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.

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.

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.

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.

How to administer oxygen for respiratory failure

If patients with respiratory failure undergo oxygen therapy, it is necessary to choose different therapy plans based on the type of respiratory failure. In the case of Type I respiratory failure, there is simply a lack of oxygen. For Type II respiratory failure, there is not only a lack of oxygen but also an accumulation of carbon dioxide. Therefore, for Type I respiratory failure, the oxygen flow can be higher, over five liters per minute, and the patient can continuously receive oxygen without causing significant side effects. However, for Type II respiratory failure, it is essential to control the oxygen flow at a low rate, under three liters per minute, otherwise, it may lead to other complications.

Can respiratory failure be cured?

Whether respiratory failure can be cured depends on the causes of the respiratory failure and the severity of the condition. Respiratory failure can potentially be cured. For example, acute left heart failure can lead to pulmonary congestion and subsequent respiratory failure. This condition primarily manifests as a decrease in oxygen tension, and by conducting a blood gas analysis, if the oxygen tension is found to be less than 60 mmHg, it can be diagnosed as respiratory failure. However, with symptomatic treatments such as vasodilation and diuretics, once the left heart failure is alleviated, the respiratory failure will also improve. On the other hand, for diseases intrinsic to the lungs, such as chronic obstructive pulmonary disease or severe pulmonary infections, these chronic conditions cannot be completely cured. The symptoms of respiratory failure can only be managed with medication or ventilators.
