Sepsis 6 was a group of sepsis interventions pre-dating the sepsis bundles. The Sepsis 6 included all of the elements of the 3-hour bundle, including drawing a lactic acid, blood cultures, administering IV fluids and antibiotics. The other two elements, not specifically noted in the 3- or 6-hour bundle includes giving supplementary oxygen and commencing accurate urine output measurement. The success of the Sepsis 6 influenced development of our current sepsis bundles.
