Blood Cell Aggregation and Screen Filtration Pressure

Blood cell aggregation and screen filtration pressure.

Blood Cell Aggregation and Screen

RECENT investigations of the conjunctival and nail-bed microcirculation indicate that certain changes in the small blood vessels and the circulating blood are frequently associated with disease. Straight, unkinked arterioles, tortuous veins, and micropools have been observed by Landau and Davis' in subjects with arteriosclerosis. Congestion of the venules and capillaries are seen in diabetes me...

Comparing the Effect of Simple Filtration Hemodialysis and Ultrafiltration Hemodialysis on Arterial Oxygen Saturation and Blood Pressure in Chronic Dialysis

Background and purpose: Hypoxemia and hypotension are important complications of hemodialysis in patients with chronic renal failure that are linked to several factors, including the type of filters used. The aim of this study was to compare the effect of simple filtration hemodialysis and ultrafiltration hemodialysis on blood pressure and blood arterial oxygen level. Materials and methods: In...

Continuous blood cell separation by hydrophoretic filtration.

We propose a new hydrophoretic method for continuous blood cell separation using a microfluidic device composed of slanted obstacles and filtration obstacles. The slanted obstacles have a larger height and gap than the particles in order to focus them to a sidewall by hydrophoresis. In the successive structure, the height and gap of the filtration obstacles with a filtration pore are set betwee...

Significance of blood pressure in infancy. Familial aggregation and predictive effect on later blood pressure.

Blood pressure was measured in 730 infants and their mothers within 5 days of birth. Paternal blood pressures were obtained where possible, and follow-up measurements were made on participants at 1 week and 1, 6, 12, 18, and 24 months. Infant blood pressures were adjusted for such variables as age, observer, cuff size, and sleep/activity status. Infant blood pressure correlated with maternal bl...
