TEMED Carbon Dioxide Gas Diffuser

The TEMED Gas Diffuser is designed for use by cardiovascular surgeons during open-heart surgical procedures to insufflate medical-grade carbon dioxide (CO₂) into the thoracic cavity. Carbon dioxide insufflation is intended to help reduce the risk of air embolism by displacing ambient air within the operative field.

During use, the diffuser tip is positioned within the thoracic cavity approximately two inches (2 in.) from the wound surface. A compatible flow regulator is used to control the delivery of CO₂, maintaining a flow rate within the recommended range of 0–10 L/min throughout the procedure.

The TEMED Gas Diffuser provides a reliable pathway for delivering medical-grade CO₂ from the gas source directly to the surgical site. Its malleable distal section allows the surgeon to precisely position the diffuser tip within the thoracic cavity to achieve optimal placement based on the surgical anatomy and procedural requirements.
