SPECIFICATION:

This version of the T-Piece System has a minimal dead space and low resistance to flow, as the fresh gas is connected directly to the patient connection. It is ideal for spontaneous breathing or manually ventilated infants.

Mapleson F Circuit

• Application: Pediatric anesthesia, controlled or assisted ventilation, suitable for neonates and infants due to its low resistance and lightweight design.
• Components:

• • T-piece: A central piece connecting the fresh gas flow inlet, the breathing tube, and the expiratory limb.
  • Reservoir Bag: An open-ended bag attached to the expiratory limb, allowing manual control of ventilation and visual assessment of breathing.
  • Breathing Tubing: Low-resistance, flexible tubing connecting the T-piece to the patient.

• Gas Flow Requirements: Requires a high fresh gas flow (2-3 times the patient’s minute ventilation) to prevent rebreathing of exhaled gases.
• Operation:

• • Fresh gas flows into the T-piece during inspiration.
  • Expired gases exit through the reservoir bag during expiration.
  • The open-ended bag allows excess gas to escape, reducing pressure build-up.
