Critical care surgeons usually work under highly stressful conditions, requiring them to respond quickly to life-threatening situations. They also typically have more extensive training, including medical school, surgical residency, and additional specialized training in critical care.

All of these factors contribute to why critical care surgeons typically earn higher salaries compared to family doctors.
