ENDOTRACHEAL TUBE 9 CUF

An Endotracheal Tube (ETT) size “9 CUF” refers to a large-diameter, cuffed tube (often for adults/larger patients) used for securing airways during ventilation, with “9” indicating its 9.0 mm internal diameter (ID) and “CUF” (or Cuffed) meaning it has an inflatable balloon to seal the trachea, preventing leaks and aspiration, crucial for mechanical ventilation in ORs or ICUs.
