Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Transpulmonary thermodilution: advantages and limits

Critical Care, 2017
Background For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination.

Comparison of two cardiac output monitors, qCO and LiDCO, during general anesthesia [PDF]

, 2016
Background: Optimization of cardiac output (CO) has been evidenced to reduce postoperative complications and to expedite the recovery. Likewise, CO and other dynamic cardiac parameters can describe the systemic blood flow and tissue oxygenation state and

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 ...

Derivation of Stroke Volume from Pulmonary Artery Pressures

Cardiology and Therapy
Introduction Intermittent cardiac output (CO) studies using thermodilution are considered the gold standard. We have developed a stroke volume (SV) calculator from pulmonary pulse pressure (PP) to allow continuous monitoring of SV and CO from PP. Methods

Hemodynamic profiling by critical care echocardiography could be more accurate than invasive techniques and help identify targets for treatment

Scientific Reports, 2022
In this prospective observational study, non-invasive critical care echocardiography (CCE) was used to obtain quantitative hemodynamic parameters in 107 intensive care unit (ICU) patients; the parameters were then visualized in a novel web graph approach

Less invasive methods of advanced hemodynamic monitoring: principles, devices, and their role in the perioperative hemodynamic optimization. [PDF]

, 2013
The monitoring of the cardiac output (CO) and other hemodynamic parameters, traditionally performed with the thermodilution method via a pulmonary artery catheter (PAC), is now increasingly done with the aid of less invasive and much easier to use ...

An experimental medicine protocol for exploring the haemodynamic effects of dual agonism at the glucagon‐like peptide‐1 and glucagon receptor in healthy subjects

British Journal of Clinical Pharmacology, Volume 92, Issue 2, Page 579-588, February 2026.
Aims Glucagon‐like peptide‐1 (GLP‐1) and glucagon dual receptor agonists are in clinical development for a range of metabolic conditions, including type 2 diabetes and obesity. The cardiovascular actions at these receptors are well studied, but less is known about their combination.

Knowledge Gaps and Controversies on Cardiopulmonary Exercise Testing in the Assessment of Pulmonary Vascular Disease: An Official Statement of the Pulmonary Vascular Research Institute Exercise and Right Ventricular Function Task Force

Pulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Exercise testing has long been essential for evaluating diagnosis, prognosis, and functional status in pulmonary hypertension (PH). Recent advances have clarified its role in defining reference values and prognostic markers. Nonetheless, substantial knowledge gaps persist regarding the implementation of invasive cardiopulmonary exercise ...
