Ultrasonic measurement of arterial blood pressure in conditioned thoroughbreds
Insights
Indirect blood pressure was measured in 456 Thoroughbred horses. Mean systolic pressure was 111.8 mmHg and mean diastolic pressure was 69.6 mmHg, establishing baseline values for equine cardiovascular health.
Area of Science:
- Equine Medicine
- Cardiovascular Physiology
- Veterinary Diagnostics
Background:
- Understanding arterial blood pressure is crucial for assessing equine health.
- Previous data on Thoroughbred horse blood pressure is limited.
- Establishing reference ranges aids in early detection of cardiovascular conditions.
Purpose of the Study:
- To determine indirect systolic and diastolic arterial pressure values in Thoroughbred horses.
- To establish reference ranges for blood pressure in this specific equine population.
- To provide data for veterinary diagnostic and research purposes.
Main Methods:
- Utilized an ultrasonic-Doppler device combined with a sphygmomanometer cuff for non-invasive measurements.
- Measured arterial blood pressure in 456 Thoroughbred horses of diverse ages and sexes.
- Collected data from horses stabled at 9 distinct race tracks.
Main Results:
- The mean systolic arterial pressure was recorded as 111.8 ± 13.3 mmHg.
- The mean diastolic arterial pressure was recorded as 69.6 ± 13.8 mmHg.
- These values represent the average blood pressure within the studied population.
Conclusions:
- The study provides essential reference values for indirect systolic and diastolic arterial pressure in Thoroughbred horses.
- These findings can assist veterinarians in evaluating the cardiovascular status of racing horses.
- This data contributes to the broader understanding of equine physiological parameters.
Abstract:
Indirect systolic and diastolic arterial pressure measurements of 456 Thoroughbred horses of various ages and sex stabled at 9 different race tracks were measured with an ultrasonic-Doppler device interfaced with a sphygmomanometer cuff. The mean systolic pressure was 111.8 +/- 13.3 mmHg and the mean diastolic pressure was 69.6 +/- 13.8 mmHg in this population.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
