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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

After major surgery, patients are often asked to do deep-breathing exercises using a plastic device called an incentive spirometer to keep oxygen levels up. This trial tests whether automatic reminders — a dim light and a soft buzz every 20 minutes while awake — encourage patients to do these exercises more often. The study includes adults having non-cardiac surgery who are at higher risk for breathing problems. The goal is to see if simple, low-cost reminders can make a real difference in recovery.

What this could mean

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

Active substance
automatic reminders (dim light and soft buzz) every 20 minutes during waking hours
What this could lead to
If it works, this simple reminder system could help prevent low oxygen and other breathing problems after major surgery.
What could go wrong
The trial is small and early-stage, so results may not apply to all patients. The reminders might be ignored or become annoying.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 88 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Nov 2026

An estimate. Start dates often move.

Expected to finish

Jan 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * ≥18 years * Planned non-cardiac surgery under general anesthesia with at least one night of hospitalization expected * Preoperative ARISCAT risk score ≥26 * Signed informed consent Exclusion Criteria: * Inability to perform IS due to refusal, cognitive impairment, neuromuscular weakness, anatomical, or any other reasons (e.g., tracheotomy, oral surgery, unable to hold incentive spirometer) * Have a severe hearing or visual acuity impairment that prevents them from hearing or seeing the audible and visual IS reminders * Are part of a vulnerable population (minors, pregnant, prisoners) * Lack of informed consent
