How to choose the right oxygen inhalation method

  Oxygen inhalation is oxygen therapy, which is a way to relieve hypoxia.
  It is widely used in clinical respiratory diseases, such as respiratory failure, COPD, chronic bronchitis, or cardiovascular and cerebrovascular ischemic diseases, such as cerebral infarction and coronary heart disease. Patients in childbirth or before and after surgery, and patients with massive bleeding can be treated with oxygen therapy.

There are several main ways to take oxygen:
  The first, nasal catheter oxygen, is the most common method. A nasal catheter is inserted into the tip of the nasal cavity and oxygen is administered.
  The second, mask oxygen method, the mask covers the patient's mouth and nose to give oxygen.
  The third is oral oxygen inhalation. If the patient is breathing through the mouth, a catheter can be placed into the mouth to receive oxygen. There are also some ways to take oxygen, which is to supply oxygen through a ventilator.
  When inhaling oxygen, medical oxygen must be used. When the nasal catheter absorbs oxygen, the oxygen flow rate is generally not too large. In some COPD patients, oxygen should be given at a low concentration.
