Which component of a tracheostomy tube primarily seals the airway to prevent air leaks?

Explanation:
The main concept is sealing the airway with an inflatable cuff. When the cuff around the tracheostomy tube is inflated inside the trachea, it creates a tight seal that prevents air from leaking around the tube during ventilation and helps protect against aspiration of secretions. The other components serve different roles: the obturator guides the tube during insertion, the tie secures the tube around the neck, and the flange helps stabilize and position the tube externally. Keeping appropriate cuff pressure is important to avoid tracheal tissue injury while ensuring an effective seal.
