NCT ID NCT06580652

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study measures how much air actually reaches the lungs when rescuers give breaths by hand during cardiac arrest. It compares two common airway devices—tracheal tubes and laryngeal mask airways—using a small flow sensor. The 30 participants are already part of a larger trial (AIRWAYS-3). The goal is to understand real-world performance, not to test a new treatment.

What this could mean

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

What this could lead to
If successful, this could help improve resuscitation techniques by showing which airway device delivers more effective breaths during cardiac arrest.
What could go wrong
This is a small observational study (30 participants) nested within a larger trial, so results may not apply broadly. It measures volumes but does not test patient outcomes directly.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * As per AIRWAYS-3 trial: * In-hospital cardiac arrest, attended by the hospital cardiac arrest team in response to a cardiac arrest call (2222 or equivalent), and when a clinician permitted to undertake both tracheal intubation and supraglottic airway placement (so that either intervention can be delivered) is present * Undergoing resuscitation and requiring advanced airway management in the opinion of the trained clinician responsible for randomisation Exclusion Criteria: * As per AIRWAYS-3 trial * Patients who have a cardiac arrest outside hospital and who are transported to the hospital in ongoing cardiac arrest * People who are not a hospital inpatient (e.g. visitor, relative, staff or outpatient) * Patients who are already tracheally intubated at the time of eligibility assessment * Patients known to be pregnant * Patients with a functioning tracheostomy
