MONITORING OF SUBJECTS DURING AVALANCHE SNOW BREATHING EXPERIMENTS: POSSIBLE ERRORS
Original language description
The gas exchange and work of breathing in avalanche burial victims have been a subject of numerous field experiments with healthy volunteers. The vital sign monitors used in monitoring of subjects during these experiments have to work in non-standard ambient conditions, outside the programmed physiological limits and may affect the accuracy of the measurements. In order to assess the reliability of pulse oximetry as a monitoring method of experimental subjects, we used five different pulse oximeters to monitor 12 healthy volunteers during a trial, in which they were breathing into simulated avalanche snow. In the course of the trial when desaturation occurred, we observed significant discrepancies in oxygen saturation readings among the oximeters—in the rate of desaturation, and in the lowest recorded values. These observations suggest that relying on a single parameter which is SpO2 as a study endpoint, or as a safety measure, may present a possible safety risk. In future avalanche trials, endpoints should be set on the basis of more parameters and continuous clinical assessment.
