P02.29. Laser Doppler perfusion imaging to test effects of Lifewave energy enhancer patch on microvascular regulation
نویسنده
چکیده
Purpose LifeWave Corp has developed non-transdermal energy enhancer patches that stimulate acupuncture points in order to heighten energy by enhancing the autonomic regulation of blood vessels and hence improving circulation. A laser Doppler perfusion imager was used to determine microvascular perfusion of the index, middle and ring finger tips pre and post application of the patches on wrist acupuncture points TB5 and P6. It was hypothesized that application of the patches would significantly alter perfusion in fingertips.

BACKGROUND: When measuring skin blood perfusion with laser-Doppler methods in a limb, a non-zero perfusion is sometimes registered even when the arterial inflow to, and venous outflow from the site of measurement is arrested using proximal cuff compression pressures well in excess of systolic blood pressure. This residual signal, known as the biological zero (BZ)1-7, is present to some extent w...

BACKGROUND Anesthetic agents alter microcirculation, influencing tissue oxygenation and delivery of vital substrates. Laser Doppler perfusion imaging is a widespread technique in the field of microvascular research that can evaluate noninvasively and in real time the effects of environmental conditions, physical manipulations, diseases and treatments on peripheral perfusion. This study aims to ...

Cutaneous microvascular responses to physiological stimuli are currently being investigated as indices of vascular function and to monitor responses to therapy. We attempted to systematically assess various microvascular cutaneous flow indices in response to reactive hyperaemia in control subjects and in patients with coronary artery disease (CAD), and to correlate these with brachial artery fl...
متن کاملMicrovascular imaging: techniques and opportunities for clinical physiological measurements.
The microvasculature presents a particular challenge in physiological measurement because the vessel structure is spatially inhomogeneous and perfusion can exhibit high variability over time. This review describes, with a clinical focus, the wide variety of methods now available for imaging of the microvasculature and their key applications. Laser Doppler perfusion imaging and laser speckle con...
