Critical Care Units (MSICU, NICU, Intermediate Care)

About Critical Care

Greenwich  Hospital's critical care units treat patients who need complex, specialized care and constant monitoring. Patients and their families benefit from an extensive range of skilled specialists led by the unit's medical director, a board-certified critical care specialist (intensivist).  

The critical care team includes neurologists, cardiologists, orthopedists and pulmonologists, as well as nurses,  pharmacists, respiratory therapists, dietitians, speech, physical and occupational therapists, clergy, social workers and case managers.

We continuously implement the highest standards of care, including best practices in key areas such as cardiac and stroke care, and infection control.

Greenwich Hospital’s Medical-Surgical Intensive Care Unit (MSICU) provides specialized treatment and monitoring of critically ill patients. In addition, our Intermediate Care Unit, sometimes called “Telemetry,” provides special monitoring and nursing for patients who no longer require intensive care.  The hospital also has a Neonatal Intensive Care Unit (NICU) for babies with critical needs.

Support for Patients and Families
Critical care units can be overwhelming and stressful.  Our staff is here to listen to the concerns of patients and families and answer questions. Social workers and spiritual counselors are also available.

Medical-Surgical Intensive Care Unit (MSICU)
This 10-bed intensive care unit  is equipped to provide the safest and most advanced intensive care. Technology ranges from sophisticated bedside monitors to leading-edge ventilators and defibrillators. Staff are specially trained to treat patients with complex and life-threatening conditions.

The MSICU has a comfortable lounge for families as well as private consulting areas for conferences with medical staff.  An information center in the hospital’s medical library provides patients and families with access to medical information. Overnight accommodations can be made for family members in the lounge or the patient's room.
The MSICU treats children and adults. (Babies receive care in our Neonatal Intensive Care Unit.) Pediatric patients requiring longer term intensive care are generally stabilized at Greenwich Hospital and then transferred to our affiliate, Yale New Haven Hospital.

  • Visiting hours are flexible to meet the needs of patients and their families. We ask close family and friends to refrain from visiting during shift changes (7-8am and 7-8pm).  
Intermediate Care Unit
Our 20-bed Intermediate Care Unit is for patients with cardiac or other medical conditions that do not need intensive care, but do require specialized monitoring, nursing and resources.

This unit features advanced sensing devices that allow staff to continuously monitor a patient’s heart rhythms and respiration from a central location. (Sometimes the Intermediate Care Unit is referred to by the name of this technology: telemetry.) The staff includes specially trained registered nurses, cardiac monitor technicians and nursing assistants.
