Effectiveness of Comprehensive Intervention on Sepsis-Related Organ Failure Assessment (SOFA) Upon the Knowledge and Practice Among Nurses
Abstract: Background: Sepsis is the body's overpowering and potentially fatal response to infection, which can result in tissue damage, organ failure, and death. To put it another way, it is the body's overactive and toxic response to infection. The immune system typically works to fight pathogens to prevent infection (bacteria, viruses, fungi, or parasites). As an infection arises, the immune system will attempt to combat it with the aid of medication …
