The treatment of acute respiratory failure may involve medication such as bronchodilators (for airways disease), [7] [8] antibiotics (for infections), glucocorticoids (for numerous causes), diuretics (for pulmonary oedema), amongst others. [1] [9] [10] Respiratory failure resulting from an overdose of opioids may be treated with the antidote ...
The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

The most common causes of dyspnea are cardiac (cardiac asthma) [10] and pulmonary conditions, like congestive heart failure with preserved ejection fraction, COPD, or pneumonia. [9] Less commonly, some cases of dyspnea can be attributed to neuromuscular diseases of the chest wall or anxiety.
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2] Hypoxemia is usually caused by pulmonary disease whereas tissue oxygenation requires additionally adequate circulation of blood and perfusion of tissue to meet metabolic demands. [4]
Patients in acute care hospitals, particularly those with respiratory conditions, are at risk for developing respiratory compromise. Respiratory failure requiring emergency mechanical ventilation occurs in over 40,000 patients per year in the United States. [2]
To be classified as pulmonary heart disease, the cause must originate in the pulmonary circulation system; RVH due to a systemic defect is not classified as pulmonary heart disease. Two causes are vascular changes as a result of tissue damage (e.g. disease, hypoxic injury), and chronic hypoxic pulmonary vasoconstriction. If left untreated, then ...
The body has different ways of coping with acute hypoxia. Mammals that rely on pulmonary ventilation will increase their ventilation to account for the lack of oxygen reaching the tissues. [ 2 ] Mammals will also experience decreases in aerobic metabolism and oxygen demand, along with increases in ATP production.
