Recognizing hypotension due to bupivacaine overdose primarily focuses on monitoring blood pressure readings. Bupivacaine, a local anesthetic, can lead to cardiovascular toxicity, which includes hypotension as a significant clinical manifestation. In the context of an overdose, the body's ability to maintain normal blood pressure is compromised, resulting in low blood pressure readings.

Monitoring the blood pressure will typically reveal hypotension, which is characterized by systolic readings that are significantly lower than the normal range. The recognition of this condition is critical, as it can lead to further complications affecting vital organ perfusion. Therefore, the observation of low blood pressure is a direct and critical indicator of bupivacaine overdose leading to hypotensive episodes.

Other physiological responses, while they may occur with an overdose, do not serve as the primary means of identifying hypotension. For instance, elevated blood pressure would contradict the diagnosis, while reduced heart rate and increased respiratory rate may not specifically indicate hypotension linked to bupivacaine. Instead, they could reflect other aspects of the patient's response to the medication or the overall physiological response to stress or anesthetic effects.
