Asphyxia Neonatorum, Birth Asphyxia, Perinatal Asphyxia
Conditions
Brief summary
Augmented Infant Resuscitator (AIR) is an inexpensive add-on, compatible with nearly every existing bag-valve mask and many types of ventilation equipment. AIR monitors ventilation quality and provides real-time objective feedback and actionable cues to clinicians to both shorten training times and improve resuscitation quality, adoption, retention, and confidence.
Detailed description
Longitudinal, randomized control trial that examined the effectiveness of AIR among 270 participants, with 1,080 recorded ventilation scenarios, and across 20 sites in Uganda and the U.S. Birth attendants - including a mix of midwives, nurses, respiratory therapists, pediatricians, and neonatologists - with recent HBB and/or NRP training were recruited to participate in this randomized control trial. Participants ventilated training mannequins for a fixed duration of time. Participants were randomized to receive visual feedback from AIR (intervention) or have the AIR feedback covered (control). They were then requested to administer effective ventilation and verbally assess the mannequin condition. All mannequins appeared to be identical, but each session's mannequin was randomly selected with an upper airway that was normal, partially leaking, or partially obstructed.
Interventions
Device provides visual feedback related to air leak, obstruction, hyperventilation, hypoventilation, and harsh breaths
DEVICEAIR device without feedback
Device provides no visual feedback to clinician but records data on ventilation effectiveness

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effective bag-mask ventilation | 2 minutes | Duration of effective bag-mask ventilation by clinician during a 2-minute trial. \[This will be a cumulative duration of the two minutes. This is measured internally from the AIR device. Effective ventilation is defined as having all three of the following conditions simultaneously: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance \>4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance \<0.10 mL/cm H2O or resistance \>90 cmH2O/L/s). These measurements are determined by sensors in the AIR device for both arms of the study. Their accuracy for manikin use was determined to be 100% in the following trial: Bennett el al. Anesth Analgesia. 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.\] |
| Time to effective bag-mask ventilation | 2 minutes | How long it takes for clinician to achieve effective ventilation during 2-minute trial. \[This is time from when the mask first touches the face of the manikin until all three icons are green. This is measured by a Research Assistant using a stop-watch. Again, Effective ventilation is defined as having all three of the following conditions simultaneously and is indicated to the RA by all three icons on the AIR device turning green: (1) Correct rate (30-60 breaths per minute); (2) Absence of significant leak (compliance \>4.0mL/cm H2O); and (3) Absence of a significant airway blockage (defined as compliance \<0.10 mL/cm H2O or resistance \>90 cmH2O/L/s). These measurements are determined by sensors in the AIR device for both arms of the study. Their accuracy for manikin use was determined to be 100% in the following trial: Bennett et al. Anesth Analgesia 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.\] |
| Clinician's correct assessment of mannequin airway issues | 2 minutes | Ability of clinician to correctly assess three different manikin airway issues: normal, air leak, or obstruction. \[Manikin conditions are blinded to the participants and were either normal (as supplied by the manufacturer, had a leak insert (introduced compliance \>4mL/cm H2O), or had an obstruction insert (introduced a reduction in compliance \<0.10mL/cm H2O and resistance \>90 cm H2O/L/s. As per the parameters in the following paper: Bennett et al. Anesth Analgesia. 2018 Mar;126(3):947-955. doi: 10.1213/ANE.0000000000002432.\] |
