Intensive Care Unit (ICU) patients are individuals who require close monitoring and specialized medical care due to critical illness or injury. These patients are typically admitted to the ICU for conditions such as severe infections, organ failure, trauma, or after major surgical procedures. ICU patients often require advanced medical interventions such as mechanical ventilation, vasopressor medications, and continuous hemodynamic monitoring. The primary goals of ICU care are to stabilize the patient's condition, prevent further complications, and support organ function until they are able to recover. Research in this area focuses on improving outcomes for ICU patients, identifying effective treatment strategies, and enhancing the overall quality of care in the ICU setting.
