Enabling safer bronchoscopy through direct tracheal oxygen delivery.
A bronchoscopy-compatible device that helps maintain oxygenation by delivering oxygen during the procedure, beyond the anatomical bottleneck.
Engineered in SwitzerlandSedation lowers blood oxygen during bronchoscopy.
Flexible bronchoscopy is a key minimal invasive procedure in pulmonary medicine with an expected count of 6 million annual procedures and projected further increase [1]. Due to sedation effects, partial airway blocking by the endoscope and underlying respiratory diseases, blood oxygen desaturations are one of the most relevant complications with a frequency near to 60% [2].
The current management encompasses a wide range of measures from low-flow nasal oxygen plugs up to endotracheal intubation which gradually increase the invasiveness of the procedure [3].

Oxygen delivered beyond the bottleneck.
Lungstream is developing a bronchoscopy-compatible oxygen delivery approach designed to help maintain oxygenation during airway procedures by delivering oxygen beyond the anatomical bottleneck. It is a sterile single-use device that works with the oxygen supply and the bronchoscope already present in every endoscopy suite, so no capital equipment is required.
Subglottic Oxygen
Supplemental oxygen is delivered past the narrowing that limits conventional upper-airway supply.
Ease of Use
Designed to integrate into routine bronchoscopy with no new capital equipment and no retraining.
Single-Use Device
Removes reprocessing and cross-contamination concerns associated with reusable accessories.
