Patients may be intubated, on ventilators, or connected to various life-support systems. The unit ensures around-the-clock care with dedicated nurses and physicians, emphasizing rapid response to changing clinical situations (Washington State Department of Health, 2022). For example, ventilated patients are closely monitored to prevent complications and stabilize their condition.
Labour and Delivery (L&D) Unit:
Women in active labor or at imminent risk of delivery are admitted here. This unit provides the environment for childbirth, whether vaginal or cesarean. After delivery, both mother and infant are monitored until stable, typically staying for one or two days. The unit is focused solely on labor and immediate postpartum care, not early pregnancy or fertility issues.
Medicine Unit:
This versatile department manages a broad range of illnesses that don’t require highly specialized interventions. Common conditions include pneumonia, bronchitis, or mobility issues, as well as patients awaiting transfer to long-term care facilities. It often serves as a general inpatient ward for patients with multiple concurrent health problems, emphasizing medical stabilization and symptom management.
Nephrology Unit:
Patients with kidney-related issues, including kidney stones, obstructions, or chronic kidney disease, are treated here. Dialysis is frequently performed either within this unit or the dedicated dialysis facilities. The team provides both acute and ongoing care to manage renal function and related complications.
Neurology Unit:
This unit cares for patients with nervous system disorders such as strokes, traumatic brain injuries, epilepsy, or neuromuscular diseases. Patients often require post-acute management or rehabilitation, with treatments tailored to neurological recovery and ongoing management of chronic neurological conditions.
Neonatal Intensive Care Unit (NICU):
Specialized for newborns requiring intensive monitoring and life support, the NICU cares for premature infants, critically ill newborns, or those with congenital conditions. Advanced equipment and specialized staff, including neonatologists, ensure optimal care during these vulnerable early days (see Fig. 9.17). The NICU plays a vital role in neonatal survival and development.
Oncology Unit:
Patients diagnosed with various types of cancer are treated in this specialized department. The unit offers chemotherapy, radiation therapy, and supportive care aimed at managing symptoms and progressing treatment plans as part of comprehensive cancer care.
