[The plotting of intraventricular pressure-volume diagrams using intracardiac impedance volumetry].

The theoretical and practical aspects of a method for continuous measurements of the left ventricular volume are reviewed. The method is based on high frequency intracardiac impedance measurements. The mathematic model, results of computer simulation are given as are equations for calculating the volume of the left ventricle of the heart. A computer program for measurements automation and the plotting of intraventricular pressure-volume diagrams is described.

[A comparative study of five pulse oximeters].

The pulsed oximeters "Satlite" and Satlite Trans" (Datex, Finland), "Biox-3700' (Ohmeda, USA) "OXI" (Radiometer, Denmark), "Danamap-Oxytrak" (Critikon, Johnson & Johnson, USA) are essential and highly precise devices for controlling vital functions of the body during anesthesiologic techniques. The delay time of a response of the pulsed oximeters "Satlite Trans" and "Box-3700" in providing the values of the saturation of arterial blood hemoglobin with oxygen is 40 sec. The pulsed oximeter-personal computer system opens up new possibilities of increasing the quality of monitoring and safety of bronchoscopic studies and operations and allows a protocol of the intervention to be developed.
