What is a Breathing Circuit?

Product Category:

A Breathing Circuit is a medical device used for delivering oxygen and other gases to a patient while removing exhaled gases like carbon dioxide. The circuit is a system of components that direct the flow of gases between the patient and the support system. It is used during mechanical ventilation or anesthesia.

Disposable breathing circuits are sometimes called respiratory circuits or breathing systems. The system consists of several components, including a disposable circuit, heat & moisture exchange filter (HMEF), catheter mount, reservoir bag, and a 2-way connector.

There are different types of breathing circuits produced, including corrugated circuits, expandable circuits, and smoothbore circuits. The catheter mount, which allows for the connection to the respiratory device, is available as corrugate, expandable, or smoothbore catheter mounts.

The circuit length ensures optimal delivery of gases and a proper fit for the patient. For either adult breathing circuits or pediatric breathing circuits, there are lengths of 1.5m, 1.8m, or 2m available.

The reservoir bag acts as a temporary storage for oxygen or other gases and is available in different capacities, including 0.5L, 1L, 2L, and 3L.

AdvaCare Pharma is a trusted medical supplies manufacturer and a global exporter of Breathing Circuits. Our medical disposables are produced in strategically-located facilities spread across China, India, and the USA. Our production factories are compliant with the stringent regulations necessary for CE/ISO certification, and we regularly inspect our facilities to ensure they meet these high standards.

Product Specifications


Catheter Mount



Corrugated breathing circuit is designed to provide optimal performance and ease of use. Its lightweight and flexible construction reduces the risk of kinking which help to ensure a smooth flow of gases during respiratory procedures.

The corrugated breathing circuit allows for easy maneuverability and positioning, enhancing patient comfort and safety, while also giving efficient delivery of oxygen and anesthetic gases.


Expandable breathing circuit offers versatility and convenience in respiratory procedures. Its lightweight and flexible design allows for easy positioning and placement of equipment, providing flexibility in the location of devices away from the patient's head.

The expandable tube provides ample length to accommodate various setup configurations for breathing systems, making it suitable for a range of clinical settings.


Smoothbore breathing circuit is designed with a "tube-within-a-tube" configuration, which eliminates twisting between the inspiratory and expiratory limbs of the circuit. This unique spiral body design ensures proper alignment and prevents potential obstructions in the flow of gas. The inner wall of the tube is smooth, which reduces resistance to ventilation, and the smooth surface facilitates the collection of condensed water on the body of the tube, preventing water buildup and potential interference with gas delivery.

What is a Breathing Circuit used for?

It's used to deliver oxygen and other gases and remove carbon dioxide during mechanical ventilation or anesthesia.

How is a Breathing Circuit used?

The breathing circuit should be securely connected to the patient's endotracheal tube or tracheostomy tube.

Are there any storage instructions for Breathing Circuits?

Before use, breathing circuits should be stored in a clean and dry area, away from direct sunlight and excessive heat. It is important to prevent contamination and damage to the circuit, so it is recommended to keep them in their original packaging or in a suitable storage container.

How should Breathing Circuits be discarded after use?

After use, breathing circuits should be disposed of in accordance with local regulations for medical waste disposal. Disposable breathing circuits are usually discarded as medical waste.


What are the different types of Breathing Circuits available?

There are three types of circuits available corrugated circuits, example circuits, and smoothbore circuits. Corrugated circuits are commonly used for general ventilation. They provide flexibility, durability, and resistance to kinking. An expandable breathing circuit is similar to a corrugated one but has the additional feature of expandability. The tube can elongate or stretch to accommodate the patient's movements or positional changes during procedures or transportation. Smoothbore circuits are typically preferred in situations where lower dead space or resistance is crucial, such as for pediatric ventilation or when precise control of gas delivery is required.

Can Breathing Circuits be used for both adult and pediatric patients?

Breathing circuits are available in various sizes and configurations in order to accommodate either adults or children.

Are there any safety considerations when using a Breathing Circuit?

The proper assembly, maintenance, and monitoring of a breathing circuit are essential for the safety of the patient. It is important to follow the guidelines provided with the system and monitor for any signs of malfunction or disconnection during use.

*Regulatory compliance may vary according to production standard, import requirements and/or manufacturing origin.
