Intensive care usually takes a system by system approach to treatment, rather than the SOAP (subjective, objective, analysis, plan) approach of high dependency care. The nine key systems (see below) are each considered on an observation-intervention-impression basis to produce a daily plan. As well as the key systems, intensive care treatment raises other issues including psychological health, pressure points, mobilisation and physiotherapy, and secondary infections. The nine key IC systems are: cardiovascular system, central nervous system, endocrine system, gastro-intestinal tract (and nutritional condition), haematology, microbiology (including sepsis status), peripheries (and skin), renal (and metabolic), and respiratory system. Intensive care is usually provided in a specialized unit of a hospital called the intensive care unit (ICU) or critical care unit (CCU). Many hospitals also have designated intensive care areas for certain specialities of medicine, such as the coronary intensive care unit (CCU or sometimes CICU) for heart disease, medical intensive care unit (MICU), surgical intensive care unit (SICU), Pediatric intensive care unit (PICU), neuroscience critical care unit (NCCU), overnight intensive-recovery (OIR), shock/trauma intensive-care unit (STICU), neonatal intensive care unit (NICU), and other units as dictated by the needs and available resources of each hospital.
