What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused

Summary

This study tests a special airway device (McMurray Enhanced Airway) to see if it helps patients breathe better during a heart ultrasound (TEE) while sedated with propofol. About 50 adults having an elective TEE will be enrolled. The goal is to reduce the chance of low oxygen levels compared to using a standard nasal cannula.

What this could mean

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

Active substance
McMurray Enhanced Airway (a flexible plastic tube placed in the throat to keep the airway open)
What this could lead to
If it works, this could give doctors a better way to keep patients breathing safely during procedures like TEE under sedation.
What could go wrong
This is a small early study with only 50 people, so results may not apply to everyone. The device might not work better than standard care.
