What is the oxygen flow rate of COPD oxygen inhalation?

Oxygen inhalation is beneficial for COPD patients. It is recommended to continue low flow oxygen inhalation, oxygen flow at 2-3 L/min. For patients with fingertip oxygen less than or equal to 88%, arterial blood gas analysis oxygen is less than 55mmHg, it is recommended to take long-term home oxygen therapy, and the oxygen inhalation time is about 10-15 hours per day. Excessive oxygen flow is easy to cause carbon dioxide retention, so special attention is needed. Oxygen can improve the state of hypoxia, can make the oxygen supply of various organs of COPD patients get effective supplement, at the same time COPD patients must quit smoking, away from occupational dust exposure, prevention of respiratory tract infection, COPD patients are very necessary.
