What are the manifestations of respiratory acidosis?

summary

Clinical manifestations of respiratory acidosis? The patient has dyspnea, insufficient ventilation, sometimes shortness of breath, cyanosis, headache, chest tightness and general fatigue. With the aggravation of acidosis, the patient may have blood pressure drop, delirium, coma, acute severe acid exhalation is characterized by shortness of breath, dyspnea and obvious neurological symptoms, such as headache, blurred vision, restlessness, even tremor, blurred consciousness, delirium and coma. Physical examination can find optic disc edema, increased pressure of cerebrospinal fluid and arrhythmia. The symptoms of chronic respiratory acidosis are often masked by primary diseases..

What are the manifestations of respiratory acidosis?

When diuretics are used, a large amount of urine is excreted. Long term fluid replacement without potassium is needed. Large amount of potassium is lost, such as vomiting, continuous gastrointestinal decompression and intestinal fistula

The most effective methods are endotracheal intubation and mechanical ventilation. The purpose of treatment is to make pH value return to normal, rather than simply treat PaCO2 abnormality. If the respiratory depression is caused by morphine and other drugs, naloxone can be injected intravenously

The treatment of primary disease is more important than that of primary disease. Mechanical ventilation should be used conservatively.

matters needing attention

Sodium bicarbonate is generally not suitable for use; Acetazolamide should be used with caution. For metabolic acidosis, the most important thing is to identify and deal with the primary disease of acidosis, as well as the water electrolyte imbalance. First of all, to determine whether the metabolic acidosis with increased Ag and which disease caused acidosis, and according to the condition, choose alkaline solution. In the case of lactic acidosis, it is necessary to correct tissue hypoxia or glucose metabolism disorder, so as to reduce the production of lactic acid and promote the oxidation of lactic acid
