Hi-Lo Endotracheal Tubes

Hi-Lo endotracheal tubes from Cardinal Health are built around the high-volume, low-pressure (Hi-Lo) cuff design that has become a clinical standard for intubated patients. The larger cuff surface seals the trachea at lower cuff pressures, which helps distribute pressure across the tracheal wall and reduce the risk of mucosal injury during extended ventilation — a key concern for anesthesia providers and critical care teams managing patients over hours or days.

Every tube in this collection is clear plastic with a curved profile, sterile, and features a Murphy eye to preserve airflow if the beveled tip becomes obstructed. The clear wall allows quick visual confirmation of condensation and secretions. All are suited for adult oral or nasal intubation.

Sizing runs through the range clinicians reach for most. The Shiley Hi-Lo tubes cover 6.5, 7.0, 7.5, and 8.0 mm inner diameters (models 86110–86113), giving intubating teams a predictable set of options for average adult airways. For larger patients, the 8.5 mm Hi-Lo (86114) provides greater flow capacity, while the 7.0 mm Intermediate Hi-Lo tube (86450) offers a mid-range choice within the same trusted cuff platform.

Choosing the right internal diameter is largely about balancing airway resistance against tracheal fit — larger IDs ease ventilation and suctioning, while smaller sizes suit narrower anatomy and reduce trauma on insertion. Stocking a spread of sizes keeps your intubation cart ready for elective and emergent cases alike.
