Plasma volume variation across the menstrual cycle among healthy women of reproductive age: A prospective cohort study

Physiological Reports, 2020
Increases in reproductive hormones like estrogen, play an important role in the remarkable increases in plasma volume observed in pregnancy. Accurate estimates of plasma volume expansion during pregnancy depend on correctly timing and measuring plasma ...

Validation of the Accuracy of Automatic Measurement of Blood Volume in Culture Bottles for Blood Culture

Diagnostics, 2023
Several manufacturers have developed systems that automatically measure the amount of blood in culture bottles. We compared the volumes measured automatically by the Virtuo instrument (bioMérieux, France) (height-based volumes) and those calculated by ...

Educational Intervention to Improve Blood Culture Indicators in a Secondary-Care Hospital

Annals of Clinical Microbiology, 2021
배경: 혈액배양은 패혈증을 진단하는데 필수적인 검사이다. 혈액배양 시 충분한 양의 혈액 채취가 중요하며, 질 향상을 위해서는 주기적으로 채혈량 모니터링과 피드백이 필요하다.방법: 2차 의료기관에서 혈액배양 시 고려해야 할 점에 대해서 채혈전담자를 대상으로 교육을 시행하였다.

Postural Hyperventilation as a Cause of Postural Tachycardia Syndrome: Increased Systemic Vascular Resistance and Decreased Cardiac Output When Upright in All Postural Tachycardia Syndrome Variants

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Postural tachycardia syndrome (POTS) is a heterogeneous condition. We stratified patients previously evaluated for POTS on the basis of supine resting cardiac output (CO) or with the complaint of platypnea or “shortness of breath” during ...

Why do SGLT2 inhibitors reduce heart failure hospitalization? A differential volume regulation hypothesis [PDF]

, 2017
The effect of a sodium glucose cotransporter 2 inhibitor (SGLT2i) in reducing heart failure hospitalization in the EMPA-REG OUTCOMES trial has raised the possibility of using these agents to treat established heart failure.

Effects of stimulation conditions and subcutaneous tissue properties on acupressure-induced changes in blood circulation of human tendons

Journal of Physical Fitness and Sports Medicine, 2023
The purpose of this study was to investigate the effects of stimulation conditions (pressing force and frequency) and subcutaneous tissue properties (thickness and hardness) on the changes in tendon blood circulation caused by acupressure.
