Two teams staff each ICU:

  • 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 to care, handles emergencies that arise and admits new patients.

It takes many healthcare professionals to provide the care critically ill patients need. 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: a 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: a physician in charge of 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.

This means some critical care team members 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 are trained to become ICU nurses. Both are under the direct supervision of the board-certified ICU RNs.

A team of additional caregivers may also care for your loved one. They include:

  • Respiratory therapists: Healthcare professionals who treat, evaluate, and monitor patients with breathing problems. They assist with mechanical ventilation and with following management and weaning protocols.
  • Wound and ostomy nurse: A registered nurse who has additional training in how to care for people who have a wound, an ostomy (an opening made by surgery from an area inside the body to the outside), or problems with continence (ability to control the flow of urine or the passage of stool).
  • Physical therapists: Healthcare professionals trained to maximize patients’ strength and mobility.
