Mapleson D Breathing Circuit – Anaesthesia & Respiratory Breathing System for Controlled Ventilation

The Mapleson D Breathing Circuit is a lightweight anaesthetic breathing system designed for delivering fresh gases to patients during anaesthesia and assisted or controlled ventilation. It is widely used in operating theatres and other anaesthesia environments when connected to compatible anaesthesia equipment.

The circuit typically consists of breathing tubing, a fresh gas inlet, patient connector, reservoir bag and adjustable pressure-limiting (APL) valve, although the exact configuration varies by manufacturer.
