Breathing Circuit – Mapleson F (Jackson Rees Modification, Paediatric)

The Mapleson F breathing circuit, also known as the Jackson Rees modification of the Ayre’s T-piece, is a semi-open anesthesia breathing system primarily designed for neonatal and paediatric patients. It allows for precise control of fresh gas flow and gentle manual ventilation, making it ideal for small patients with delicate lungs.
