FIG. 9.

Vital signs of dog S473 (18 kg) around the time of vector administration. Temp, temperature (°F); SpO₂, percent oxygen saturation measured by pulse oximetry; HR, heart rate (bpm); BP, systolic blood pressure measured by Doppler ultrasound (mmHg); RR, respiratory rate (rpm). Circles in the respiratory rate plot indicate mechanical ventilation. The time scale on the x axis between 10:20 and 10:40 is doubled to accommodate additional data points. Times of propofol boluses, lidocaine administration, and vector infusion are shown.
