The Mapleson F Non-Rebreathing Circuit, also known as the Jackson-Rees circuit, is a lightweight and low-resistance breathing system designed for controlled or assisted ventilation in small animal anesthesia. Ideal for patients under 10 kg, it provides rapid gas exchange and minimal resistance, making it particularly suitable for use in puppies, kittens, and other small mammals.
Key Features:
🔹 Low Resistance System – Reduces the work of breathing in small or compromised patients
🔹 Transparent Reservoir Bag – Allows clear visualization of respiratory effort and manual ventilation
🔹 Adjustable Pressure Limiting (APL) Valve – Enables control of airway pressure and prevents barotrauma
🔹 Standard Connectors – Compatible with most veterinary anesthesia machines and masks
🔹 Flexible, Lightweight Tubing – Enhances maneuverability and comfort during procedures
Applications:
✔ Inhalation anesthesia in small animals (<10 kg)
✔ Manual or assisted ventilation during induction, maintenance, or recovery
✔ Use in veterinary clinics, mobile units, and research labs
