Figure 3

Heart and respiration rates determined by adaptive and non-adaptive Kalman filter with PPG and flow reference using the SE setting. Heart (top) and respiration (bottom) rates determined by adaptive (red) and non-adaptive (blue) Kalman filter with PPG and flow reference (gray) using the SE setting for subject 1 (left column) and 2 (right column). The dotted gray lines indicate the starting frequencies of the heart and respiration rates defined in the setting at startup.
