Description for ventilator circuit 

A breathing circuit ventilator is a medical device used to deliver oxygen, remove carbon dioxide, and deliver inhalational anaesthetic agents to a patient. Originally developed for use in anaesthesiology, many variants of breathing system are in clinical use, but most comprise a source of fresh gas flow, a length of ventilator tubing to direct the gas, an adjustable pressure limiting valve to control pressure of ventilator circuit within the system and direct waste away, and a reservoir bag to allow assisted ventilation.

There are different ventilator circuit types, each having somewhat different mechanisms of action. They have traditionally been classified by the way in which the ventilator circuit kit interacts with fresh air from the surrounding atmosphere, and by whether the patient re-breathes gases that they have previously exhaled. However, there is no international standard for classifying breathing systems, and the terms "semi-open" and "semi-closed" may cause confusion in particular between US and British usage. Strictly speaking, the term "circuit" is only accurate in the case of closed systems where the breathed gas completes a full circuit.

ventilator circuit types:

  • Open circuit ventilation system: This ventilator circuit uses unrestricted ambient air as the source of fresh gas, with no boundary between the patient breathing circuit and the atmosphere. For instance, gauze soaked in ether by the open drop technique and held near the patient's face are archaic and are no longer in clinical use. They have no reservoir and no rebreathing takes place.
  • Semi systems circuit ventilation: such as the Schimmelbusch mask use ambient air as the fresh gas source, but incorporate some sort of apparatus or reservoir that restricts the of ventilator tubing set supply by creating a partial boundary with the atmosphere. No rebreathing occurs. 
  • Semi closed circuit ventilation systems: The Semi closed circuit ventilation systems have a full boundary with the surrounding atmosphere, and use a controlled source for fresh gas flow. Intake of ventilator tubing ambient air is prevented, but excess fresh gas is vented into the surrounding atmosphere. Partial rebreathing of exhaled gas can occur. 
  • Closed circuit ventilation system: It has a totally closed boundary across which no gas enters or is vented, meaning that complete rebreathing takes place.
