Respiratory failure refers to the severe impairment of lung ventilation and gas exchange function caused by various reasons. The treatment of respiratory failure is comprehensive. Firstly, it is necessary to maintain the patency of the airway. Second, oxygen therapy is required. Oxygen therapy is mainly used to correct the patient's hypoxia. Third, a ventilator can be used to assist breathing. Fourth, the cause of the condition should be addressed. For example, if it is caused by a severe infection, aggressive anti-infection measures should be taken; if caused by a large amount of pleural effusion, aggressive drainage of the pleural fluid should be undertaken, etc. Additionally, general supportive therapy should be considered, such as maintaining electrolyte and acid-base balance. It is also important to protect the function of vital organs, such as maintaining the function of the heart and lungs, etc.

Is respiratory failure contagious?

First, it's important to understand what respiratory failure is. Respiratory failure is a syndrome, not a disease, meaning it can result from many causes. For instance, airway obstruction, lung tissue pathology, diseases of the pulmonary vessels, and diseases of the thorax and pleura, as well as neuromuscular diseases, can all lead to impaired ventilation or gas exchange in the lungs. This impairment makes it impossible for the body to maintain adequate gas exchange even in a resting state, resulting in hypoxemia, with or without hypercapnia, which is referred to as respiratory failure. Therefore, there are many causes of respiratory failure, and some diseases are indeed contagious, such as SARS, H1N1, and H3N2. However, other causes, such as tumors or pulmonary embolism, are generally not contagious.

Is respiratory failure uncomfortable?

Respiratory failure is quite uncomfortable, and clinically, the symptoms feel severe, and the patient's own state is also very affected. Respiratory failure is mainly caused by a decrease in oxygen partial pressure, during which time the patient may experience wheezing, chest tightness, and even a feeling of being near death. There are many causes of respiratory failure, with severe infections being common, such as severe pneumonia or sepsis. A systemic inflammatory response can lead to respiratory failure. Another situation is when heart failure occurs, which can also accompany pulmonary congestion, causing pulmonary ventilation dysfunction that can also lead to respiratory failure. The treatment of respiratory failure focuses on removing the causative factors and selectively choosing different treatment plans, which can start with oxygen therapy or the use of a ventilator in severe cases to correct hypoxemia and sustain life.

What are the symptoms of respiratory failure?

Respiratory failure is a common critical illness in clinical settings, characterized by serious impairments in the lung's ventilation and gas exchange functions. What are the symptoms after respiratory failure? First and foremost, the earliest and most obvious symptom is difficulty breathing. Many patients experience significant difficulty breathing; severe cases may even involve orthopnea, profuse sweating, and inability to speak. Another important symptom is cyanosis, which is a typical manifestation of hypoxia. Additionally, there can be neuropsychiatric symptoms such as mental confusion, agitation, convulsions, and even coma. Other systems may also exhibit symptoms, such as tachycardia, arrhythmias, and decreased gastrointestinal function.

What are the symptoms of respiratory failure?

Respiratory failure is a common and serious condition in clinical settings, often categorized as an acute and critical illness. Simply put, respiratory failure occurs when respiratory function is extremely poor. It is caused by severe impairment of pulmonary ventilation and gas exchange due to various reasons. Even at rest, sufficient gas exchange cannot be maintained, leading to serious hypoxemia or concurrent hypercapnia. Clinically, this often presents with severe breathing difficulties, hypoxia, cyanosis, and requires immediate intervention to prevent potentially life-threatening complications.

Respiratory failure classified by etiology

Respiratory failure can be classified according to its causes into four types. The first type involves diseases of the airway such as bronchial inflammation, bronchiectasis, and foreign body obstruction, leading to insufficient ventilation. The second type is due to lung tissue diseases, such as pneumonia, severe tuberculosis, emphysema, diffuse pulmonary fibrosis, adult respiratory distress syndrome, etc., causing a state of hypoxia and carbon dioxide retention due to ventilatory defects. The third type includes pulmonary vascular diseases, such as pulmonary vascular embolism and pulmonary infarction, which cause part of the venous blood to flow into the pulmonary veins, resulting in hypoxia. The fourth type involves diseases of the thoracic cage such as chest trauma, surgical trauma, pneumothorax, and pleural effusion, which affect daily activities and lung expansion, leading to insufficient lung ventilation and resulting in respiratory failure.
