The laboratory also contains patient monitors, pulseoximeters, fetal monitors (2) and ultrasound.


The Biofluid Mechanics Laboratory (BH 106) is used primarily for research, but is also used to teach the senior biomedical engineering laboratory course.


Research Facilities

A number of research laboratories complement the instructional program.These facilities serve as resources to our students and contribute significantly to the outstanding educational environment that exists in Biomedical Engineering.


The Biofluid Mechanics Laboratory (Bogard Hall 106) is used to measure velocities and flows in models of arteries. The models may be three-dimensional representations of human artery bifurcations, or they may be more idealized models which are used to study specific responses of blood-borne or vascular cells. The purpose of the laboratory is to determine the hemodynamic mechanisms involved in arterial adaptation and disease. The laboratory includes laser Doppler velocimetry equipment, a cone-in-plate viscometer, a data acquisition computer, a Pentium personal computer which runsAutocad, ultrasonic equipment, an anti-vibration table, spatial analyzer, physiological pressure transducers, two Carolina medical EMF flow meters, a transit time flow meter, model manufacturing facilities, and a distilled water generator.


The Tissue Engineering and Cell Culture Laboratory (Institute for Micrmanufacturing) has been designed to investigate the effects of hemodynamic phenomena on the behavior of vascular cells, (endothelial cells, platelets, smooth muscle cells, osteoblasts) as related to atherosclerosis, intimal hyperplasia, thrombosis, bone growth, and micromanufactured cell substrates. The lab includes a laminar fume hood, an environmentally-controlled flow chamber, an imaging microscope, an injection-flow apparatus (syringe pump), an incubator, a centrifuge, a refrigerator, and a plate reader. The lab is jointly funded by CyBERS and the School of Biological Sciences.


The Rehabilitative Neuroscience Laboratory (VAMC-Shreveport) is used to quantify human movement especially as it relates to spasticity and joint biodynamics. Equipment in this laboratory includes devices to deliver precise displacement or torques to the ankle, knee or shoulder joints. Portions of this laboratory are located at the V.A.MedicalCenter in Shreveport where palmtop computers are used as interface devices for quantifying spasticity.


The SLIP/FALLS Laboratory (VAMC-Shreveport and CyBERS Room 400) is used to study the psychophysics of balance and neurologically intact and neurologically impaired states. Equipment in this laboratory includes the Sliding Linear Investigative Platform For Assessing Lower Limb Stability (SLIP/FALLS) which is capable of making vibration-free linear translations from 5 ?m to 12 cm at accelerations of up to 2.5 mm/sec2. This lab also has a Tek-Scan pressure-sensitive floor mat system. This laboratory is presently at the VAMC-Shreveport and is being duplicated at CyBERS.


The Electrode Fabrication Laboratory (CyBERS 207) is used to build nitric oxide, pH and oxygen glass electrodes (microsensors). The hardware available includes microscopes, a computer-controlled horizontal electrode puller, an electrode beveler, electroplating apparatus, and various types of meters used in the process. This laboratory may be used to calibrate, test and use pH electrodes (microsensors). Equipment available includes a computer monitored dual electrometer, chart recorder, water bath, balance, and manipulators, and basic trouble-shooting equipment.


The Mass Transport Laboratory (CyBERS 209) contains one experimental work station and contains the equipment to study oxygen mass transport in brain slices, heart papillary muscle, and oxygen microbubbles. Equipment includes a computer monitored and controlled piezoelectric manipulator, picoammeter, vibration isolation apparatus, water bath and recording equipment.
