Cases of chronic respiratory acidosis may cause memory loss, impaired coordination, polycythemia, pulmonary hypertension, and heart failure. If severe enough, increased intracranial pressure and papilledema may ensue, increasing the risk of herniation and possibly even death. Respiratory acidosis leads to hypercapnia, which induces cerebral vasodilation. If the respiratory acidosis is severe and accompanied by prolonged hypoventilation, the patient may have additional symptoms such as altered mental status, myoclonus, and possibly even seizures. In some cases, patients may present with cyanosis due to hypoxemia. Patients can present with dyspnea, anxiety, wheezing, and sleep disturbances. Signs and symptoms vary based on the length, severity, and progression of the disorder. The clinical presentation of respiratory acidosis is usually a manifestation of its underlying cause. In chronic respiratory acidosis, renal compensation occurs gradually over the course of days. Respiratory acidosis may cause slight elevations in ionized calcium and an extracellular shift of potassium. In patients with chronic compensated respiratory disease and acidosis, an acute insult such as pneumonia or disease exacerbation can lead to ventilation/perfusion mismatch. Chronic respiratory acidosis can also be seen in obesity hypoventilation syndrome, also known as Pickwickian syndrome, amyotrophic lateral sclerosis, and in patients with severe thoracic skeletal defects. Other individuals who develop chronic respiratory acidosis may have fatigue of the diaphragm resulting from a muscular disorder. On the contrary, chronic respiratory acidosis may be caused by COPD where there is a decreased responsiveness of the reflexes to states of hypoxia and hypercapnia. Because of its acute nature, there is a slight compensation occurring minutes after the incidence. This may be due to cerebrovascular accidents, use of central nervous system (CNS) depressants such as opioids, or inability to use muscles of respiration because of disorders like myasthenia gravis, muscular dystrophy or Guillain-Barre Syndrome. Respiratory acidosis can be subcategorized as acute, chronic, or acute and chronic. In acute respiratory acidosis, there is a sudden elevation of PCO2 because of failure of ventilation. Another pathophysiological mechanism may be due to ventilation/perfusion mismatch of dead space. When ventilation is disrupted, arterial PCO2 increases and an acid-base disorder develop. A decreased pH level influences the mechanics of ventilation and maintains proper levels of carbon dioxide and oxygen. Central chemoreceptors in the medulla are sensitive to changes in the pH level. Chemoreceptors for PCO2, PO2, and pH regulate ventilation. There's more to see - the rest of this topic is available only to subscribers.The respiratory centers in the pons and medulla control alveolar ventilation. Decreased CO 2 levels are evidenced by deep, vigorous breathing and flushed skin. If the patient has been vomiting for several days and is breathing shallowly, or if the patient has had gastric suctioning and is breathing shallowly, this may indicate elevated CO 2 levels.

Observe the patient for signs and symptoms of excessive or insufficient CO 2 levels, and report these findings to the HCP. Policies vary among facilities and may include requesting immediate recollection and retesting by the laboratory or retesting using a rapid point-of-care testing instrument at the bedside, if available.
