A FREE 2-Hour Live LECTURE

for Better Understanding, Clinical Application & Practical Exam Preparation
Mapleson breathing circuits are among the most frequently discussed topics in anaesthesia practical examinations – yet they are often taught as a collection of classifications, diagrams and memorised numbers.

    Why attend?

    Because Mapleson circuits are not just diagrams to memorise.
    Understand the configuration → understand the gas flow → understand the rebreathing → understand the clinical application.
    And once you understand the circuit, the viva questions become much easier.
    Join the FREE LIVE session on 15 September 2026.
    Reserve your spot and learn Mapleson breathing circuits from a practical, functional and examination-oriented perspective.

    ABOUT THE LECTURE

    Instead of simply memorising the Mapleson circuits, we will understand how they actually work, why their configurations matter, how fresh gas flow affects rebreathing, how to analyse them functionally, and how to approach their clinical testing and practical examination questions.

    Our Goal:

    By the end of the session, you should be able to look at a Mapleson circuit and understand what it is doing - rather than merely remembering its name.

    Who is this webinar for?
    Anaesthesia Postgraduates

    Especially those preparing for practical examinations, clinical examinations, viva voce, OSCEs and final postgraduate examinations.

    Anaesthesia Consultants

    For refreshing and consolidating the functional principles of Mapleson systems.

    Anaesthesia Postgraduates

    For strengthening practical understanding of breathing systems, circuit components, testing and troubleshooting.

    What will you take away from this LECTURE?

    By the end of this 2-hour session, you should have a structured approach to:

    Identify Mapleson circuits quickly
    Understand their construction and configuration
    Explain their functional mechanics
    Understand rebreathing and fresh gas flow requirements
    Compare spontaneous and controlled ventilation
    Understand the clinical significance of different Mapleson systems
    Perform and interpret practical circuit tests
    Approach the Bain circuit and Pethick test confidently
    Recognise common circuit problems
    Answer common practical and viva questions systematically
    Most importantly, you should leave with a conceptual framework that makes Mapleson circuits easier to remember and easier to explain.

    What will this LECTURE cover?

    One Comprehensive Webinar – Master the most important OSCE investigation stations through a focused, exam-oriented session designed to strengthen your clinical interpretation skills and improve your confidence in practical examinations.

    Understanding Breathing Systems

    Before diving into the individual Mapleson circuits, we will establish the basic principles required to understand their function
    • What is a breathing system?
    • Components of a breathing circuit
    • Fresh gas flow
    • Rebreathing
    • CO₂ elimination
    • Reservoir bag
    • Adjustable pressure-limiting (APL) valve
    • Functional significance of the position of components
    • How circuit configuration influences efficiency

    Mapleson Breathing Circuits - The Classification

    A systematic approach to the Mapleson classification.
    • Mapleson A
    • Mapleson B
    • Mapleson C
    • Mapleson D
    • Mapleson E
    • Mapleson F
    • How the circuits are classified
    • What determines their functional differences
    • Identifying each circuit from its diagram/configuration
    • Position of fresh gas inlet
    • Position of reservoir bag
    • Position of APL valve
    • Patient connection
    No need to blindly memorise six diagrams. We will understand the logic behind them.

    Functional Analysis of Mapleson Circuits

    This is the core of the session. Rather than learning each circuit independently, we will use functional analysis to understand what happens to inspired and expired gases during different phases of respiration.
    • What happens during inspiration?
    • What happens during expiration?
    • Where does exhaled gas go?
    • Where does fresh gas flow?
    • When does rebreathing occur?
    • What determines the amount of rebreathing?
    • Why does the required fresh gas flow differ between circuits?
    • Why are some circuits more efficient than others?
    • How does spontaneous ventilation differ from controlled ventilation?
    Special emphasis: Mapleson A vs Mapleson D Understanding why the same circuit configuration can behave very differently depending on whether the patient is breathing spontaneously or is being mechanically ventilated.

    Fresh Gas Flow Requirements

    One of the most important concepts for understanding Mapleson circuits. We will discuss:
    • Fresh gas flow and rebreathing
    • Relationship between FGF and minute ventilation
    • Approximate FGF requirements for different Mapleson systems
    • Why some circuits require higher FGF
    • Why Mapleson A is efficient during spontaneous ventilation
    • Why Mapleson D is efficient during controlled ventilation
    • The significance of the Bain circuit
    The emphasis will be on understanding the physiology behind the numbers, rather than memorising isolated values.

    Clinical Testing of Mapleson Circuits

    A circuit that looks correct may still be functionally unsafe. We will discuss how to approach the clinical testing of breathing circuits before use. Including:
    • Visual inspection
    • Checking circuit connections
    • Checking for leaks
    • Testing the reservoir bag
    • Testing the APL valve
    • Checking the fresh gas pathway
    • Assessing the integrity of the circuit
    • Detecting common circuit-related problems
    Bain Circuit Special attention will be given to the Bain circuit, including:
    • Construction
    • Principle of operation
    • Coaxial arrangement
    • Functional analysis
    • Importance of the inner tube
    • How failure of the inner tube can result in significant rebreathing
    • Clinical testing of the Bain circuit
    • The Pethick test
    • Interpretation of the test

    Clinical Uses of Mapleson Circuits

    Understanding a circuit also means knowing when and why you would choose it. We will discuss the clinical applications of the different Mapleson systems, including:
    • Spontaneous ventilation
    • Controlled ventilation
    • Paediatric anaesthesia
    • Transport and emergency situations
    • Situations where low resistance is desirable
    • Practical advantages and limitations of different systems

    Practical Examination & Viva Preparation

    A major focus of the webinar will be how Mapleson circuits are approached in the anaesthesia practical examination. We will work through the kind of questions you may encounter:
    • Identify this breathing circuit.
    • Identify the components.
    • Explain its construction.
    • Explain its working.
    • What happens during inspiration?
    • What happens during expiration?
    • What is the required fresh gas flow?
    • Is it suitable for spontaneous ventilation?
    • Is it suitable for controlled ventilation?
    • What are its advantages and disadvantages?
    • What are its clinical uses?
    • How would you test this circuit?
    • What happens if a particular component is disconnected or damaged?
    The objective: To move from “I can identify the circuit” to “I can explain, analyse, test and clinically apply the circuit.”
