Tiny device reveals Real-Life breath volumes in cardiac arrest
NCT ID NCT06580652
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.

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
