However, they can increase the risk of tissue ischemia, arrhythmias, and organ damage if not closely monitored. Discuss the principles of managing acute respiratory distress syndrome (ARDS) in critical care nursing. Management of ARDS involves low tidal volume ventilation, positive end-expiratory pressure (PEEP), and proning to improve oxygenation. The goal is to minimize ventilator-induced lung injury and maintain oxygen delivery while preventing further damage to the lungs. What are the physiological mechanisms underlying cardiogenic shock, and how is it treated in the critical care setting? Cardiogenic shock results from the heart's inability to pump blood effectively, leading to decreased perfusion and tissue hypoxia. Treatment includes the use of inotropes, vasopressors, and mechanical support devices such as intra-aortic balloon pumps (IABP) to improve cardiac output. Explain the role of nutrition in the management of critically ill patients and the differences between enteral and parenteral feeding. Enteral feeding is preferred for critically ill patients as it helps maintain gut integrity and reduces the risk of infection. Parenteral nutrition is used when enteral feeding is not feasible, but it carries higher risks of infection and metabolic complications. What is the significance of the nursing assessment of fluid balance in critically ill patients? Monitoring fluid balance is crucial in preventing both dehydration and fluid overload. Accurate assessment involves tracking intake, output, weight changes, and physical signs such as edema to guide appropriate interventions. Define the term "multisystem organ failure" and its relevance to critical care nursing. 6 7 Multisystem organ failure refers to the progressive dysfunction of two or more organ systems, often seen in sepsis, trauma, or prolonged shock.
