Dedicated in 1993, New Bolton Center clinicians were pioneers in the use of the high-speed treadmill. It can hit speeds of up to 45 miles per hour, which makes it ideal for evaluating racehorses. It can also be used for sport horses, draft horses, and ponies—any horse that needs assessment while exercising.
Examination during treadmill exercise allows us to instrument and evaluate the horse while trotting, pacing, or galloping, looking at multiple body systems all at once: heart, upper airway, lungs, and musculoskeletal systems.
Treadmill testing includes:
- Exercising upper airway endoscopy
- Exercising electrocardiogram (ECG), to measure heart rate and rhythm
- Echocardiogram, an ultrasound of the heart
- Arterial blood gas analysis – New Bolton Center is one of the only equine clinics in North America that conducts exercising arterial blood gas analysis on a treadmill, using catheters to obtain multiple samples to measure blood oxygen levels.
- Bronchoalveolar lavage (BAL), fluid analysis from the lungs
- Electrolyte, muscle enzyme, and lactate analysis
