Information About Respiratory Failure Pathophysiology

This is a popular syndrome in which the system fails in performing in one or both of its functions of the gas exchange. That is carbon dioxide elimination and oxygenation. This can be in practice characterized as either hypercapnic or hypoxemic. Here you will know more about respiratory failure pathophysiology. To learn more about medical terms and to understand the meaning of them, you can visit Dr. plastic surgery Melbourne clinic.

Hypoxemic (type I) is usually characterized by arterial oxygen tension that is normally lower than 60 mm Hg with a low or normal tension of arterial carbon dioxide. Hypoxemic is one of the most common forms of this disorder and it can be associated with withal lung acute diseases that normally involves the collapse of alveolar units and fluid filling. Some of the examples of this (type I) disorder are the noncardiogenic and cardiogenic pulmonary edema, the pulmonary hemorrhage and pneumonia.

respiratory failureHypercapnic (type II) comprises features such as a PaCO2 higher than 50 mm Hg. Patients with hypercapnic (type II) who are breathing room air commonly suffer from Hypoxemia. The pH levels are associated with the level of bicarbonate since they are interdependent. The duration of hypercapnia also depends on bicarbonate levels. Examples of the known etiologies in this (type II) include; neuromuscular disease and drug overdose, abnormalities of the chest wall, and severe disorders of the airway like for instance asthma.

Here are the Causes of Respiratory Failure Pathophysiology

  • Can be brought about by interference with the chest wall mechanics: Obesity, paralysis of the diaphragm and the chest wall muscles, severe kyphoscoliosis, immobility of the chest wall as in progressive systemic sclerosis and flail chest injury that has many rib fractures.
  • Disorders of Pleural: Tension pneumothorax, high amounts of collected pleural fluid and gross thickening of the pleura.
  • Airways diseases: Laryngeal edema, advanced chronic bronchitis, severe asthma, mechanical obstruction of airways and emphysema.
  • Pulmonary diseases: Allergic alveolitis, bilateral pneumonia, pulmonary interstitial fibrosis, adult respiratory distress syndrome, and neonatal and extensive malignancy
  • Respiratory Centre depression: Narcotic poisoning and intracranial tension.
