Nurses’ and patients’ experiences and preferences of the Ankle-Brachial Pressure Index and Multi-site Photoplethysmography for the diagnosis of peripheral arterial disease: A qualitative study [PDF]
, 2019 Peripheral arterial disease is a global health problem, affecting around 20% of people aged over 60 years. Whilst ankle-brachial pressure index (ABPI) is regularly used for diagnosis, it has a number of limitations, which have presented a need for ...

Photoplethysmography Revisited: From Contact to Noncontact, From Point to Imaging [PDF]
IEEE Transactions on Biomedical Engineering, 2016 Photoplethysmography (PPG) is a noninvasive optical technique for detecting microvascular blood volume changes in tissues. Its ease of use, low cost and convenience make it an attractive area of research in the biomedical and clinical communities. Nevertheless, its single spot monitoring and the need to apply a PPG sensor directly to the skin limit its

Equine Veterinary Journal, EarlyView.Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Cerebral haemodynamic responses to inspiratory muscle work
Experimental Physiology, EarlyView.Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study
Experimental Physiology, EarlyView.Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.
