Acute respiratory distress syndrome Symptoms

Clinical manifestation of ARDS is respiratory distress, progressive hypoxemia, diffuse lung injury, increased pulmonary microvascular permeability and alveolar atrophy.

In addition to corresponding with the onset of symptoms, when lung damage has just a few hours, the patient with ARDS have no respiratory symptoms. Followed by respiratory rate accelerated gradually increase shortness of breath, no abnormal signs were found in the lungs.

X-ray showed clear lungs, increased lung markings, or only vague, suggesting that fluid accumulation around blood vessels. Arterial blood gas analysis showed PaO2 and low PaCO2.

As the disease progress, occur symptoms include respiratory distress, chest contracting, inspiratory dyspnea, cyanosis, irritability, anxiety, extensive stromal invasion of lungs, may be associated with the expansion of azygos vein, a small amount of pleural effusion or reaction. Hypoxemia as a result of obvious cause hyperventilation, PaCO2 lower respiratory alkalosis. Respiratory distress usually can not be used to improve the oxygen therapy.

If the condition continues to deteriorate, respiratory distress and cyanosis continued to grow, chest X-ray showed pulmonary infiltration in former times large areas of negative integration. Respiratory muscle fatigue leading to inadequate ventilation, carbon dioxide retention, resulting in mixed acidosis. Cardiac arrest. Some patients with Acute respiratory distress syndrome have Symptoms include multiple organ failure.
