Why the study?
Does external monitoring provide a reproducible measurement of central blood volume compared to interrupted arterial samples in normal subjects?
Does external monitoring provide a reproducible measurement of central blood volume compared to interrupted arterial samples in normal subjects?
External monitoring with a dual-counter setup offers a reproducible technique for measuring the amount of blood in the heart and lungs, though it yields lower volumes than arterial sampling.
No takes yet. Share an insight, caveat, or question.
External monitoring yields lower central blood volume estimates than arterial sampling; leaves open reproducibility as a noninvasive technique.
