Blood pressure (BP) is a key biomarker that is frequently used in non-ambulatory settings by medical professionals to assess cardiovascular status2. However, conventional ambulatory BP measurements are taken with a sphygmomanometer device operating on an inflating cuff that is bulky and intrusive. ...
24-hour ambulatory blood pressure monitoring (ABPM) ABPM was conducted using validated Spacelabs model 90207 or 90227 monitors (Spacelabs, Snoqualmie, WA)21,22,23. Participants were fitted with the appropriate size BP cuff on the non-dominant arm. Monitors were initialized to define daytime as ...
In general, arterioles control blood flow and pressure, capillaries mediate entry and exit of molecules from the CNS parenchyma and modulate local blood flow in response to stimuli, and venules mediate immune cell invasion [5, 27,28,29]. Whether the apparent greater impact of aging on SC ...
of varying skin tones (Fitzpatrick skin type I to VI) by either completely occluding the arterial inflow of blood (arterial or total occlusion, BOP ≈ 140 mmHg) or by only stopping the venous back-flow of blood (venous or partial occlusion, BOP ≈ 70 mmHg) using the manual pressure cuff...
Human cerebral oxygenation and hemodynamics can be estimated by cerebral oxygenation parameters. Functional near-infrared spectroscopy (fNIRS) can be used to measure the hemoglobin concentration index of brain tissue noninvasively and in real time. Howev
