摘要： A method is provided for predicting that a caregiver will order a blood transfusion during a treatment. The method includes obtaining, on a processor, first data that indicates values for one or more parameters of a characteristic of a peak of a Fourier transform of a continuous photoplethysmographic (PPG) waveform or a continuous electrocardiogram (ECG) waveform or both collected during the treatment. The method further includes applying, on the processor, coefficients to the values for the one or more parameters. The method further includes determining, on the processor, second data that indicates a prediction that the caregiver will order the blood transfusion during the treatment based on applying the coefficients to the values. The method further includes presenting on a display device output data based on the second data. An apparatus is also provided for predicting that the caregiver will order the blood transfusion during the treatment.

摘要： Techniques for automated surgeon performance evaluation include dressing an operator with colored surgical gloves. A first glove for a dominant hand has a first color and a second glove for the other hand has a different second color. Video data that views the operator's hands is captured during a surgical procedure on a subject. For each of multiple frames of the video data, a minimum rectangle of pixels, called a first rectangle, which encloses pixels having the first color, is determined automatically on a processor. A first time series for a representative property of the first rectangle at the multiple frames, and a first measure of entropy based on the first time series, are also automatically determined on a processor. A metric of operator performance based at least in part on the first measure of entropy is stored, e.g., for subsequent display.
