摘要
Techniques and apparatuses for determining an estimated cardiac output for a patient during dialysis treatment are described. In one embodiment, for example, an apparatus may include a memory and logic coupled to the memory. The logic may be configured to determine an upper body oxygen consumption for a patient, determine, during a dialysis process: a hemoglobin concentration and a venous oxygen saturation measured via an optical blood monitor operably coupled to an extracorporeal circuit of a dialysis system performing the dialysis process,; an arterial oxygen saturation measured via a pulse oximeter operably coupled to the extracorporeal circuit; an arterial-venous oxygen content difference based on the arterial oxygen saturation and the venous oxygen saturation; and an upper body blood flow (UBBF) as (upper body oxygen consumption)/(arterial-venous oxygen content difference), and determine a treatment recommendation based on the upper body blood flow. Other embodiments are described.
