ClinConnect Summary

This clinical trial is studying a new, simple way to check if the upper part of the airway (the throat and voice box area) is open and working well in patients who have had a tracheostomy—a breathing tube placed through the neck—for a long time. The researchers plan to use a special speaking valve along with a gentle pressure measurement to see if this test can predict how well the airway is functioning without needing more invasive procedures.

People who might join this study are adults who have been off a ventilator (a breathing machine) for more than two days, have stable heart and lung health, no serious infections or organ problems, and whose carbon dioxide levels in the blood are within a safe range. Patients and their families will need to agree to participate by signing a consent form. If you join, you can expect non-invasive testing that involves using the speaking valve and pressure measurements to help doctors understand your airway condition better. This study is not yet recruiting participants, but it aims to make airway checks easier and safer for people with long-term tracheostomies.
