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.

Primary Outcome Measures: Tidal Volume, The mean tidal volume achieved during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.
Secondary Outcome Measures: Mean leak, The mean volume of leak recorded during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.|inspiratory time, The mean inspiratory time during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.|Expiratory time, The mean expiratory time during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.
Other Outcome Measures: Respiratory rate, Mean Respiratory rate delivered during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.|Smallest tidal volume, The smallest tidal volume delivered during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.|largest tidal volume, The largest tidal volume delivered during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.|duration of intervention, The time for which the airway device was used during cardiac arrest treatment, assessed from the initiation of advanced airway management to the cessation of the resuscitation treatment (Return of spontaneous circulation or death). Through completion of data collection, ranging between minutes to 1 hour.
