Project Background ● Two Tier 3 (most advanced) hospitals in Honduras (Tegucigalpa & San Pedro Sula) ● Infants and/or mothers travel to closest lower tier hospital, then are transported to Tier 3 location for more intensive care ● No specialized infrastructure exists to transport the infant and/or mother ● Neonates wait for open incubator 4
Project Background 5
Problem Statement: The Problem ● Neonatal Unit ○ Medical unit with the intent to treat premature and critical care infants ● In Honduras there are two hospitals with neonatal intensive care units ○ Hospital Escuela in Tegucigalpa and Mario Catarino Rivas Hospital in San Pedro Sula ● 60% of the nation's infant fatalities occur at these locations ○ 52.2% of this due to infants waiting for incubators ○ Large portion of this wait is the transport from lower tiered hospitals ● There is no designated transportation to get a critically ill infant from a lower tier hospital to either hospital with top tier NICU’s ○ As a result many infants do not survive the trip or make the trip at all 6
Problem Statement: The Solution ● Proposal of a design for an emergency neonatal transport vehicle ○ Transportation from hospital to hospital ● Must be a functional design for Honduras ○ Be within a reasonable budget ■ Cost of building and repairing ○ Parts for repair must be attainable in Honduras ○ Durable enough to keep repair cost low and effectiveness high ○ Easy to operate so as to not rely on a high level of knowledge from operator ● Must be effective in its role ○ Contain all necessary equipment ○ Be capable of powering all necessary systems 7

Use Scenarios A Tier 2 Hospital calls Hospital Escuela with an infant in need of transport for more specialized care... Scenario 1: There is no medical personnel present in vehicle Scenario 2: The driver is the only medical professional present Scenario 3: The driver and an additional EMT are both present in the vehicle Scenario 4: The driver is not a trained medical professional, but an EMT is present in the back 10

Current Gaps ● Unclear customer requirements (need medical input) ● Undefined engineering requirements (need customer clarification and additional research to quantify requirements) ● No budget requirements or limitations given past “inexpensive” ● Certain specifications need to be determined in regards to available space and technology 20
