in Honduras (Tegucigalpa & San Pedro Sula)
closest lower tier hospital, then are transported to Tier 3 location for more intensive care
transport the infant and/or mother
In Honduras, there is currently a lack of quick, safe, and reliable transportation between hospitals for infants with serious medical conditions.
○ Transportation between hospitals
○ Be within a reasonable budget ■ Consider costs of build, maintenance, and repair ○ Parts for repair must be readily accessible in Honduras ○ Durable - keep repair cost low and effectiveness high ○ Easy to operate
○ Contain all necessary equipment ○ Provide power for all necessary systems
Limitations
Scenario
1. Hospital calls for ambulance 2. Ambulance makes 4 hour drive to hospital 3. Picks up multiple infants and family members 4. Transports back to Hospital Escuela
a. No in-transport care b. Driver has no medical training
5. Ambulance arrives and infants are removed for care Servicing 2 hospitals (Comayagua and La Esperanza)
Extended Truck Chassis with Box
space for monitor ○ Shows driver infant conditions ○ Removes distractions
○ Removes access to equipment
infants (more area to work)
personnel
Many Things Have Changed...
1. Comayagua calls Hospital Escuela with critical care infant(s) 2. Doctors at Escuela consult on necessary care 3. Vehicle is loaded with...
a. Required number of incubators (flexible) b. Driver c. Medical personnel
4. Vehicle travels to Comayagua 1 hour away 5. Infant is loaded into Incubator 6. Vehicle returns to Escuela The idea is to take ONLY critical care infants, as Comayagua needs to learn how to handle more complicated cases
