Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

On‐feet isometric bracing maintains cerebral arterial blood velocity during lower body negative pressure via preload augmentation

Experimental Physiology, EarlyView.
Abstract Orthostatic stress reduces venous return and stroke volume (SV), risking cerebral hypoperfusion despite autonomic compensation. Although lower‐limb counterpressure manoeuvres improve cerebral perfusion in upright posture, their effects on cerebral blood velocity (CBV) during lower‐body negative pressure (LBNP) and the associated mechanisms are

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.
