Comparison of Blood Culture Parameters between 2 and 10 mL Aerobic Bottles from Patients with Sepsis

Annals of Clinical Microbiology, 2021
Background: Blood volume is the most important parameter for an optimal blood culture; however, the effect of blood volume on blood culture is not clearly understood from patients with sepsis. Methods: Blood cultures were obtained from 1,049 patients (≥

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 ...

Microvascular Dynamics and Hemodialysis Response of Patients With End-Stage Renal Disease

Frontiers in Bioengineering and Biotechnology, 2022
In our previous analysis of three sets of hemodialysis studies, we found that patients possessing higher hematocrit have a higher filtration coefficient KSo and more fluid being restituted from the tissue.

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 ...

Differences in Cardiac Output and Aerobic Capacity Between Sexes Are Explained by Blood Volume and Oxygen Carrying Capacity

Frontiers in Physiology, 2022
Whether average sex differences in cardiorespiratory fitness can be mainly explained by blood inequalities in the healthy circulatory system remains unresolved.

Estimated central blood volume in cirrhosis [PDF]

, 1992
The estimated central blood volume (i.e., blood volume in the heart cavities, lungs and central arterial tree) was determined by multiplying cardiac output by circulatory mean transit time in 19 patients with cirrhosis and compared with sympathetic ...

Shining new light on mammalian diving physiology using wearable near-infrared spectroscopy [PDF]

, 2019
Investigation of marine mammal dive-by-dive blood distribution and oxygenation has been limited by a lack of non-invasive technology for use in freely diving animals.

Altered hippocampal function in major depression despite intact structure and resting perfusion [PDF]

, 2016
Background: Hippocampal volume reductions in major depression have been frequently reported. However, evidence for functional abnormalities in the same region in depression has been less clear.

Neuronal and hormonal perturbations in postural tachycardia syndrome

Frontiers in Physiology, 2014
The Postural Tachycardia Syndrome (POTS) is the most common disorder seen in autonomic clinics. Cardinal hemodynamic feature of this chronic and debilitating disorder of orthostatic tolerance is an exaggerated orthostatic tachycardia (≥30 bpm increase in
