Critical care is provided for patients who are suffering from life-threatening conditions. The doctors who work with these people are often called intensivists. They focus on a range of different issues, so they can serve people who need immediate and life-saving care. Since people who need critical care are suffering from such a wide variety of issues, intensivists must have a thorough understanding of diverse types of medical issues and the devices and medications needed to treat them.

A vascular surgeon is a medical professional who has been trained to diagnose and treat diseases of the vascular system. The vascular system is made up of blood vessels and veins.
