Final answer:
The one principle that is conserved between all continuous monitoring blood culture systems is Microbial Growth.
Step-by-step explanation:
The one principle that is conserved between all continuous monitoring blood culture systems is Microbial Growth. Continuous monitoring blood culture systems are used to detect the presence of microorganisms in the blood, typically bacteria or fungi. These systems provide continuous data on microbial growth, allowing for early detection of bloodstream infections.
