Carefusion 1535-503 - Isothermal Breathing Circuit for Respiratory Support

Carefusion 1535-503 - Isothermal Breathing Circuit for Respiratory Support

The Carefusion 1535-503 is a high-performance isothermal breathing circuit engineered for optimal humidity and temperature retention during mechanical ventilation. Designed for use in critical care and surgical settings, this circuit maintains the thermal integrity of inspired gases, reducing the need for external humidification systems. It provides a closed, efficient pathway for airflow between ventilator and patient, helping improve respiratory outcomes while minimizing condensation and circuit disruption.

Key Benefits

• Isothermal Performance: Maintains gas temperature and humidity without requiring heated humidifiers

• Reduces Condensation: Helps minimize moisture buildup within the circuit, reducing contamination risks

• Improves Patient Comfort: Delivers warm, humidified air that reduces airway irritation and supports mucociliary function

• Ready-to-Use Setup: Preassembled for quick connection, saving time during emergency and routine care

• Single-Use Design: Enhances infection control by eliminating the need for reprocessing

Compatibility and Applications

• Compatible with most ICU ventilators, transport ventilators, and anesthesia machines

• Suitable for adult respiratory care in:

  • Intensive Care Units (ICU)

  • Operating Rooms (OR)

  • Emergency Departments

  • Post-operative recovery units

  • Long-term care facilities requiring ventilator support

Usage Guidelines

• Connect the circuit securely to the ventilator and patient interface

• Inspect all connections to ensure airtight seals before initiating ventilation

• Avoid excessive bending or kinking to maintain consistent airflow

• Dispose of after single use according to facility infection control protocols

Certifications, Safety Standards, and Regulatory Approvals

• FDA-cleared for clinical respiratory use

• Manufactured under ISO 13485 quality system standards

• Constructed from biocompatible, latex-free materials

• Complies with applicable ANSI/AAMI standards for respiratory systems

Comparison with Competitor Products
Unlike standard breathing circuits that rely on external heat/moisture exchangers, the Carefusion 1535-503 delivers superior passive humidification through its isothermal design. It outperforms conventional systems by reducing circuit condensation and the potential for ventilator-associated complications.

Typical User Profile and Application Scenarios
Common users include respiratory therapists, ICU nurses, anesthesiologists, and critical care physicians in:

• High-dependency ventilatory support

• Transport ventilation where heated humidifiers are not available

• Surgical settings requiring sterile, pre-warmed breathing circuits

Best Practices for Use and Maintenance

• Store in a clean, temperature-stable environment prior to use

• Inspect the circuit prior to connection for damage or blockages

• Monitor for condensation and replace if airflow becomes compromised

• Always dispose of used circuits as medical waste after patient use

Regulatory and Safety Information
The Carefusion 1535-503 adheres to strict regulatory requirements and is manufactured in accordance with FDA and international standards to ensure safe, consistent respiratory care delivery.
