5/30 What is the purpose of EEG monitoring during surgery? To ensure patient comfort To measure heart rate To replace ECG To monitor brain activity

The correct answer is **To monitor brain activity**. Here's why:* **EEG (Electroencephalogram)** is a medical test that measures the electrical activity of the brain. * **During surgery**, especially brain surgery or procedures involving the nervous system, EEG monitoring is crucial for: * **Detecting changes in brain function:** This helps surgeons identify potential complications like seizures, ischemia (lack of blood flow), or brain swelling. * **Guiding surgical interventions:** EEG can help surgeons avoid damaging critical brain areas. * **Monitoring anesthetic depth:** EEG can help anesthesiologists adjust medication levels to ensure the patient is adequately sedated.**The other options are incorrect:*** **To ensure patient comfort:** While patient comfort is important, EEG is not directly used for this purpose.* **To measure heart rate:** Heart rate is measured by an ECG (Electrocardiogram), not an EEG.* **To replace ECG:** EEG and ECG measure different things and are not interchangeable.
