Summary

This study will observe 300 adults scheduled for a lung biopsy (EBUS-TBNA) to see if the size of their windpipe, measured by ultrasound before the procedure, can predict dangerous drops in oxygen levels. The procedure is done under sedation, and low oxygen is a known risk. The goal is to find a simple way to identify high-risk patients and improve safety.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could help doctors identify patients at higher risk for low oxygen during EBUS-TBNA, allowing them to take extra precautions.
What could go wrong: This is an observational study, not a treatment trial. It only looks for a link between tracheal size and oxygen drops; it won't test any new therapy or device.
