    Deals with the problem of bypass surgery. The authors examine the basic mechanical and physiological problems of the heart and lung. They assume that the cardiopulmonary bypass is a technique by which the pumping action of the heart and the gas exchange functions of the lung are temporarily replaced by a mechanical device; the pump oxygenator attached to the vascular system of the patient.

    Calcium apatite powder was formed and a definite quantity was mixed separately with 1% solutions of gelatin, chitosan and collagen to form a paste. The gelatin apatite mixture flowed easily while the collagen apatite one was too viscous. The paste formed by the different mixtures was packed individually in thin plastic tubes and calcined at 800°C. The ashing away of the organic matter and the ... View full abstract»

    Phonocardiography can be defined as the method for obtaining recording of cardiovascular sound. Laennec (1781-1826) was the first to listen to the sounds of the heart. He invented the stethoscope and provided the basis of contemporary ascultation. As physiological knowledge increased through the following decades, faulty interpretations of heart sounds were progressively eliminated. The first tran... View full abstract»

    Magnetic stimulation has introduced a new dimension in clinical neurology. The painless and non invasive cortical stimulation permits diagnosis of lesions in the central nervous system (CNS). It is well suited for deep peripheral nerves such as the lumbar and cervical roots. This method of stimulation is very safe as there is no direct contact between the patient and stimulating electrodes. When t... View full abstract»

  • A new error criterion for ECG data compression

    Publication Year: 1995, Page(s):2/62 - 2/63
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (156 KB)

    In many compression techniques the m.s.e (mean square error) criterion is used, a choice normally made because of mathematical convenience. However, for the ECG application this error criterion is unsatisfactory since it does not reveal whether or not an algorithm can preserve diagnostically significant features of the waveforms. There are many defects with it. For this reason the authors present ... View full abstract»

    The changes in power spectrum of stable EEG from subjects who have listened to pure-tones-pair and a phonetic sound are found to be different and specific. A pure-tones-pair induction leads to the increase in the amplitude of the power spectrum in temporal region whereas the phonetic induction leads to the increase in the amplitude of the power spectrum in the frontal and the occipital regions.

    Detection of the fracture of a bone at a site, say during an accident, is a serious problem, these days. In the present paper a new technique is presented. This is low cost and electrical in nature. The electrical conductivity of the bone varies from radial direction to the direction parallel to the bone axis. This confirms that bone has electrically anisotropic behaviour. The induced e.m.f. gener... View full abstract»
