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 ...

Simplification of continuous intracoronary thermodilution [PDF]

EuroIntervention
Continuous intracoronary thermodilution with saline allows for the accurate measurement of volumetric blood flow (Q) and absolute microvascular resistance (Rμ). However, this requires repositioning of the temperature sensor by the operator to measure the entry temperature of the saline infusate, denoted as Ti.We evaluated whether Ti could be predicted ...

Simultaneous Assessment of Skeletal Muscle Energetics and Blood Flow During Dynamic Exercise by Interleaved 31P‐MRS/1H‐MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 13-26, July 2026.
ABSTRACT Purpose To simultaneously measure skeletal muscle energetics and blood flow (BF) before, during, and after dynamic plantar flexion exercise (PFE). Methods Non‐localized pulse‐acquire phosphorus‐31 magnetic resonance spectroscopy (31P MRS) and phase contrast flow magnetic resonance imaging (1H MRI) using golden‐angle rotated spiral readouts ...

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

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 ...

Transitioning From Oral to Intravenous Treprostinil in Pulmonary Arterial Hypertension: A Case Report

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT The optimal approach to transitioning from oral treprostinil to intravenous treprostinil in pulmonary arterial hypertension (PAH) has been poorly characterized in published literature. We present a case involving a 21‐year‐old male with PAH experiencing worsening symptoms despite treatment with high doses of oral treprostinil (36.75 mg three ...

Comparison of transthoracic electrical bioimpedance cardiac output measurement with thermodilution method in post coronary artery bypass graft patients

Annals of Cardiac Anaesthesia, 2011
Transthoracic electrical bioimpedance (TEB) has been proposed as a non-invasive, continuous, and cost-effective method of cardiac output (CO) measurement. In this prospective, non-randomized, clinical study, we measured CO with NICOMON (Larsen and Toubro
