This Hewlett Packard 43120A monitor defribulator electro cardiograph equipment was trialled around 1981/1982 to Gren Sylvester at the Ambulance Officer Training Centre. Having proved successful, it was introduced to non-MICA (Mobile Intensive Care Ambulance) ambulances in Victoria. It was used successfully for at least 15 years and was noted for its reliability and also for its ability to keep working after being dropped. It was later replaced by lighter equipment.
