Value of Pa02/ Fi02 chracteristic of ARDS is
Answer- A. < 200 mmHgAcute respiratory distress syndrome (ARDS) is a clinical symdrome of severe dyspnea of rapid onset, hypoxemia, and diffirse pulmonary infiltrates leading to respiratory failure.The aerial PaO, (in mmHg)/FiO, (inspiratory O, fraction) <200 mmHg is characteristic of ARDS, while a PaO, /FiO, between 200 and 300 identifies patients with ALI who are likely to benefit from aggressive therapy.
