What is use of oxygen reservoir in an ambu bag?

The oxygen reservoir in an Ambu bag is a collapsible bag that stores extra oxygen and allows for improved oxygen delivery to a patient. Connecting it to the Ambu bag enhances oxygen therapy in several ways:

1. Increased Oxygen Concentration: The oxygen reservoir is filled with 100% medical-grade oxygen, providing a higher oxygen concentration compared to room air. When attached to the Ambu bag, the reservoir delivers this high-concentration oxygen to the patient with each ventilation, increasing the amount of oxygen delivered to the lungs. This is especially beneficial for patients with severe respiratory distress or compromised oxygenation.

2. Prolonged Oxygen Supply: The oxygen reservoir acts as a backup supply of oxygen, allowing for extended bag-mask ventilation without the need for frequent changes of oxygen sources. It provides a continuous flow of oxygen into the Ambu bag, ensuring an uninterrupted supply of oxygen to the patient during resuscitation or emergency procedures.

3. Enhanced Ventilation Efficiency: The oxygen reservoir helps maintain positive pressure in the Ambu bag, improving the efficiency of bag-mask ventilation. As the reservoir inflates, it delivers a pressurized flow of oxygen into the patient's lungs, aiding in better lung expansion and ventilation.

4. Oxygen Conservation: Using an oxygen reservoir can help conserve oxygen resources, particularly in situations where oxygen is limited or in transit. By storing a concentrated supply of oxygen, it reduces the amount of oxygen required from the main oxygen source.

5. Better Control of Oxygen Flow: The oxygen reservoir allows healthcare professionals to control the flow rate and concentration of oxygen delivered to the patient. By adjusting the flow rate, they can tailor oxygen therapy according to the patient's specific needs and respiratory status.

In summary, the oxygen reservoir in an Ambu bag provides an enriched and continuous supply of oxygen, enhancing the effectiveness of bag-mask ventilation, increasing oxygen delivery to the patient's lungs, and ensuring better oxygenation during critical medical interventions and emergencies.
