The impact of biological sex and stroke volume constituents on heterogeneity in the Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ relationship and skeletal muscle saturation during cycling

Experimental Physiology, EarlyView.
Abstract Interindividual variability in the cardiac output (Q̇$\dot{Q}$) to the rate of oxygen consumption (V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) slope (Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) in healthy males is related to stroke volume (SV); however, the impact of differences in left ventricular (LV) structure and function as well as ...

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

The Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

Valoración hemodinámica del paciente con shock séptico ¿Termodilución o ecocardiografía?

Revista Electrónica de AnestesiaR, 2019
El shock séptico representa una de las principales causas de fracaso circulatorio agudo en las Unidades de Cuidados Intensivos . Tanto las técnicas de monitorización hemodinámica basadas en la termodilución (TPT), como la ecocardiografía (CCE) son ...

The effect of haemodynamic and peripheral vascular variability on cardiac output monitoring: thermodilution and non‐invasive pulse contour cardiac output during cardiothoracic surgery

Anaesthesia, 2018
While haemodynamic variability interferes with the assumption of constant flow underlying thermodilution cardiac output calculation, variability in (peripheral) arterial vascular physiology may affect pulse contour cardiac output methods. We compared non‐

Pulmonary artery catheters or central venous catheters for cardiac surgery: the PUMA Pilot randomised clinical trial

Anaesthesia, Volume 81, Issue 10, Page 1358-1366, October 2026.
Summary Introduction Pulmonary artery catheters are used widely in cardiac surgery despite observed associations with worse outcomes and guidelines that recommend against their routine use. No adequately powered randomised trials are available. Methods The PUMA Pilot was a multicentre, randomised, parallel assignment, open‐label, pilot and feasibility ...

Hemodynamic Analysis of Pediatric Septic Shock and Cardiogenic Shock Using Transpulmonary Thermodilution

BioMed Research International, 2017
Septic shock and cardiogenic shock are the two most common types of shock in children admitted to pediatric intensive care units (PICUs). The aim of the study was to investigate which hemodynamic variables were associated with mortality in children with ...

On the History of Hepatic Vein Catheterization

Liver International, Volume 46, Issue 9, September 2026.
ABSTRACT Hepatic vein catheterization (HVC) in man was first performed 80 years ago in the wake of right‐sided heart catheterization. Several new methods, recognitions and concepts followed, especially the indirect Fick‐method for determination of splanchnic blood flow. Five years passed before pressure measurements were performed and routine HVCs were

The Impact of Cardiac Output Methods on the Classification of Pulmonary Hypertension

Pulmonary Circulation
Cardiac output is essential to calculate pulmonary vascular resistance (PVR) and classify pulmonary hypertension (PH). Recent evidence has shown a lower agreement between thermodilution (COTD) and direct Fick (CODF) methods than historically estimated ...
