Matters needing attention in oxygen inhalation of lung cancer

summary

Grandma got lung cancer. She has a special oxygen inhaler at home. She needs to inhale oxygen frequently. Now let's talk about the precautions of oxygen inhalation for lung cancer.

Matters needing attention in oxygen inhalation of lung cancer

First: low concentration of oxygen (oxygen concentration is less than 50%): it is generally used for chronic bronchitis, emphysema, pulmonary heart disease, also known as chronic obstructive pulmonary disease. When the chronic respiratory failure is decompensated, the increase of partial pressure of blood oxygen must be considered. Too high partial pressure of blood oxygen can weaken the reflex stimulation of carotid sinus to the respiratory center, so as to reduce the ventilation volume and aggravate the oxidative stress * carbon retention. Therefore, it is necessary to use oxygen cautiously, generally use low concentration continuous oxygen inhalation, and add mechanical respiration treatment when necessary.

Second: high concentration oxygen (oxygen concentration more than 50%): in acute respiratory failure, such as respiratory, cardiac arrest, acute respiratory distress syndrome, acute poisoning (such as carbon monoxide poisoning, namely gas poisoning) respiratory depression, we must use high concentration or pure oxygen to rescue, but not long-term use, in order to prevent oxygen poisoning or other complications.

In addition, ginsenoside can prevent the recurrence rate of lung cancer by more than 16% in the fifth year, and can be combined with chemotherapy.

matters needing attention

Attention should be paid to the side effects of improper use of oxygen, especially for patients. It should be used under the guidance of doctors.
