Normal people do breathe on their own, which is a physiological manifestation of normal respiratory function. In case of forgetting to breathe, this condition requires consideration of some pathological states and needs to be treated accordingly. For example, it is common to have respiratory distress, respiratory failure, pneumothorax or fluid pneumothorax due to severe lung infections, and trauma to the lungs. At this time, for inflammation, sensitive anti-inflammatory drugs can be given to reduce the congestion and edema of the lung mucosa, such as bacterial infections can choose to use sensitive antibiotics, such as ceftriaxone, cefoperazone, clindamycin, roxithromycin, levofloxacin and other drugs. For pneumothorax, closed drainage of the chest cavity should be performed promptly to normalize the compressed lung. In severe cases, mechanical ventilation may be required, and a ventilator may be needed to restore respiration. After the patient’s vital signs stabilize, the ventilator can be gradually withdrawn to gradually restore the state of spontaneous breathing.
