[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.
