What Is The Breathing Circuit in Anesthesia?

Introduction

The disposable anesthesia breathing circuit is a respiratory support device used during anesthesia and emergency procedures. It consists of multiple components, including breathing tubes, breathing bags, breathing valves, etc. This anesthesia breathing circuit is characterized by one-time use, which avoids the risk of cross-infection and improves patient safety. At the same time, the disposable design also facilitates the operation of medical staff and reduces the workload of cleaning and disinfection. The disposable anesthesia breathing circuit mainly consists of breathing tubes, breathing bags and breathing valves. The breathing circuit is the tube that connects the patient to the ventilator and is usually made of soft material to ensure patient comfort. A breathing bag is a compressible bag used to provide storage and release of oxygen and exhaled gases. The breathing valve is used to control the flow of gas and ensure the correct delivery of oxygen and anesthetic drugs. Disposable anesthesia breathing circuits can be divided into different types according to different needs. Common types include adult and pediatric types to accommodate patients of different ages. In addition, there are some specially designed anesthesia breathing circuits, such as circuits with sputum suction function, for processing patients' respiratory secretions.

Function

First, the breathing circuit is the tube system that connects the patient to the ventilator. It is usually made of soft material with a certain degree of elasticity and durability. One end of the breathing tube is connected to the ventilator's air outlet, and the other end is connected to the patient's airway. Through the breathing circuit, the ventilator delivers oxygen and anesthetic drugs to the patient while removing the patient's carbon dioxide. Secondly, a breathing bag is a device used for manual ventilation. It is usually made of soft material and can be manually squeezed and released to provide respiratory support to the patient. One end of the breathing bag is connected to the breathing tube and the other end is connected to an airway device such as a mask or endotracheal tube. Through the breathing bag, medical staff can control the patient's respiratory rate and tidal volume to maintain the patient's respiratory function. Finally, a breathing valve is a device used to control the direction of air flow. It is usually located in the breathing circuit and can be opened or closed as needed. The breathing valve ensures the flow of oxygen and anesthetic drugs from the ventilator to the patient while preventing the patient's carbon dioxide from flowing back into the ventilator. The breathing valve can also adjust the pressure and flow rate of the airflow to suit the needs of different patients.

Clinical application

Respiratory, anesthesia and emergency equipment play an important role in the medical field, among which disposable anesthesia breathing circuits are one of the common devices in clinical applications. The disposable anesthesia breathing circuit refers to the pipeline system used to connect the anesthesia machine and the patient during anesthesia. Its main function is to provide oxygen and anesthetic drugs, and to effectively connect the patient's respiratory tract with the anesthesia machine. Disposable anesthesia breathing circuits have the following advantages. First, it reduces the risk of cross-infection. Since the instrument is only used once, it does not require cleaning and disinfection, which can avoid cross-infection caused by incomplete cleaning. Secondly, it can save time and labor costs. Traditional anesthesia breathing circuits require repeated cleaning and disinfection, and single-use instruments can save the time and labor costs of these tasks. In addition, single-use anesthesia breathing circuits can provide better airway sealing and respiratory control, thereby improving anesthesia effectiveness and patient safety. In addition, the disposable anesthesia breathing circuit can be personalized according to the needs of the patient to meet the needs of different surgeries and anesthesia methods.

Precautions

1.Choose the appropriate device: Choose a suitable disposable anesthesia breathing circuit based on the patient's needs and the doctor's recommendations. Ensure the quality and suitability of equipment.

2.Check the integrity of the device: Before use, carefully check the integrity of the disposable anesthesia breathing circuit. Make sure there are no damages, air leaks, or other issues.

3.Correctly connect the equipment: Correctly connect the disposable anesthesia breathing circuit to the anesthesia machine and ventilator. Make sure the connections are tight to avoid gas leaks.

4.Proper use: During use, medical operating regulations must be followed to ensure the correct use of disposable anesthesia breathing circuits. Avoid excessive pulling, bending or damaging the instrument.

5.Pay attention to hygiene: Disposable anesthesia breathing circuits should be sterile to ensure they are not contaminated before use. After use, waste should be disposed of correctly to avoid cross-infection. In summary, the correct use of single-use anesthesia breathing circuits is critical to patient safety and therapeutic efficacy. Medical personnel should operate in strict accordance with the operating specifications to ensure the quality and hygiene of the equipment.
