Critical care is medical care for patients whose illness requires close, constant watch by a team of specially trained caregivers. Most critical care takes place in an intensive care unit (ICU) or a trauma center. Both places of care contain all kinds of machines, tubes, and equipment used to treat the illness.
Feeling scared in the ICU is natural. You may be meeting the care team for the first time, or you may not recognize the care equipment. But understanding how the team and equipment improve health may help you feel more at ease. Also important is learning about treatment options, which may help you make decisions about care.
