Covidien 8DFEN Shiley Tracheostomy Tube Cuffed with Disposable Inner Cannula

Covidien 8DFEN Shiley Tracheostomy Tube Cuffed with Disposable Inner Cannula

The Shiley 8DFEN is a substantial adult‑sized tracheostomy tube designed for patients who need a secure airway with enhanced airflow control and the ability to speak or breathe through the upper airway when conditions allow. The “fenestrated” outer cannula has openings (fenestrations) that permit air to pass up through the larynx and vocal cords if the inner cannula is bypassed or removed and the cuff is deflated. The cuffed design allows for a sealed airway when positive pressure ventilation is needed or when protection from aspiration is required, reducing leakage and improving ventilatory efficiency. With an inner diameter of 7.6 mm and an outer diameter of 12.2 mm, and a length of about 79 mm, this tube is suitable for adult anatomies with larger airway demands. The cuff’s resting outer diameter (when inflated) is 27 mm, which provides a good seal without causing undue pressure when managed properly.

Additional product details

• Using a disposable inner cannula offers certain conveniences and advantages. The disposable cannula uses a snap‑lock 15 mm connector, simplifying removal.
• Clinically, the 8DFEN tube is particularly useful for patients who are stable enough to benefit from speech and upper airway airflow, but who also need the security of a cuff for periods of ventilation or protection. For example, a patient who is being weaned from ventilator support might have the cuff deflated and use the fenestration to try to phonate or breathe through mouth/nose, while still having the cuff available for times when seal is needed. The size (ID/OD/length) must be well matched to the patient’s anatomy to avoid problems: too large a tube can damage the tracheal mucosa or risk pressure injury; too small can increase work of breathing, permit too much leak, or be prone to obstruction. Regular assessment of cuff pressure, inner cannula patency, hygiene, stoma condition, and patient comfort are essential to avoid complications such as granulation tissue, mucosal injury, or decannulation.
