Monitoring parameters during anesthesia is crucial for ensuring patient safety and effective management throughout the surgical procedure. The selection of heart rate, oxygen saturation, and end-tidal carbon dioxide measurement as essential monitoring parameters encompasses a comprehensive view of the patient’s physiological status.

Heart rate is vital as it provides insight into cardiac function and the body's response to anesthesia, drugs, and surgical stress. Changes in heart rate can indicate complications such as bradycardia or tachycardia.

Oxygen saturation is a key measure of the patient’s respiratory function and indicates how well oxygen is being transported in the blood. Monitoring oxygen saturation ensures that the patient is receiving adequate oxygenation, which is critical during anesthesia because respiratory function can be compromised.

End-tidal carbon dioxide levels reflect the adequacy of ventilation and can provide immediate feedback about the patient’s respiratory status. Monitoring this helps in detecting hypoventilation or hyperventilation, allowing for timely interventions to maintain appropriate carbon dioxide levels in the blood.

Together, these parameters offer essential information about cardiovascular and respiratory status, which are fundamental during anesthesia to prevent adverse events and maintain homeostasis. The other options do not provide the same comprehensive assessment of these critical systems during anesthesia.
