Signs and Symptoms of Respiratory Diseases can include: Pleural Pain, Friction Rub, Cyanosis, and Chronic Hypoxia<\/strong><\/h2>\r\n

Pleural Pain and Inflammation:<\/strong><\/h1>\r\n
    \r\n \t
  • Pleural membranes:<\/strong>\u00a0Visceral and parietal pleura surround each lung, separated by the pleural cavity filled with serous fluid.<\/li>\r\n \t
  • Pleural pain:<\/strong>\u00a0Caused by infection, trauma, or inflammation that irritates or damages these membranes, leading to rubbing and discomfort, especially during breathing or coughing.<\/li>\r\n \t
  • Exudate:<\/strong>\u00a0Fluid buildup in the pleural space may occur, often requiring aspiration for diagnosis and treatment.<\/li>\r\n \t
  • Friction rub:<\/strong>\u00a0A sound heard via stethoscope indicating inflamed pleural membranes rubbing against each other.<\/li>\r\n<\/ul>\r\n

    Cyanosis and Chronic Hypoxia:<\/strong><\/h1>\r\n
      \r\n \t
    • Cyanosis,<\/strong> particularly in fingers and toes, indicates prolonged hypoxia.<\/li>\r\n \t
    • Remodeling:<\/strong>\u00a0Long-term hypoxia causes fibrosis (scarring), leading to finger clubbing.<\/li>\r\n \t
    • Arterial blood gases (ABGs):<\/strong>\r\n
        \r\n \t
      • Hypoxemia:<\/strong>\u00a0Low oxygen in blood.<\/li>\r\n \t
      • Hypercapnia:<\/strong>\u00a0Excess carbon dioxide in blood.<\/li>\r\n \t
      • Hypoxia:<\/strong>\u00a0Insufficient oxygen delivery to tissues.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t
      • Blood gas abnormalities may result from lung issues, red blood cell problems (anemia, hemoglobin deficiency), or heart issues affecting blood oxygenation.<\/li>\r\n<\/ul>\r\n

        Poisonous Causes and Risks of Impaired Gas Exchange:<\/strong><\/h1>\r\n
