Which parameter must be recorded every 15 minutes during general anesthesia?

Monitoring pulse rate every 15 minutes during general anesthesia is crucial for assessing the adequacy of cardiac function and the overall physiological response of the patient. The pulse rate provides immediate information about the patient's heart activity, indicating whether the anesthetics are affecting the cardiovascular system. Changes in pulse rate can be indicative of various complications, such as bradycardia or tachycardia, which may arise from anesthetic agents or the patient’s response to the procedure.

Regular monitoring helps ensure that any abnormalities in heart function can be addressed promptly, thereby contributing to the safety and effectiveness of the anesthesia protocol. While other parameters, such as temperature, respiratory rate, and mean arterial pressure, are essential for comprehensive monitoring, pulse rate is particularly time-sensitive in the context of anesthesia management, requiring frequent observation to ensure the patient remains stable throughout the procedure.
