How speaking valves affect your vital signs
Part of Lungs & breathing clinical trials.
This study looks at how using a speaking valve (a one-way valve that lets you breathe in through the trach but out through your mouth) affects your heart rate, breathing, and other vital signs. It uses small wearable monitors to track these changes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must not be on a breathing machine (ventilator).
- You need to be able to tolerate having the balloon (cuff) around your trach tube deflated.
- Your upper airway should be open enough to breathe around the trach tube.
- You must be medically stable, without organ failure or uncontrolled infections or sepsis.
- Your carbon dioxide (CO2) level in the blood should be less than 60 mmHg.

This study looks at how your breathing changes after removing a tracheostomy tube, using a valve and simple breathing tests. It may help doctors better plan your recovery.
This study compares two ways to prepare patients with a tracheostomy (a breathing tube in the neck) for having it removed. It tests whether a standard method or using a special valve (incremental dead space) works better for safe removal.
This study uses a small wearable monitor to track your body's signals, like breathing and heart rate, to help doctors predict when it's safe to remove your tracheostomy tube. The goal is to make the decision to remove the tube more reliable and safer for you.
This study watches people when their tracheostomy tube is removed to see how it affects their body, like breathing and heart rate. You'll wear small sensors on your skin that track your health for a few days, and the information may help doctors know when it's safe to remove the tube.
This trial tests whether using a speaking valve (a small one-way valve that lets you breathe and speak) helps people with a tracheostomy and long-term consciousness problems safely remove their tracheostomy tube, compared to a standard capping method.
This study tests a new way to help people with long-lasting disorders of consciousness get their tracheostomy tube removed using a voice valve. If you qualify, this might help improve recovery and communication.
