Respiratory Parameters Using Advanced Airways During In-hospital Cardiac Arrest

Summary

The investigators aim to investigate the real life volumes of air delivered to the lungs when rescuers deliver these breaths by hand as part of resuscitation attempts during cardiac arrest. The study will compare the volumes achieved using different devices which are routinely used to provided an airway during routine cardiac arrest care. Volumes will be measured using a small non intrusive device which sits in the airway circuit and measures flow of air in real time. The patients chosen for this study will be those already recruited to an ongoing trial (AIRWAYS-3) assessing the outcomes for patients suffering in hospital cardiac arrest based on airway device used.

Eligibility

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
