APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The ventilator circuit refers to the tubing that connects the ventilator to a patient, as well as any device that is connected to the circuit tubing. The most common devices include heaters and humidifiers, filters, suction catheters, and therapeutic aerosol generators (nebulizers and inhalers) (figure 1 and figure 2).

Detailed explanation-2: -One method of classifying anesthesia breathing systems is based on how gas flows: open, semi-open, semi-closed, and closed systems.

Detailed explanation-3: -The primary function of any breathing circuit is to deliver oxygen and anesthetic gases to a patient while eliminating carbon dioxide. Rebreathing circuits direct the expired gases through a soda lime canister for absorption of carbon dioxide, and then is rebreathed by the patient.
