MATCH THE ARDS PHASES.

<p>PHASE 1 AND 2 = injury reduces blood flow to the lungs. Platelets aggregate and release histamine (H), Serotonin (S) and Bradykinin (B) THEN NEXT PHASE those substances, especially histamine, inflame and damage the alveolar-capillary membrane, increasing capillary permeability. Fluids then shift into the interstital space. PHASE 3 AND 4 = As capillary permeability increases, proteins and fluids leak out, increasing interstital osmotic pressure and causing pulmonary edema. THEN THE NEXT PHASE. is decreased blood flow and fluids in the alveoli damage surfactant and impair the cell's ability to produce more. As a result, the alveoli collapse, impeding gas exchange and decreasing lung compliance. PHASE 5 = Sufficient Oxygen can't cross the alveolar capillary junction, but carbon dioxide (CO2 ) can and is lost with every exhalation. Oxygen (CO2) and CO2 levels start to decrease in the blood. PHASE 6 = Pulmonary edema worsens, inflammation leads to fibrosis, and gas exchange is further impeded.</p> Signup and view all the answers
