3. Blood pressure and heart rate management: The ICU team closely monitors a patient's blood pressure and heart rate to ensure they remain stable.

4. Pain management: Patients in the ICU are given pain relief to make them as comfortable as possible.

5. Nutritional support: Patients who are unable to eat or drink on their own receive nutritional support through a feeding tube or IV.

6. Medication management: The ICU team manages patients' medications, ensuring they receive the right dose at the right time.

7. Infection control: The ICU is designed with infection control measures to prevent the spread of disease.

8. Family support: The ICU team works closely with families to provide support and information about their loved one's condition.
