Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Cerebral and peripheral haemodynamics at rest and in response to orthostasis during 3 days of simulated heatwave

Experimental Physiology, EarlyView.
Abstract Acute heat stress reduces cerebral haemodynamics and orthostatic tolerance. However, the haemodynamic response to orthostasis during prolonged heat stress typical of heatwaves is unknown. We hypothesised that thermoregulatory‐induced elevations in peripheral haemodynamics during 3 days of simulated heatwave would exacerbate orthostatic‐induced

Heart-lung interactions during positive-pressure ventilation

, 1994
Artificial ventilation using intermittent positive airway pressure is the mainstay support of patients in respiratory failure. By maintaining alveolar ventilation and alveolar stability, positive airway pressure can sustain respiratory gas exchange ...

Pressure‐dependent coupling between arterial pressure and intercostal muscle blood‐flow index during acute hypotension in humans

Experimental Physiology, EarlyView.
Abstract Regulation of respiratory muscle blood flow during acute systemic hypotension remains poorly understood in humans because continuous assessment of microvascular perfusion during rapid haemodynamic transients has been technically challenging. Using diffuse correlation spectroscopy, we investigated second‐by‐second coupling between mean arterial

Physiological and autonomic responses to intermittent low‐lung‐volume apnoea and pain sensitivity: A randomized controlled pilot trial

Experimental Physiology, EarlyView.
Abstract Intermittent apnoeas may induce hypoalgesia; however, the effects of low‐lung‐volume static apnoea have not been investigated. Eighty healthy participants were randomized to an apnoea group (AG) or a control group (CG). The AG performed a 6‐min protocol of intermittent static apnoea at low lung volume (passive exhalation), whereas the CG ...
