Providers did receive AIR device feedback during newborn mannequin ventilation

Device provides visual feedback related to air leak, obstruction, hyperventilation, hypoventilation, and harsh breaths

Duration of effective bag-mask ventilation by clinician during a 2-minute trial. [This will be a cumulative duration of the two minutes. This is measured internally from the AIR device. "Effective ventilation" is defined as having all three of the following conditions simultaneously: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance >4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance <0.10 mL/cm H2O or resistance >90 cmH2O/L/s). These measurements are determined by sensors in the AIR device for both arms of the study. Their accuracy for manikin use was determined to be 100% in the following trial: Bennett el al. Anesth Analgesia. 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.]

How long it takes for clinician to achieve effective ventilation during 2-minute trial. [This is time from when the mask first touches the face of the manikin until all three icons are green. This is measured by a Research Assistant using a stop-watch. Again, "Effective ventilation" is defined as having all three of the following conditions simultaneously and is indicated to the RA by all three icons on the AIR device turning green: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance >4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance <0.10 mL/cm H2O or resistance >90 cmH2O/L/s). These measurements are determined by sensors in the AIR device for both arms of the study. Their accuracy for manikin use was determined to be 100% in the following trial: Bennett et al. Anesth Analgesia 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.]

Ability of clinician to correctly assess three different manikin airway issues: normal, air leak, or obstruction. [Manikin "conditions" are blinded to the participants and were either normal (as supplied by the manufacturer, had a "leak" insert (introduced compliance >4mL/cm H2O), or had an "obstruction" insert (introduced a reduction in compliance <0.10mL/cm H2O and resistance >90 cm H2O/L/s. As per the parameters in the following paper: Bennett et al. Anesth Analgesia. 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.]
