Respiratory failure is a condition characterized by significant decline in respiratory function and is clinically very serious, being a common critical and acute illness. Respiratory failure itself is not contagious, but certain diseases that cause respiratory failure can be contagious. For example, if it is caused by infectious pulmonary tuberculosis, then the tuberculosis can be transmitted, but respiratory failure itself is not contagious.

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.

How to treat respiratory failure?

Treatment of patients with respiratory failure is primarily medical, focusing on suppressing or relieving the causes and triggers of respiratory failure, improving lung ventilation and gas exchange as much as possible, and treating and improving the function and condition of various vital organs. First, it is important to actively treat the primary disease causing respiratory failure. If there is a concurrent bacterial infection, sensitive antibiotics should be used, and triggers should be removed as much as possible. Simultaneously, maintaining airway patency and effective ventilation volume is necessary, which can involve administering bronchodilators and expectorants such as salbutamol, terbutaline sulfate, acetylcysteine, and ambroxol. When necessary, corticosteroids can be administered intravenously. If internal medicine treatment does not improve symptoms, tracheotomy and mechanical ventilation may be necessary to assist breathing. (Medications should be taken under the guidance of a physician, based on the actual situation.)

Respiratory failure is a disease.

Respiratory failure is a condition caused by severe impairment of lung ventilation and gas exchange functions due to various reasons, leading to ineffective gas exchange. This results in hypoxia in the body, accompanied by either retention or non-retention of carbon dioxide, thereby causing a clinical syndrome of physiological and metabolic disorders. The causes of respiratory failure include diseases of the lung tissue, respiratory tract disorders, pulmonary vascular diseases, and cardiovascular and cerebrovascular diseases, among other factors, all of which can lead to respiratory failure.

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.

Care of Patients with Respiratory Failure

In the nursing care of patients with respiratory failure, it is important to strictly monitor vital signs daily, as respiratory failure is considered an emergency and critical condition clinically. Observe the patient's blood pressure, consciousness state, and respiratory rate. At the same time, good skin care and oral care should be maintained to prevent aspiration pneumonia and bedsores. Most importantly, secretions should be cleared in a timely manner, including phlegm. Conscious patients should be encouraged to cough forcefully. For patients who are weak in coughing, assist them in turning and patting their backs regularly to facilitate the expulsion of phlegm. For comatose patients, mechanical suction can be used to maintain airway patency. It is advisable to avoid factors that may cause breathing difficulties, such as cold wind and poor air circulation. Pay attention to enhancing physical exercise appropriately, preventing colds, and maintaining a regular lifestyle.
