Ambu Bag Oxygen Reservoir: Function & Benefits

The oxygen reservoir on an Ambu (bag-valve-mask) device is a collapsible bag storing 100% medical-grade oxygen, significantly enhancing emergency ventilation.

Key Benefits

• Higher Oxygen Concentration: Delivers ~100% O₂ vs. 21% room air, critical for severe hypoxia
• Prolonged Supply: Acts as backup reservoir for extended ventilation without frequent source changes
• Improved Ventilation Efficiency: Maintains positive pressure for better lung expansion
• Oxygen Conservation: Reduces demand on primary oxygen source during transport/limited supply
• Flow Control: Adjustable flow rate tailors therapy to patient needs

Clinical Impact

Ensures enriched, continuous oxygen delivery during resuscitation and emergencies, improving oxygenation in critical interventions.
