What is the oxygen concentration 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. Let's take a look at the following.

What is the oxygen concentration of type 2 respiratory failure?

First, dyspnea and cyanosis are the symptoms of patients with respiratory failure. Cyanosis is the color of lips, nails and tongue, as shown in the picture. 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.

Second: high concentration of oxygen inhalation will lead to the decrease of respiratory center's role in stimulating respiration, thus aggravating hypoxia. Such a vicious cycle will lead to the death of patients due to respiratory depression, so 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.

Third: carbon dioxide anesthesia can lead to pulmonary encephalopathy. Carbon dioxide retention can lead to indifference of expression on the basis of the original disease, poor positioning, low reaction, and the performance of daytime sleeps and wakes. *, when severe, delirium and convulsion can also occur, which can cause brain edema and hernia and death.

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.
