How is an intensive care unit different from a regular hospital floor?
Answer
An intensive care unit provides continuous monitoring and a higher nurse-to-patient ratio for people who need close observation or organ support.
Units are often specialized — medical, surgical, cardiac, neurological, or neonatal — and visiting practices vary by hospital.
Key points
- Ask who the attending clinician is and when daily rounds happen.
- Ask for one designated family contact to reduce mixed messages.
- Step-down units provide an intermediate level of monitoring.
