Which value represents the tachycardia threshold for the Cow during stage III anesthesia?

• A. 90 bpm
• B. 100 bpm
• C. 110 bpm
• D. 120 bpm

Answer: (B)

In this context, the value used to define tachycardia during stage III anesthesia is the heart rate that marks when the cow is considered tachycardic. A resting heart rate for cattle is roughly 60–80 beats per minute, and anesthesia often lowers heart rate further. When the heart rate reaches about 100 beats per minute or more, it is typically treated as tachycardia. This 100 bpm threshold is used clinically as the cut-off to prompt evaluation for possible light anesthesia, pain, hypovolemia, or other distress. Values below 100 bpm are generally not considered tachycardic in this scenario, while higher values (110 or 120 bpm) indicate more pronounced tachycardia but the standard threshold remains 100 bpm.
