Compatibility and Applications

The Smiths Medical 225-3709-821 anesthesia circuit is intended for adult anesthesia breathing circuit applications and is suitable for use with compatible anesthesia delivery systems, ventilatory support equipment, gas monitoring devices, and standard clinical breathing circuit accessories. Its dual-limb design is commonly used in operating rooms and procedural settings where inspiratory and expiratory pathways are managed through an anesthesia machine or compatible breathing system.

This circuit is appropriate for adult surgical procedures, procedural sedation environments, hospital anesthesia departments, ambulatory surgery centers, specialty procedure rooms, and other clinical areas where anesthesia breathing circuits with gas sampling and filtration support are required. Compatibility should always be confirmed with the facilitys anesthesia machine, monitoring equipment, connection standards, and clinical protocol before use.

Usage Guidelines

Before use, inspect the Smiths Medical 225-3709-821 anesthesia circuit packaging and components to ensure the product is intact, clean, and free from visible damage. Confirm that the circuit configuration, connections, gas sampling line, filter, elbow, wye, and breathing bag match the intended clinical setup and the requirements of the anesthesia equipment being used.

Connect the inspiratory and expiratory limbs according to the anesthesia machine manufacturers instructions and facility protocol. Attach the straight wye and temperature elbow at the patient end as required, connect the gas sampling line to the appropriate monitoring port, and verify that the bacterial and viral filter is positioned correctly for the intended application. Perform all required leak checks, flow checks, and equipment safety checks before patient connection.

This product should be used only by trained healthcare professionals familiar with anesthesia breathing circuits, respiratory monitoring, ventilation support, and institutional safety procedures. Discard after single-patient use according to facility policy and applicable waste-handling requirements.

Certifications and Safety Standards

The Smiths Medical 225-3709-821 anesthesia circuit is manufactured for professional healthcare use and should be handled in accordance with applicable medical device standards, institutional infection-control requirements, and anesthesia department policies. The bacterial and viral filter supports clinical efforts to reduce contamination risk within the breathing circuit pathway when used as directed.

Facilities should verify current product documentation, packaging information, manufacturer instructions, and regulatory status before clinical use. Healthcare teams should follow all applicable hospital policies, anesthesia safety guidelines, and manufacturer-provided instructions for setup, monitoring, use, and disposal.

Comparison with Competitors

Compared with basic adult anesthesia circuits that may require separate accessories, the Smiths Medical 225-3709-821 provides a more complete configuration by including a gas sampling port, temperature elbow, straight wye, bacterial and viral filter, 3 L breathing bag, and 10 ft male-to-male gas sampling line. This integrated setup can help reduce the need to source multiple separate components and may simplify preparation for adult anesthesia cases.

Many standard disposable anesthesia circuits offer basic breathing limb functionality but may not include the same combination of monitoring access, filtration support, and included bag and sampling line. For facilities seeking a ready-to-use adult dual-limb circuit configuration from a recognized medical device manufacturer, this Portex anesthesia circuit offers a practical balance of clinical utility, workflow efficiency, and inventory consistency.

Typical User Profile and Application Scenarios

The Smiths Medical 225-3709-821 is typically used by anesthesiologists, certified registered nurse anesthetists, anesthesia technicians, operating room nurses, respiratory therapists, and surgical support teams. It is well suited for adult patients requiring anesthesia breathing circuit support during procedures that involve controlled ventilation, assisted ventilation, gas monitoring, or manual ventilation readiness.

Common application scenarios include general surgery, outpatient procedures, hospital operating rooms, ambulatory surgery centers, endoscopy or specialty procedure suites, and anesthesia workstations that require a disposable adult dual-limb circuit with gas sampling and filtration components. The case quantity of 20 supports routine departmental stocking and procedure-based supply planning.

Best Practices for Use and Maintenance

Store the Smiths Medical 225-3709-821 anesthesia circuit in a clean, dry, temperature-appropriate area away from direct sunlight, moisture, and potential contamination. Keep the product in its original packaging until ready for use to help maintain cleanliness and product integrity.

Before each case, confirm that the correct circuit has been selected for the patient and procedure. Inspect all connections, verify correct placement of the filter and gas sampling line, and complete anesthesia machine checks according to facility protocol. During use, monitor circuit performance, ventilation parameters, gas sampling accuracy, and patient status continuously as required by clinical standards.

Do not reuse, resterilize, or attempt to reprocess a disposable anesthesia circuit unless specifically permitted by the manufacturers instructions. After use, dispose of the circuit, bag, filter, and sampling line according to institutional policy for contaminated medical waste.

Regulatory and Safety Information

The Smiths Medical 225-3709-821 is intended for professional medical use in appropriate clinical settings. It should be used only by qualified healthcare personnel trained in anesthesia delivery systems, respiratory circuit management, patient monitoring, and infection-control procedures.

Because this product is listed as latex disposable, facilities should consider patient latex sensitivity, staff safety requirements, and institutional latex policies before use. Always review the product packaging, instructions for use, and facility guidelines before patient application. Do not use the product if packaging is damaged, components are missing, connectors are compromised, or the circuit does not pass required pre-use checks.
