Intensive Care Units

Mercy Hospital St. Louis has four intensive care units, located on the 4th floor of the main hospital, staffed by highly-trained critical care physicians and trauma surgeons who care for our critical care patients, usually following admission through our Emergency Department. We have one 16-bed trauma-neuro ICU and three 12-bed medical surgical ICU rooms. In addition, we have a 12-bed burn unit on the 5th floor of the Mercy Children’s Hospital tower and a 36-bed transitional care unit (TCU) on the 4th floor. All ICU beds are in private rooms.

Our ICUs can be reached at the following unit phone numbers:

The Mercy Heart and Vascular Hospital has two cardiovascular ICUs: the 16-bed cardiovascular intensive care unit (CVICU), dedicated to the care of critically ill patients with cardiac and-or vascular involvement and the 16-bed surgical progressive care unit (SPCU) that specializes in the care of post-operative cardiac and vascular surgery patients.

ICU Resources

While your loved one is a patient in a Mercy Hospital St. Louis Intensive Care Unit (ICU), you can expect the best care possible for him or her. This page is your resource about where to find things you might need while you’re visiting here. If you have questions, please ask us. We want to help.

We know this can be a stressful time for families. This makes communication even more important. We’ve found it helps for family members to choose a family spokesperson to receive daily updates from ICU physicians, ask questions and communicate concerns for your family.

ICU Staffing

Each ICU is staffed by two teams:

  • Primary daytime team: present from 6 a.m. until 5 p.m. This group sets the daily plan, writes daily orders and cares for patients during these hours. They’re most involved in the day-to-day medical treatment of your loved one. A member of this team is responsible for updating you daily.
  • Night team: manages patient care from 5 p.m. until the primary team returns at 6 a.m. The night team continues care, handles emergencies that arise and admits new patients.

It takes many health care professionals to provide the level of care needed by critically ill patients. While each team member has a specific job, they all work together to meet the needs of our patients and families.

Additional ICU medical providers you may encounter include:

  • Attending physician: Physician in charge. Attending physicians are board-certified physicians who have completed training in critical care medicine. Some have additional training in pulmonary or neuro-critical care.
  • Trauma physician: Physician in charge for a trauma patient. Board-certified critical care physicians and surgeons who have specialized in the care of trauma patients
  • ICU nurse: Specializes in caring for intensive care patients.
  • Nurse practitioners/physician assistants: Practice medicine under the supervision of a collaborative physician and report to them. They help admit and manage the care of ICU patients.

Mercy Hospital St. Louis is a Teaching Hospital

This means some members of the critical care team are learning their jobs under the careful supervision of our experienced physician teachers.

  • Fellow: A board-certified physician in training to become a critical care specialist.
  • Resident: A physician who practices medicine under the attending physician’s and fellow’s supervision.
  • Graduate nurses/student nurses doing clinical rotations in our ICU: Nurses who have graduated from nursing school and are training to become ICU nurses. Both are under direct supervision of the board-certified ICU RNs.
