Bain Circuit

What is a Bain Circuit?
A Bain Circuit is an anaesthesia delivery system. A delivery system is an assembly of components that connects a patient’s airway to the anaesthesia machine. It creates an artificial atmosphere through which a patient breathes in and out. Bain circuits use a high fresh gas flow to deliver anaesthetic gases to the patient’s airway and to wash out the exhaled carbon dioxide. An inner tube delivers fresh gases and an outer corrugated tube serves as the outlet for exhaled gases. A Bain circuit ensures that there is no rebreathing of the exhaled gases.

Mapleson breathing systems perform the same function as that of Bain circuits. Mapleson circuits are of 6 types – A,B,C,D, E & F. Mapleson A is also called the Magill system. Mapleson D is the closest to the Bain circuit and is the classic form of the Mapleson circuit. At Smart Medical Buyer we offer you the Mapleson D, Mapleson F, Mapleson A, and Mapleson C variants.

The advantages of a Bain circuits are that they are compact and in expensive, they facilitate the scavenging of waste gases, have low dead space and offer low resistance to breathing. The major risk of using a Bain circuit is that if the inner tube breaks or is disconnected than the entire system turns into dead space. Bain circuits are in essence a co axial modification of the basic T- Piece breathing system and are recommended for controlled ventilation.

What are the main components of a Bain Circuit?

  • - Tubing: These are corrugated, flexible and low resistance.
  • - Valve: The expiratory valve is located near the reservoir bag and is opened fully or partially depending on the type of ventilation that is being administered to the patient. Types of valves include the Adjustable Pressure Limiting (APL) valve and the Heidbrink valve which is a unidirectional valve.
  • - Reservoir Bags - The anti-static reservoir bags supplied vary in capacity depending on their use i.e. for adults or paediatrics. It can be easily removed to attach a ventilator hose allowing for mechanical ventilation.
