SPECIFICATION:

• Type: Coaxial breathing circuit for anesthetic delivery.
• Function: Facilitates the delivery of fresh gas and the removal of exhaled gases during anesthesia.
• Application: Used in various surgical and medical procedures requiring anesthesia.

2. Components

• Outer Tube: Large-diameter corrugated tubing for expelling exhaled gases.
• Inner Tube: Small-diameter tubing within the outer tube for delivering fresh anesthetic gases.
• Fresh Gas Inlet: Connects to the anesthesia machine for gas delivery.
• Patient Connection: Typically, a 22 mm female connector for attachment to a face mask or endotracheal tube.
• Adjustable Pressure Limiting (APL) Valve: Controls pressure within the circuit, usually located near the patient end.

3. Performance

• Fresh Gas Flow Rate: Recommended flow rates are 1-3 times the patient’s minute ventilation to ensure proper gas delivery and CO2 removal.
• Pressure Range: Capable of withstanding pressures as per standard clinical requirements (up to 70 cm H2O).

4. Compatibility

• Anesthesia Machines: Compatible with most standard anesthesia machines and ventilators.
• Patient Interfaces: Suitable for use with face masks, laryngeal mask airways (LMAs), and endotracheal tubes.
