Project Background

Problem Statement: The Problem
○ Medical unit with the intent to treat premature and critical care infants
○ Hospital Escuela in Tegucigalpa and Mario Catarino Rivas Hospital in San Pedro Sula
○ 52.2% of this due to infants waiting for incubators ○ Large portion of this wait is the transport from lower tiered hospitals
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
○ Transportation from hospital to hospital
○ 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
○ Contain all necessary equipment ○ Be capable of powering all necessary systems

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
