What must be monitored during anesthesia for effective management?

During anesthesia, effective management requires monitoring ventilation and oxygenation to ensure the patient maintains adequate respiratory function and proper oxygen delivery. Monitoring these parameters is vital because any compromise in ventilation or oxygenation can lead to serious complications such as hypoxia or respiratory failure.

While patient weight, eye reflexes, and heart rate may be relevant factors in assessing a patient's overall condition or anesthetic depth, they do not provide comprehensive oversight of the key physiological functions required during anesthesia. For example, knowing just the heart rate or eye reflexes does not give complete insight into whether the patient is adequately ventilating or appropriately oxygenated. Thus, focusing on ventilation and oxygenation supports a higher standard of safety and efficacy during anesthetic procedures.
