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 ...

Prediction of intraoperative arterial hypotension associated with the spinal anesthesia. Prospective observational study

Инновационная медицина Кубани, 2023
Background: 90% of C-sections are supported by spinal anesthesia, which is complicated by arterial hypotension in 60%-80% of cases. The perfusion index seems to be a significant prognostic tool for arterial hypotension.Objective: Тo confirm the value of ...

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.

Prevalence and clinical significance of cardiovascular magnetic resonance adenosine stress-induced myocardial perfusion defect in hypertrophic cardiomyopathy

Journal of Cardiovascular Magnetic Resonance, 2020
Background Hypertrophic cardiomyopathy (HCM) is thought to be associated with microvascular dysfunction. Adenosine stress-perfusion cardiovascular magnetic resonance imaging (CMR) is a sensitive method for assessing microvascular perfusion abnormalities.
