Adult respiratory distress syndrome. A complication of shock

ARDS is a complex type of respiratory failure that usually is a complication of a catastrophic critical illness, such as shock. Mortality is high, especially in patients with septic shock and multisystem failure. Mortality often is related to complications of refractory hypoxemia. Identifying patients at risk for developing ARDS and early recognition of ARDS are important so that treatment can be initiated to prevent the potentially lethal consequences of refractory hypoxemia. The nurse has an important role in collaborating with the physician and respiratory therapist to support the patient's oxygenation, ventilation, and tissue oxygen delivery system. The nurse is responsible for performing highly sophisticated assessment of clinical and hemodynamic parameters to evaluate the effectiveness of therapy. A key role of the nurse is anticipating, recognizing, and reporting to the physician complications of hypoxemia and complications of therapy that can lead to sepsis, airway trauma, or failure of other organ systems.
