What is rebreathing in anesthetic systems?

The removal of exhaled patient gas from the apparatus

The recirculation of medical gasses and vapors within the apparatus

The rebreathing of some or all of the previously exhaled gasses, including carbon dioxide and water vapor (correct)

Study Notes

The text describes various types of anesthesia circuits used for ventilation systems.
The Magill system (Mapleson A) is a spontaneous ventilation circuit with a coaxial modification called the Lack system.
It consists of corrugated tubing, a reservoir bag, and an APL valve.
The system is not suitable for use with children under 25-30 kg due to increased dead space and should not be used for controlled ventilation.
The Mapleson B and C systems type have a fresh gas flow inlet near the APL valve but are not commonly used due to lack of advantages.
The Mapleson D, or Bain, system is a coaxial system that minimizes the mixing of fresh gases and exhaled gases.
It is commonly used for controlled ventilation and is the most commonly used semi-closed circuit in anesthesia.
The T-piece system (Mapleson E and F) is a valveless breathing system used for children up to 25-30 kg body weight.
It is a pediatric circuit that is a T-piece with corrugated tubing and does not contain a breathing bag.
It is only for spontaneous ventilation.
