    A technique is described for measuring regional blood flows in the brain of the cat. The measuring system is based on the principle of photoelectric plethysmography, a method commonly used to measure skdn blood flow. To miniaturize the photoelectric flow probe to a size compatible with cerebral insertion, a light emitting diode (LED) was used as the light source and a photo-Darlington array was us...

    We have developed and tested a portable device that analyzes the electroencephalogram (EEG) to determine if petit mal epilepsy waveforms are present. Clinicians should rimd it useful in diagnosing seizure activity of their patients. The micropower, battery-operated, portable device indicates a seizure has occurred if three criteria are satisfied: 1) frequencies of 2.5-7 Hz, 2) large amplitude wave... View full abstract»

    The accuracies of five commercially available small flat pressure transducers (~5 mm ×~1 mm) were evaluated for their ability to measure pressures applied to the body surface. The diaphragms of the transducer were loaded with rubber and cloth surfaces in an in vitro test and under a blood pressure cuff over the gastrocnemius muscle, 2 cm on the medial and lateral sides of the tibia and on the tib...

  • A Simple Device for Closed Loop Heart Rate Control During Cardiac Rehabilitation

    During unsupervised exercise for cardiac rehabilitation or conditioning, it is desirable to reach and maintain a predetermined heart rate (without overshooting) selected according to age, health, and cardiac status of the patient. Because there is no simple and inexpensive heart rate controller, most exercise protocols are specified in terms of patient work load-often speed and torque of a station... View full abstract»

    The in vivo measurement of specific impedance in brain tissue involves several technical aspects. The most stringent difficulties relate to electrode polarization and spatial resolution of the measuring system. The polarization is solved by usinga four electrode arrangement with a very high impedance preamplifier on the potential electrodes. This paper discusses the relative effectiveness of the v...

  • The Effect of Electromyographic Jitter on Single Motor Unit EMG Potentials

    Variability between successive discharges of the single motor unit potential in the biceps brachii muscle, due to electromyographic (EMG) jitter, has been investigated. This jitter results from random arrival times of single fiber potentials at the electrode. A computer model has been used to generate single motor unit potentials incorporating the effects of EMG jitter. A computed variance peak wa... View full abstract»

  • Spectral Analysis of Auditory Evoked Potentials with Pseudorandom Noise Excitation

    Publication Year: 1979, Page(s):479 - 487

    Pseudorandom noise (PRN) of various bandwidths was used in testing both normal and hearing impaired subjects by means of auditory-evoked potentials (AEP's). The AEP's were studied in the frequency domain via spectral analysis rather than in the time domain as is often done. Spectral analysis provides such system features as power spectral densities (PSD's) and transfer and coherence functions. The... View full abstract»

    A rhinomanometer for routine use is described measuring the nasal airflow V with a Prandtl-type tube. V2 can be plotted in dependence of the transnasal pressure Δp yielding a straight line in normal cases. Furthermore, the instrument measures Δp/V2 from which the nasal flow resistance can be deduced directly without a plotter. View full abstract»

  • Computation of Respiratory Resistance, Compliance, and Inertance from Forced Oscillatory Impedance Data

    Relationships for computing total respiratory resistance, compliance, and inertance from the frequency dependence of forced oscillatory impedance are presented. These equations result by minimizing the sum squared difference between the experimental impedance data and the response of the model. View full abstract»

    Closed circuit anesthesia systems offer certain advantages over other techniques, but require that gas administration closely foliow the uptake by the body, which is proportional to the square root of time. We have developed a timer which automatically signals the anesthesiologist to readjust the gas flow at selected intervals to provide a stepwise approximation to the square root of time curve. T...
