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.

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.

How to grade respiratory failure

Respiratory failure is generally not graded; instead, it is classified into types. There are two types, Type I and Type II. Type I is characterized by an oxygen tension lower than 60 mmHg, at which point, there is no increase in carbon dioxide, and the carbon dioxide level is normal. Type II respiratory failure is when the oxygen tension is below 60 mmHg, accompanied by an increase in carbon dioxide, which is then termed Type II respiratory failure. Regarding respiratory failure, it is classified by type and not by severity grade. This means that once it meets these criteria, it is referred to as respiratory failure, and at this point, some emergency treatments to improve low oxygen levels are necessary. Therefore, respiratory failure is generally not graded into mild, moderate, or severe degrees. It is only differentiated into different types. Of course, there are different severity levels in respiratory failure, but we generally do not apply a specific degree of severity.

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.

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.
