Hi-Lo Endotracheal Tubes

The Cardinal Health Hi-Lo endotracheal tubes in this collection are the tubes anesthesia providers, emergency clinicians, and critical care teams reach for when securing a definitive airway. Each is a clear, curved PVC tube with a high-volume, low-pressure (Hi-Lo) cuff — the design that gives the line its name. That low-pressure seal is what protects the tracheal wall during prolonged intubation, distributing cuff pressure over a wider mucosal area to reduce the risk of ischemic injury while still maintaining a reliable seal for positive-pressure ventilation.

Every tube here is sterile, single-use, and features a Murphy eye — the side hole near the tip that keeps ventilation flowing if the beveled end becomes occluded against the tracheal wall or by secretions. All are suitable for oral or nasal placement in adult patients, with radiopaque markings and clear walls that let you confirm placement and monitor for condensation.
