Respiratory failure
Is respiratory failure reversible?
Respiratory failure has a high mortality rate and can easily lead to the impairment of multiple organ functions, seriously endangering the life of the patient. The mortality rate largely depends on whether the condition can be diagnosed and treated early. In cases of respiratory failure, if the progression is rapid and the body does not have particularly good metabolism, it can easily affect life. Acute respiratory failure is generally curable; it often occurs because carbon dioxide retention leads to hypoxia in the body. At this time, providing high-flow oxygen can effectively alleviate the symptoms and additional appropriate medication can be administered based on the condition to facilitate a return to normal. However, chronic respiratory failure caused by conditions like chronic bronchitis and pulmonary heart disease are major causes of respiratory failure. In such cases, it is only possible to slow the progression of the disease; returning to a normal state is rather unlikely. Therefore, patients with chronic respiratory failure generally need long-term home oxygen therapy to ensure that the hypoxic condition can be improved.
Respiratory Failure Nursing Care Plan
For patients with respiratory failure, treatment is one aspect, and nursing is equally important. A nursing plan should be developed in advance, starting with keeping the airway clear to avoid aspiration of liquids or food into the trachea. It is necessary to frequently help the patient turn and pat their back to facilitate the expulsion of phlegm, while also enhancing nutrition and increasing the intake of various nutrients. During the remission period of respiratory failure, persist in exercising, performing exercises like knee protections to strengthen the activity of the respiratory muscles. Adapt clothing according to seasonal and climatic changes to avoid catching a cold. In nursing, it is important to maintain vital signs, pay attention to the care of the skin and oral mucosa, promptly clear phlegm, and avoid factors that trigger breathing difficulties, such as the stimulation from cold wind and cold air. Maintain regular life patterns, engage in appropriate physical exercise, and prevent the occurrence of colds.
How to rescue respiratory failure
Respiratory failure is a very serious condition clinically, and if not handled promptly, many patients may have their lives endangered. The emergency measures for respiratory failure include the following. First, it is necessary to maintain the patency of the airway. If the patient is unconscious, the patient should be placed in a supine position with the head tilted back, the lower jaw lifted, and the mouth opened to clear the airway of secretions and foreign objects. If this is insufficient, tracheal intubation and other methods should be considered to maintain airway patency. Additionally, oxygen therapy, which involves inhaling oxygen, can correct the patient's hypoxic state. If the respiratory function is very poor, consideration should also be given to using a ventilator to assist breathing. Other emergency measures include etiological treatment, supportive treatment, and protecting the function of other vital organs, among others.
Clinical manifestations of respiratory failure
Respiratory failure is one of the common critical illnesses. So, what are the clinical manifestations of respiratory failure? Firstly, there is difficulty breathing, which is the most common symptom of respiratory failure. Most patients experience noticeable difficulty breathing, and in severe cases, patients may sit upright to breathe, sweat profusely, and appear very distressed. Another symptom is cyanosis, a typical sign of oxygen deficiency. Mild cases may show cyanosis at the extremities and lips, while severe cases can exhibit cyanosis throughout the body. Additional symptoms can include neurological and psychological symptoms such as confusion, mania, convulsions, coma, and drowsiness. Due to the oxygen deficiency affecting various systems, other systems may also show corresponding symptoms, such as tachycardia and arrhythmia in the circulatory system, and potential upper gastrointestinal bleeding in the digestive system.
Is asthma considered respiratory failure?
Asthma and respiratory failure are two distinct concepts. Asthma is a disease, whereas respiratory failure is a clinical outcome resulting from a series of diseases. During an acute asthma attack, there is also a possibility of respiratory failure occurring, and in severe cases, it can lead to serious respiratory failure requiring interventions like tracheal intubation and mechanical ventilation. Therefore, acute asthma attacks require active intervention. Treatments often include nebulized inhalation of short-acting bronchodilators and even intravenous administration of corticosteroids to handle the acute episode. Short-term intravenous use of corticosteroids can also help in controlling the acute attack.
Precursors of respiratory failure
Respiratory failure can be a very acute condition, or it may evolve gradually due to chronic diseases. The basic precursors of respiratory failure generally include hypoxia or hypercapnia. In the early stages of hypoxia, patients may experience excitement or irritability, characterized by rapid breathing and possibly sweating due to the effort of breathing. Symptoms include accelerated breathing and hypoxia; the patient’s lips may also turn blue. If the level of carbon dioxide increases, once past the initial period of excitement and as the hypoxia worsens, the person may become listless. Gradually, their consciousness may become unclear, manifesting as drowsiness or possibly even coma.
Causes of CO2 retention in respiratory failure
Respiratory failure manifests as hypoxia and the retention of carbon dioxide. The main cause of carbon dioxide retention is pathological changes in the respiratory system, such as chronic obstructive pulmonary disease with respiratory failure, status asthmaticus, pulmonary heart disease, lung cancer, etc. Some neuropathies that cause paralysis of the respiratory muscles can lead to respiratory dysfunction, resulting in the retention of carbon dioxide in the body, affecting normal cellular metabolism, causing disturbances in acid-base balance and nervous system function, and posing life-threatening conditions. The most important pathogenic mechanism causing carbon dioxide retention in these diseases is still inadequate alveolar ventilation.
Can people with respiratory failure exercise?
Whether people with respiratory failure can exercise depends mainly on whether the respiratory failure occurred acutely or chronically. Generally, it is usually advised against exercising during acute respiratory failure, such as severe pulmonary inflammation, drowning, or failure of the nervous system functions. Exercise during this time can worsen the body's oxygen deficit and increase oxygen consumption, potentially exacerbating the symptoms of the disease. However, for chronic respiratory failure, such as chronic obstructive pulmonary disease (COPD) or chronic pulmonary interstitial fibrosis, patients have long been enduring hypoxia or hypercapnia. These individuals can engage in appropriate respiratory rehabilitation exercises, such as respiratory rehabilitation gymnastics and some traditional Chinese medicine practices, which can greatly aid in the recovery from the disease, particularly respiratory failure. The decision primarily depends on the patient’s specific condition and their physical tolerance.
Causes of Respiratory Failure
Respiratory failure is relatively common in clinical practice and is frequently seen in critical respiratory conditions. The causes of respiratory failure most often arise from diseases of the respiratory and circulatory systems, such as chronic obstructive pulmonary disease, acute exacerbation of asthma, severe pneumonia, severe pulmonary tuberculosis, diffuse pulmonary fibrosis, pulmonary edema, pneumoconiosis, pulmonary embolism, various causes of heart failure, pulmonary hypertension, severe pneumothorax, and substantial pleural effusion, among others. These can all lead to respiratory failure. Therefore, if respiratory distress occurs clinically and respiratory failure is suspected, it is crucial to conduct prompt examinations and actively manage the condition.
Treatment principles for respiratory failure
Respiratory failure is a common emergency condition in the respiratory system, with patients often experiencing significant breathing difficulties, cyanosis, etc. So, what are the principles of treatment for respiratory failure? The overall principles of treatment are to enhance respiratory support, including maintaining airway patency, correcting hypoxia through oxygen therapy, and improving ventilation with the use of ventilators, among other measures. Additionally, it is important to intensify treatment of the causes and inducers of respiratory failure, such as controlling infections. Attention should also be paid to general supportive treatment, such as nutritional support, correcting electrolyte imbalances, etc., as well as protecting other vital organs, like the liver and kidneys.
