Question

Discuss Jackson Rees Circuit with a suitable diagram.

Hint:

Ensure the pop-off valve is properly set to avoid excessive pressure buildup in the circuit, which can lead to barotrauma.

Answer 1

The Jackson Rees circuit is a type of pediatric anesthesia circuit used for delivering inhaled anesthetic agents during surgery or medical procedures. It is designed for non-rebreathing, ensuring that the patient does not breathe back exhaled gases. This system is ideal for smaller patients, as it allows for efficient ventilation and oxygenation. The circuit includes the following components: 

1. Fresh Gas Flow (FGF): Oxygen and anesthetic gases flow into the circuit from a gas source. 

2. Reservoir Bag: Helps with ventilation and maintaining the patient's respiratory function. 

3. Valve: Ensures that the exhaled gases are not breathed back in. 

4. Pop-off Valve: Provides safety by allowing the release of excess pressure. 

The circuit works by allowing fresh gases to flow into the reservoir bag, which the patient inhales. After exhalation, the gases are expelled through the valve, and no CO2 is returned to the patient.
