Principally, Laser Doppler Flowmetry (LDF) makes use of the fact that when a coherent, low-powered laser illuminates tissue, light is scattered in static structures as well as in moving blood cells within the microcirculatory beds. Photons, scattered by the moving blood cells, are spectrally broadened according to the Doppler effect. LDF is established as an […]
The nasal skin and mucosa are often subject to allergic reaction. To evaluate micro-vascular blood flow of the skin, standard surface probes (TSD146) are suitable. To perform measurements on the nasal mucosa, use needle probes (TSD144, TSD145) with the appropriate clamp. Flow max Flow min Mean flow Heart rate
Use the powerful Epoch Analysis data reduction function to reduce large (24-hour) data files to manageable sizes. Analyze both primary signals (such as arterial blood pressure) and derived data (such as Systolic BP). Extract basic measurements from fixed width segments of data. Set “epoch” width to any time interval and key off of scored event […]
Laser Doppler monitoring of cerebral blood flow can be performed with many different types of fiber-optic probes, dependent on the size and location of the area to be investigated. To measure subcutaneous micro-vascular blood flow, use needle (TSD144, TSD145) or disposable fiber (TSD147A or TSD147AL) probes. For cutaneous measurements, use surface (TSD140 or TSD146) or suturable […]
Evaluate skin reactions resulting from hypersensitivity and inflammatory mediators. To measure micro-vascular blood flow on the skin surface, use the TSD140 or TSD146 probes. To objectively quantify the flow changes resulting from inflammation, take a real-time measurement of the mean or median value of the LDF100C flow signal. Flow max Flow min Mean flow Heart rate
Full Online Pulsatile Flow Data Analysis The software will provide full online analysis of pulsatile flow data for each cardiac cycle. Use the automatic data reduction function to determine statistical measurements over a user-defined time period.
Flaps and planted tissues typically exhibit changes in blood flow after the planting procedure. The MP System can be programmed to control a visual or auditory alarm if the mean or peak-to-peak blood flow signals from the LDF100C drop below a specified level. Use AcqKnowledge to isolate pulsatile signals and evaluate the peak-to-peak values in real […]
Research the micro-vascular blood flow changes resulting from different rheumatic disorders, such as rheumatoid arthritis, Raynauds phenomenon and connective tissue disease. For investigations of Raynauds phenomenon, use the digit probe (TSD142). To assess ischemia of the small intestine, use needle probes (TSD144, TSD145).
The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level […]
View AllNIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
A System to Measure Physiological Response During Social Interaction in VR Children with Autism Spectrum Disorder (ASD) have a difficult experience in responding to social cues and actions. This pilot study measured the effectiveness of Virtual Reality in creating a social environment for children, measured with a BIOPAC MP Series data acquisition system and Worldviz […]
