Abstract:
Severe hypotension was produced in 8 dogs during halothane anesthesia. Three monitors detecting respiratory rate, Doppler signal and pulse rate were compared to direct blood pressure measurements. Deep anesthesia was most consistently detected using the respiratory monitor. The signal fade of the Doppler device was best at detecting hypotension from blood loss. Changes in heart rate were not useful.
