Effects Of Beet Supplements On Cardiovascular Response Using A Noninvasive Blood Pressure Cuff, Nicholas M. Hughes
Effects Of Beet Supplements On Cardiovascular Response Using A Noninvasive Blood Pressure Cuff, Nicholas M. Hughes
Master's Theses
A Calibrated Cuff Plethysmography device was built, tested for verification, and used to experiment on human subjects to measure the cardiovascular response of consuming a beet supplement, specifically looking at arterial compliance and pressure-area curves. Each subject was tested four times. A baseline was measured under normal conditions and after five-minute hyperemia conditions. 10 subjects were given 6 ounces of water mixed with either purple Kool-Aid (control), a SuperBeets supplement, or a SuperBeets Sport supplement and after 45 minutes, measurements were taken undergoing normal and hyperemia conditions once more. The verification testing demonstrated the calibration of the device was effectively …
The Effect Of Neurostimulation On Blood Flow And Ischemic Pain, Stacey M. Fishman
The Effect Of Neurostimulation On Blood Flow And Ischemic Pain, Stacey M. Fishman
Biomedical Engineering
Chronic pain caused by lack of blood flow is known as ischemic pain. Neurostimulation, the application of electrical currents through a region of the body, is effective for pain modulation, and it is hypothesized that this can be explained by the gate control theory and alterations of the sympathetic output initiated by the metaboreflex. The decrease of sympathetic output reduces vasoconstriction and improves blood flow. Transcutaneous electrical nerve stimulation (TENS) and interferential currents (IFC) stimulation, both non-invasive neurostimulation techniques, were evaluated for their effects on cutaneous blood flow on the palm. High or low frequency TENS and/or IFC, and the …
