The purpose of oxygen intake in coronary heart disease is to improve myocardial hypoxia; common methods of oxygen intake include nasal catheter oxygen intake, mask oxygen intake method; the precautions for oxygen intake include oxygen flow rate and time of oxygen intake.
1. The purpose of oxygen intake is: to improve the patient’s oxygen saturation and arterial oxygen saturation, chest tightness, palpitations and other symptoms.
2. Methods of oxygen intake
(1) Nasal catheter oxygenation method, which is divided into unilateral nasal catheter oxygenation and bilateral nasal catheter oxygenation.
(2) Oxygen inhalation by mask, which is often used for patients with high oxygen flow.
3. Precautions for oxygen intake
(1) Oxygen flow: the oxygen flow should be selected according to the patient’s condition, too high can easily cause carbon dioxide retention; too low can not achieve the effect of oxygen therapy.
(2) Oxygen can not be around the presence of open flames, the risk of explosion.
Specific condition specific analysis, need to be carried out under the guidance of a professional doctor.
