Hemoglobin Mass and Blood Volume in Patients With Altitude-Related Polycythemia

Frontiers in Physiology, 2022
Patients with chronic mountain sickness (CMS) have a high hemoglobin concentration [Hb] due to increased hemoglobin mass (Hbmass) and possibly reduced plasma volume (PV). The values of Hbmass, PV and blood volume (BV) have been described differently, and

Estimated plasma volume status can help identify patients with sepsis at risk of death within 30 days in the emergency department

Emergency Care Journal, 2023
For patients with sepsis in the Emergency Department (ED), early risk stratification is important to improve prognosis. The study aimed to evaluate the predictive role of estimated plasma volume (ePVS) on admission to the ED.

Dose of Bicarbonate to Maintain Plasma pH During Maximal Ergometer Rowing and Consequence for Plasma Volume

Frontiers in Physiology, 2022
Rowing performance may be enhanced by attenuated metabolic acidosis following bicarbonate (BIC) supplementation. This study evaluated the dose of BIC needed to eliminate the decrease in plasma pH during maximal ergometer rowing and assessed the ...

Exercise Heat Acclimation With Dehydration Does Not Affect Vascular and Cardiac Volumes or Systemic Hemodynamics During Endurance Exercise

Frontiers in Physiology, 2021
Permissive dehydration during exercise heat acclimation (HA) may enhance hematological and cardiovascular adaptations and thus acute responses to prolonged exercise. However, the independent role of permissive dehydration on vascular and cardiac volumes,

Low Plasma Volume and Increased Pressure Load Relate to Concentric Left Ventricular Remodeling After Preeclampsia: A Longitudinal Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background During uncomplicated pregnancy, left ventricular remodeling occurs in an eccentric way. In contrast, during preeclamptic gestation, the left ventricle hypertrophies concentrically, concurrent with loss in circulatory volume and increased blood

Relationship between Blood Volume, Blood Lactate Quantity, and Lactate Concentrations during Exercise

Metabolites, 2023
We wanted to determine the influence of total blood volume (BV) and blood lactate quantity on lactate concentrations during incremental exercise. Twenty-six healthy, nonsmoking, heterogeneously trained females (27.5 ± 5.9 ys) performed an incremental ...

Effects of the two consecutive anaerobic exercise sessions on leukocyte subsets distribution, blood lactate level and anaerobic power in female athletes with controlling the confounding effect from plasma shift [PDF]

مجله پزشکی دانشگاه علوم پزشکی تبریز, 2020
Background: The majority of existing data concerning the leukocyte subsets distribution after daily consecutive exercise sessions are controversial because of the confounding effect of plasma shift into active muscles.

The Influence of Training Load on Hematological Athlete Biological Passport Variables in Elite Cyclists

Frontiers in Sports and Active Living, 2021
The hematological module of the Athlete Biological Passport (ABP) is used in elite sport for antidoping purposes. Its aim is to better target athletes for testing and to indirectly detect blood doping.
