Feeble spontaneous breathing may still be salvageable. Weak spontaneous breathing should be to the point of respiratory failure (very poor respiration), which can be characterized by symptoms such as dyspnea, hypoxia, altered mental status, coma, increased heart rate, and elevated blood pressure, and can be life-threatening in severe cases. The etiology of weak spontaneous breathing may be related to airway obstruction, including any disease that can cause narrowing of the airways, such as tracheo-bronchial inflammation, tumors, scarring, spasm, etc., or it may be related to lesions of the lungs themselves, such as pneumonia, pulmonary edema, silicosis, tuberculosis, emphysema, etc. In addition, heart disease, pulmonary vascular disease, thoracic trauma, neuromuscular lesions, cerebrovascular disease, and sedative-hypnotic drug poisoning can inhibit the respiratory center; myasthenia gravis, severe hypokalemia, organophosphorus poisoning and other diseases can involve the respiratory muscles; all of the above diseases cause the respiratory muscle weakness, paralysis, which caused the weak respiration. Therefore, it is closely related to the patient’s own conditions and etiology to say that there is still a way to save the patient’s weak spontaneous breathing. If the patient’s underlying disease is serious, the onset of the disease is rapid, the symptoms are serious, the cause of the disease is difficult to remove, which may lead to rapid death, if the patient’s underlying disease is mild, and after timely rescue, the prognosis may be good, there is a possibility of cure.
