Respiratory failure
Classification of Causes of Respiratory Failure
Respiratory failure, if categorized by its cause, can be divided into pump failure and lung failure. Pump failure refers to the failure of the respiratory pump, which comprises the central nervous system that drives or regulates respiratory movement, the peripheral nervous system, neuromuscular tissues, and the thoracic cage, collectively known as the respiratory pump. Respiratory failure caused by dysfunction of these components is called pump failure. Another type is lung failure, which results from airway obstruction, pulmonary tissue and vascular pathology, and is termed lung failure. Lung failure can lead to type I or type II respiratory failure, whereas pump failure typically presents as type II 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.)
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.
The earliest clinical symptoms of respiratory failure
The clinical symptoms of respiratory failure mainly manifest as hypoxemia and carbon dioxide retention. Looking at their clinical manifestations, mild hypoxia may not show any clinical symptoms. As the severity of the disease increases, there can be signs of increased respiratory drive, such as rapid breathing or difficulty breathing, along with symptoms of sympathetic nervous system activation, such as anxiety and sweating. Hypoxemia can cause dilation of peripheral arteries and constriction of veins, leading to an increased heart rate, or even severe arrhythmias. Furthermore, considering the clinical manifestations of carbon dioxide retention, they are directly related to the levels of carbon dioxide in the body, mainly depending on the rate of occurrence. Clinically, this primarily affects myocardial contractility, the contractile ability of respiratory muscles, and increases in intracranial blood flow. In mild to moderate cases, it can stimulate the respiratory center causing increased and shallow breathing, but in severe cases, it may suppress the respiratory center.
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.
Can respiratory failure be cured?
Respiratory failure is a critical condition in clinical settings, characterized by high mortality rates and the potential to impair multiple organ functions, thus endangering the lives of patients. However, in cases of chronic respiratory failure, it is generally incurable, as the respiratory function of these patients has already declined significantly. For patients with acute respiratory failure, the possibility of recovery is closely tied to the ability to diagnose early and administer effective treatment promptly. If acute respiratory failure is treated effectively early on by removing the trigger and the cause, and if the respiratory function can significantly improve within a short time, then there is still a chance for a cure.
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.
Does respiratory failure spread?
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.
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.
