Modified Endotracheal Balloon Dilator to Improve Patient Oxygenation and Allow Ventilation During Airway Procedures

Modified Endotracheal Balloon Dilator to Improve Patient Oxygenation and Allow Ventilation During Airway Procedures

The purpose of the study is to prospectively assess the use of a modified tracheal balloon dilator that allows gas flow (oxygenation and ventilation) through the device while inflated during dilatation.

The primary aim is to determine the incidence of, and time to, arterial desaturation (defined as peripheral plethysmography below 90%). Secondary aims include quantitative and qualitative (waveform) end-tidal capnography levels throughout the procedure, quantitative assessment of dilatation, and incidence of adverse events.

Inclusion Criteria:

• Age >18 years
• Symptoms of tracheal or laryngeal stenosis or airway narrowing
• Endoscopic evidence of subglottic or tracheal stenosis
• Able to provide informed consent

Exclusion Criteria:

• Refractory stenosis not amenable to balloon dilatation
• Contraindication to balloon dilatation
• Lack of informed consent
