Patients with respiratory failure are always emergency and critically ill patients in clinical settings. For patients with respiratory failure, we need to pay close attention in nursing: first, strictly monitor the patient's vital signs, observe the frequency of respiration, blood pressure, and consciousness state; take good care of the skin and oral cavity to prevent dependent pneumonia and bedsores; and timely remove the patient’s sputum. Encourage conscious patients to cough more and expectorate sputum. For those with weak coughs, assist regularly with turning and patting the back to facilitate the removal of sputum. For comatose patients, mechanical suction or tracheostomy for mechanical ventilation can be performed. At the same time, avoid factors that can induce respiratory difficulty such as cold air and poor air circulation. Patients with respiratory failure consume a lot of energy, especially those on mechanical ventilation, who are in a stress state with increased catabolism. Therefore, daily protein intake should be increased, encourage the patient to eat more to enhance nutrition, and provide a diet high in protein, high in fat, and low in carbohydrates.

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.

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.

Can respiratory failure be cured?

Respiratory failure can potentially be cured, and the key lies in identifying the cause of the respiratory failure. For instance, acute inflammatory infections, such as severe pneumonia and other infectious diseases, can lead to dysfunction in lung ventilation and gas exchange, manifesting as respiratory failure. With the aggressive use of antibiotics and anti-infection drugs, once the infection is controlled, respiratory failure can also be corrected accordingly. Furthermore, if it is a complication of other diseases, such as acute left heart failure, respiratory failure can also occur. This type of respiratory failure will quickly improve once heart function is corrected. However, in the case of chronic diseases such as chronic obstructive pulmonary disease, bronchiectasis, asthma, and other causes, respiratory failure can only be managed with medication to alleviate symptoms, and it cannot be completely cured.

Treatment of Respiratory Failure

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.
