Symptoms of type 2 respiratory failure

summary

The blood gas analysis of type 1 * * is characterized by hypoxia and no carbon dioxide retention. According to the literal meaning, type two respiratory failure is definitely more serious than type I respiratory failure. Its blood gas analysis results indicate that both the hypoxia and carbon dioxide retention can be caused by COPD and severe asthma. * respiratory failure can lead to acid-base imbalance in the blood due to hypoxia. Type two respiratory failure patients can cause hypercapnia due to hypoxia and carbon dioxide retention, and also cause pulmonary encephalopathy due to carbon dioxide anesthesia.

Symptoms of type 2 respiratory failure

Dyspnea and cyanosis are symptoms that patients with respiratory failure have to mention. Cyanosis is characterized by dark purple color of lips, nails and tongue, as shown in the figure. When the carbon dioxide is moderately elevated, the superficial veins and capillaries of the extremities are dilated, showing that the limbs are flushed, sweating, warm, and when carbon dioxide retention is serious, there will be * congestion of the bulbar conjunctiva.

Carbon dioxide anesthesia can cause pulmonary encephalopathy. Carbon dioxide retention can lead to indifference of expression on the basis of the original disease, poor location, low reaction rate, the performance of daytime sleeps and waking up, severe delirium *, convulsions, etc., which can cause brain edema and hernia and death.

High concentration of oxygen inhalation will lead to the decrease of respiratory center's function of exciting respiration, thus aggravating hypoxia. Such a vicious cycle will lead to the death of patients due to respiratory depression. Therefore, low concentration and low flow oxygen inhalation should be used. Keeping the airway unobstructed is the most important measure. We should clean up the secretion of the airway in time, and tracheotomy when necessary.

matters needing attention

Avoid the inducement of respiratory failure, pay attention to strengthen the physique in daily life, and actively treat the primary disease of respiratory failure. We should make reasonable rest and activity plans, pay attention to the combination of work and rest, and strengthen self-care measures.
