Why acute respiratory failure?

summary

For the situation of respiratory failure is a very serious phenomenon, of course, everyone's condition is different, some patients belong to the phenomenon of acute respiratory failure, once there is respiratory failure, patients will have physiological function and metabolic disorders, we must find out the cause and then do targeted treatment, why will there be acute respiratory failure? Let's talk about it

Why acute respiratory failure?

Bronchitis, bronchospasm, foreign bodies and other obstructed airways cause inadequate ventilation, uneven gas distribution, * imbalance of ventilation / blood flow, hypoxia and carbon dioxide retention. Pulmonary embolism, pulmonary infarction, so that part of the venous blood into the pulmonary vein, hypoxia.

Pneumonia, severe pulmonary tuberculosis, emphysema, diffuse pulmonary fibrosis, adult respiratory distress syndrome (ARDS), etc. can cause lung volume, ventilation, effective dispersion area, and * ventilation / blood flow imbalance leading to pulmonary artery shunt, causing hypoxia and / or carbon dioxide retention.

Such as thoracic trauma, surgical trauma, pneumothorax and pleural effusion, affect the thoracic activity and lung expansion, lead to reduced ventilation, uneven inhalation of gas, affect the ventilation function. Cerebrovascular diseases, encephalitis, brain trauma, drug poisoning directly or indirectly inhibit the respiratory center; Neuromuscular junction block caused by poliomyelitis and polyneuritis affects conduction function; Myasthenia gravis and other respiratory damage caused by insufficient ventilation.

matters needing attention

Relieve bronchospasm, eliminate bronchial mucosal edema, reduce bronchial secretions, reduce airway resistance, reduce energy consumption. Enhance nutrition, improve the intake of sugar, protein and various vitamins, if necessary, intravenous infusion of compound amino drum, plasma, albumin.
