Electronic control devices (including the Advanced TASER(®) X26 model produced by TASER International) incapacitate individuals by causing muscle contractions. To provide information relevant to development of future potential devices, effects of monophasic square waves with different parameters were compared with those of the X26 electronic control device, using two animal models (frogs and sw...

Introduction. Compound Muscle Action Potential (CMAP) scan is a noninvasive promissory technique for neurodegenerative pathologies diagnosis. In this work new CMAP scan protocols were implemented to study the influence of electrical pulse waveform on peripheral nerve excitability. Methods. A total of 13 healthy subjects were tested. Stimulation was performed with an increasing intensities range...

BACKGROUND The management of the pulseless perfused hand in association with a supracondylar humerus fracture following operative stabilisation remains controversial. Previous authors have suggested the use of color-flow duplex monitoring, magnetic resonance angiography and segmental pressure monitoring as objective steps to ascertain blood flow following adequate internal fixation. We examine ...

OBJECTIVES : A systematic review of the literature to determine the ability of dynamic changes in arterial waveform-derived variables to predict fluid responsiveness and compare these with static indices of fluid responsiveness. The assessment of a patient's intravascular volume is one of the most difficult tasks in critical care medicine. Conventional static hemodynamic variables have proven u...

Arterial stiffness is one of the most important determinants of increased systolic arterial pressure and pulse pressure, and is closely associated with hypertension, hyperlipidemia, type 2 diabetes melli-tus, and artery hardening (1-2). The American College Sports Medicine guideline states regular exercise can prevent and treat cardiovascular system dysfunction including arterial stiffness (3)....

This study presents a new type of pulse auscultation system, which uses a condenser microphone to measure pulse sound waves on the wrist, captures the microphone signal for filtering, amplifies the useful signal and outputs it to an oscilloscope in analog form for waveform display and storage and delivers it to a computer to perform a Fast Fourier Transform (FFT) and convert the pulse sound wav...

Aortic blood pressure is more meaningful than brachial blood pressures for clinical diagnosis, and ambulatory blood pressure monitoring is better predictor for the outcomes than clinical blood pressure monitoring. However, there are few devices which provide continuous central blood pressures and arterial stiffness noninvasively. In this study, pressure sensors were developed to detect two radi...
