency use in critically hypoxic patients. It features a face mask with an attached reservoir bag and a system of one-way valves to prevent the rebreathing of exhaled carbon dioxide, allowing for the delivery of up to 95% FiO2. Its safe operation depends on a minimum oxygen flow of 10-15 L/min to keep the reservoir bag inflated. It is contraindicated where uncontrolled high-flow oxygen may be harmful (e.g., in some COPD patients) and carries a severe fire risk. It is a vital, immediate-intervention tool found in all emergency response settings.

Oxygen Mask (Adult/Infant/Paediatric)

 An Oxygen Mask is a disposable, single-use interface used to deliver supplemental oxygen from a medical gas supply to a patient's airways. Available in types for specific clinical needs—Simple Mask for low-flow therapy, Venturi Mask for precise FiO2 control (especially in COPD), and Non-Rebreather Mask for emergency high-flow delivery—and in sizes for adults, children, and infants. Correct selection and application, including ensuring the proper oxygen flow rate for the mask type, are essential for effective therapy and patient safety. Adherence to strict fire safety protocols is non-negotiable due to the combustion risk posed by enriched oxygen environments.
