Complex Operating Rooms: Procedures involving head/neck manipulation (maxillofacial surgery, cervical spine cases) or difficult intubation (obese patients, trauma).
Intensive Care Units: Prolonged mechanical ventilation for critically ill patients (where tube patency is vital for sustained respiratory support).
Emergency Departments: High-acuity cases (facial trauma, airway edema) with anticipated difficult airway access.
Pediatric Critical Care: Size options (3.0mm–6.0mm ID) for pediatric patients with narrow or anatomically challenging airways.
