Circle Absorber

What is a Circle Absorber System?

A circle absorber system is a type of anesthesia machine that uses a closed breathing circuit to deliver anesthesia to patients. This system is made up of several components, including a circle breathing circuit, a carbon dioxide absorber, and a scavenging system. The circle breathing circuit is a closed loop that allows the recirculation of gas and anesthetic agents while removing exhaled carbon dioxide. The carbon dioxide absorber removes carbon dioxide from the patient's exhaled breath, while the scavenging system removes waste gases from the circuit to maintain a safe environment for the patient and the medical personnel.

Features of Circle Absorber Systems: 

1. Efficient use of anesthetic agents: Circle absorber systems allow for the recirculation of anesthetic agents, resulting in a more efficient use of these resources.
2. Closed-loop system: The circle breathing circuit is a closed-loop system that minimizes the risk of contamination and infection.
3. Carbon dioxide removal: The carbon dioxide absorber removes carbon dioxide from the patient's exhaled breath, preventing the buildup of this gas in the system.
4. Scavenging system: The scavenging system removes waste gases from the system, preventing the accumulation of these gases in the operating room.

Uses of Circle Absorber Systems:

• Anesthesia delivery: Circle absorber systems are primarily used for the delivery of anesthesia during surgery.
• Intensive care: Circle absorber systems may also be used in intensive care units to provide respiratory support for critically ill patients.
• Emergency medicine: Circle absorber systems may be used in emergency medicine to provide anesthesia and respiratory support in emergency situations.

Types of Circle Absorbers:

• Canister-based circle absorber: This type of circle absorber uses a canister filled with a chemical agent, such as soda lime, to remove carbon dioxide from the patient's exhaled breath.
• Membrane-based circle absorber: This type of circle absorber uses a membrane to remove carbon dioxide from the patient's exhaled breath. Membrane-based circle absorbers are more expensive than canister-based absorbers, but are more efficient and require less maintenance.
• Electronic circle absorber: This type of circle absorber uses electronic sensors to monitor the levels of carbon dioxide in the system and adjust the flow of gas and anesthetic agents accordingly.
