| Abstract: | Systolic, diastolic, and mean arterial blood pressures and heart rate were determined in 73 horses, using an indirect automatic oscillometric technique. Blood pressure and heart rate data obtained by sphygmomanometry were compared with similar data obtained from cannulation of the horses' facial or dorsal metatarsal arteries. Good correlation between direct (actual) and indirect (oscillometric) blood pressures and heart rate measurements were obtained when the heart rate was low, using high sensitivity setting. Cardiac arrhythmias or hypotension prevented oscillometric measurements from being obtained in 9 (12%) horses. |
