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.
