Inhaled oxygen concentration

  Inhaled oxygen concentration refers to the concentration of oxygen inhaled and is commonly used to treat respiratory diseases and improve quality of life. Different people have different requirements for oxygen, so the concentration of oxygen inhaled will vary.

  In general, the inhaled oxygen concentration should be between 21% and 36%. Too high or too low an inhaled oxygen concentration can have adverse effects on the body. High inhaled oxygen concentrations can increase airway resistance, resulting in breathing difficulties; Too low inhaled oxygen concentration will affect the function of the respiratory center, making patients feel tired, dizzy, nausea and other uncomfortable symptoms.
  When performing oxygen therapy at home, it is generally recommended to use oxygen with an oxygen concentration of 24 to 28 percent. If oxygen is administered through a mask or nasal catheter, oxygen with an oxygen concentration of 21 to 25 percent is recommended.

  In addition to oxygen concentration, the way oxygen is inhaled also affects the effect of the concentration. For example, when inhaling oxygen from an oxygen mask or cylinder, it is recommended to use a higher concentration (about 25%) of oxygen to ensure that oxygen can fully penetrate the lungs and supply the needed oxygen. When inhaling oxygen through a nasal catheter or mask, a lower concentration of oxygen (about 21%) is recommended to reduce mucosal damage and fatigue.

  In short, inhaled oxygen concentration is a very important issue, different groups of people have different needs and ways of inhaling oxygen, so it is necessary to choose the appropriate inhalation oxygen concentration according to personal circumstances. In the process of use, attention should be paid to the correct use of oxygen inhalation equipment and reasonable selection of concentration to avoid adverse reactions and complications.
