The Adult Bain Circuit is a coaxial breathing system used in anesthesia to deliver fresh gas to the patient while removing exhaled gases efficiently. It consists of an inner tube that carries fresh gas to the patient and an outer corrugated tube that serves as the expiratory limb. The design helps in conserving heat and moisture, making it lightweight, compact, and convenient for clinical use.
It is commonly used in anesthesia, emergency ventilation, and transport of patients requiring controlled or assisted breathing. The system is designed to minimize dead space and resistance, ensuring patient comfort and efficient gas delivery.
