What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a small motion sensor taped to the chest can measure the volume of air a person inhales, similar to a standard incentive spirometer. Thirty healthy adults took 18 different breaths while wearing the sensor and breathing through a spirometer. The goal was to see if the sensor's data could be used to develop a software algorithm that estimates breath volume from chest movement alone.

What this could mean

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

Active substance
Motion sensor (device)
What this could lead to
If successful, this could lead to a simple, wearable way to monitor breathing after surgery, helping prevent lung complications.
What could go wrong
This is a very small, early feasibility study with only 30 healthy adults. It does not test whether the sensor actually prevents complications, only whether it can measure breath volume accurately.
