1 NeO 2 Inspire This project and the respective study were supported by Laerdal Global Health and Jhpiego, both Johns Hopkins University affiliates. However, there are no conflicts of interest as the project is part of the Johns Hopkins’s Center for Bioengineering Innovation and Design (CBID) program.

3 Clinical Definition “Birth asphyxia [is] defined as the failure to establish breathing at birth.” - WHO Bulletin on Birth Asphyxia Approximately 1 million deaths annually due to birth asphyxia 99% deaths occur in low-resource areas

4 NeO 2 Inspire’s Mission To improve the outcome of neonatal & infant resuscitation in developing countries by providing a simple and cost-effective technology to assist with healthcare worker performance.

5 Current Standard of Care Performed by skilled birth attendants (SBAs)

6 Current Standard of Care Watch chest rise Assess tone and color 40 breaths/min Place mask properly Apply pressure Assess air leak Open airway - Warm and dry - Stimulate - Suction - Check heart rate - Monitor the Golden Minute Ventilation Procedure

7 Current Errors in Workflow Incorrect placement of towel as shoulder raise to open airway Mask seal not established properly Failure to reroll the towel for patent airway due to lack of feedback

8 Clinical Problem Insufficient training Lack of operator feedback Complexity of procedure In the hands of SBAs, failure to open the airway is documented as one of the main causes for failed resuscitation.

9 Our proposed device Our Proposed Solution GoalsConstraints Create patent airway Operable by one person Reduce time spent on opening the airway Able to withstand current standard of disinfection procedure Less than $5 (affordable) Lightweight, so easily portable in purse or bag

10 Airway Manipulation Flexion (Under-extension) Hyper-extension Open Airway

11 Head-Tilt Angle Study Flexion (Under-extension) Hyper-extension Performed retrospective MRI study to validate and define the head-tilt angle required for airway patency in neonates and infants (0-12 months of age). Open Airway No previous data to define angle for these positions.

12 Head-Tilt Angle Study angle Head-tilt angle was measured as the angle between occipito-ophisthion line and ophisthion-C7 spinous process line. Three measures were used to quantify airway patency: 1)Antero-posterior (AP) diameter of the airway at the level of palate 2)Antero-posterior (AP) diameter of the airway at the tongue level 3)Lateral diameter of the airway at tongue level

13 Findings from Head-Tilt Study 66 neonates and 17 infants: Closed airway can be due to either flexion or hyper-extension Angle for airway patency is similar for neonates and infants Validated that device can pertain to children 0-12 months No correlation between mean head-tilt angle and either gestational age or weight of the child Validated that device can pertain to all children 0-12 months regardless of prematurity and weight Open Airway: ± 11.18* *Associated with open airway in spontaneously breathing, sedated neonates and infants Flexion Closed Airway: ± 7.32 Hyper-Extended Closed Airway: ± 8.31

14 Airway Mat Hospitals / Health Centers Box Mat Home Births Our Solution Our proposed solution attempts to address points of difficulty in the neonatal resuscitation protocol.

15 Airway Mat Setting: Primary and Secondary Hospital Settings, Community Health Centers Box Mat Cost: $1.71 Angled at degrees to ensure airway patency Applicable for both neonates and infants (0-12 months of age) Reduces required training Smooth addition to current workflow

16 Airway Mat Setting: Home Births, Community Center Clinics Box Mat Cost: $2.40 Same features as airway mat “Box” aspect allows for easy portability Enough storage room inside box for resuscitation tools (suction penguin, heating pads, BVM)

17 Develop Manufacturing Protocol IRB-approved human study to validate usage of device on neonates and infants. Future Work IRB-approved field study to validate clinical application of device in community centers and hospitals in developing countries.
