New Finger-Occlusion Plethysmograph for Estimating Peripheral Blood Flow and Vascular Resistance

Impaired Erythrocyte Filterability of Spontaneously Hypertensive Rats: Investigation by Nickel Mesh Filtration Technique

“…38 Moreover, absolute peripheral blood flow is reduced in human hypertension 39 because of high blood viscosity 40 and abnormal erythrocyte rheology, such as reduced membrane fluidity, 41 and an elevated erythrocyte free Ca 2+ concentration. 42 This line of evidence implies that circulating erythrocytes of hypertensive patients experience persistent inflammatory damage and shear stress, which impairs erythrocyte filterability by signal transduction involving intracellular Ca 2+ .…”

Measurement of Hemodynamics During Postural Changes Using a New Wearable Cephalic Laser Blood Flowmeter

“…16 We developed a wearable cephalic BF (CBF) meter incorporating an ultra-miniature laser-Doppler blood flowmeter that can be worn on the tragus of the external ear to measure CBF during postural changes. 17,18 In the present study, we used this devise to estimate systemic hemodynamic parameters and symptoms of cephalic ischemia.…”
