Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study explores whether a simple breathing test done before surgery can help predict when a patient's oxygen levels might drop dangerously low during lung surgery. Researchers will measure how air moves through the lungs while patients breathe normally, then track oxygen levels during the operation. The goal is to find a way to identify at-risk patients ahead of time, so doctors can take steps to keep them safe. About 44 adults undergoing lung surgery for cancer will take part.
