The Mapleson D breathing circuit is a type of anesthesia circuit commonly used in pediatric anesthesia and respiratory care. It is designed to deliver anesthetic gases and oxygen to the patient while allowing for the efficient removal of exhaled carbon dioxide. This circuit is particularly effective in controlled ventilation, making it a preferred choice in pediatric anesthesia.
The Mapleson D circuit consists of a fresh gas flow inlet near the patient’s mask or airway, a reservoir bag, and an adjustable pressure relief valve. In this system, fresh gas is continuously supplied near the patient, and exhaled gases are directed away, minimizing the rebreathing of carbon dioxide. It is especially useful in operating rooms for children and infants, where controlled ventilation is required.
The Mapleson D system provides efficient gas exchange and is lightweight, making it suitable for pediatric use. It is frequently utilized in surgeries and critical care settings to manage the airways of young patients.
