In the process of purchasing epidemic prevention materials, many people have the question, is it necessary to equip household oxygen production? Can old people with basic diseases take oxygen at home after they are infected with COVID-19? Let's listen to the doctor's answer. Generally, there are two diseases in the respiratory department, and the doctor may suggest that the family members buy oxygen generators for the patients - severe chronic obstructive pulmonary disease and severe interstitial pulmonary disease. The doctor reminded that in the absence of oxygen deficiency, oxygen inhalation does not really help much. If the patient is really anoxic, has obvious dyspnea and low oxygen saturation, if the situation allows, he should go to the hospital instead of taking oxygen at home to relieve himself. For patients who already have oxygen generators at home, it is not necessary to adjust the oxygen to the maximum after they are infected with COVID-19. For patients with interstitial lung disease, it is generally no problem to increase the oxygen flow, but patients with chronic obstructive pulmonary disease usually only need low flow oxygen inhalation. After they are infected with COVID-19, the oxygen flow should not be adjusted too high immediately, because after the oxygen deficiency is completely corrected, it can lead to increased carbon dioxide, resulting in patients' apathy and mental depression, also known as carbon dioxide encephalopathy, Therefore, do not arbitrarily adjust the oxygen flow of patients. In addition, we can prepare a finger clip oximeter at home according to the situation. After patients with basic diseases are infected with COVID-19, we can monitor blood oxygen saturation. If there is a significant decline compared with normal, we need to go to the hospital in time. When medical strength is relatively tight, qualified patients can temporarily take oxygen at home for observation under the guidance of doctors. (Outlook New Times)
