Planning an ambulance around patient care

Patient transport, emergency monitoring and isolation call for different ambulance layouts. The patient-care role determines where the crew needs working space and which medical equipment must fit. In this catalog, Class A, B and C are the names used for the three packages in the comparison. They do not establish equivalence to a destination standard; the purchase specification needs to name the required standard and care role.

Build the power and climate-control requirements around that layout, with an agreed cleaning process. An isolation vehicle needs a negative-pressure system whose specified performance is validated; an ordinary emergency ambulance does not establish that capability. Check destination approval requirements and use the ambulance procurement and acceptance guide to match the equipment and handover records to the agreed specification.
