The effect of patient positions on perfusion index [PDF]

BMC Anesthesiology, 2018
Background The optimal position for surgery is one in which the patient is provided the best possible surgical intervention and put at minimum risk. Different surgical positions may cause changes in tissue perfusion.

In Patients With Hypertension, the Cortical Perfusion Index Measured by Contrast Enhanced Ultrasound Reveals a Sexual Dimorphism [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Arterial hypertension is characterized by microvasculature changes and reduced tissue perfusion. It is unknown whether a sexual dimorphism of renal microcirculation is present in patients with arterial hypertension.

Effects of different approaches of infraclavicular brachial plexus block on perfusion index and tissue perfusion. [PDF]

Ann Med
Although both the lateral sagittal and costoclavicular approaches are applied at the cord level in the infraclavicular region, there is a major difference between the distributions of the two approaches. We aimed to investigate the effects of this different distribution on tissue perfusion and oxygenation.Sixty patients undergoing elective elbow ...

Evaluation of feline renal perfusion with contrast-enhanced ultrasonography and scintigraphy [PDF]

, 2016
Contrast-enhanced ultrasound (CEUS) is an emerging technique to evaluate tissue perfusion. Promising results have been obtained in the evaluation of renal perfusion in health and disease, both in human and veterinary medicine. Renal scintigraphy using Tc-

Estimating a regional ventilation-perfusion index [PDF]

Physiological Measurement, 2015
This is a methods paper, where an approximation to the local ventilation-perfusion ratio is derived. This approximation, called the ventilation-perfusion index since it is not exactly the physiological ventilation-perfusion ratio, is calculated using conductivity reconstructions obtained using electrical impedance tomography.
