Care in the ICU differs from other hospital units.
Seriously ill patients require close observation and monitoring. Specially trained nurses care for one or two patients at a time, each shift. ICU doctors are specially trained critical care doctors.
Patients may have special equipment in their room, depending on their unique situation and condition. The equipment in the ICU may seem overwhelming. Patients are connected to machines to monitor their heart, blood pressure, and respiratory rate. Ventilators (breathing machines) assist some patients with breathing until they are able to breathe on their own.
