RESUMO
The method for studying the effects of weak magnetic fields and "magnetic vacuum" on the psychophysiological state of a human organism is proposed. This method includes the system of the exposure of a human organism to uniform constant and alternating magnetic fields and the system of computerized psychological tests. The influence of the weakening of constant magnetic field on the psychophysiological state of human organisms was studied. The short-term color memory and reaction rates of 30 subjects have been examined in the local geomagnetic field and in a magnetic field which was reduced in 10 and more times. Statistically significant differences in the color memory test was found in the magnetic field 4 +/- 1 microT in comparison with the results in the geomagnetic field. In the magnetic field 0 +/- 1 microT, slight impairment of color memory was found. Preliminary results in the test of reaction rates showed the tendency to slowing down the reaction rates in the weakened magnetic fields.

Recent comments and amendments to routine algorithm of P. Safar's cardiopulmonary resuscitation, known as the ABCD principle, are critically analyzed. The primary mechanisms of thanatogenesis in sudden death in the majority of cases are not respiratory problems (requiring ABCD algorithm), but cardiac rhythm disorders. Based on their studies and practical and training experience, the authors suggest a new algorithm of cardiopulmonary resuscitation: UNIVERSAL, with the following steps: precordial stroke, indirect massage of the heart, forced ventilation of the lungs, venipuncture, electrocardiography, defibrillation by electric pulse therapy, electrocardiostimulation, and injections of adrenalin, atropine, and lidocaine. Introduction of this algorithm decreased hospital mortality of acute coronary patients, increased the rate of reanimation of suddenly dead patients, and reduced the incidence of iatrogenic complications of resuscitation.
