After an acute heart attack, oxygen is usually needed if there are uncomfortable symptoms such as chest tightness, suffocation, shortness of breath, or when oxygen saturation is lower than normal.
Acute infarction is a common acute cardiovascular system disease, its main manifestation is severe and long-lasting chest pain, and even serious arrhythmia, shock, oxygen saturation decreased, etc. When there is suffocation, breathlessness and other discomfort or oxygen saturation decreased, it is necessary to give oxygen inhalation in a timely manner, to avoid the occurrence of hypoxemia and acid-base electrolyte disorders. Oxygen inhalation increases the oxygen supply to the myocardium, and at the same time increases the blood supply to the myocardium relatively.
Acute myocardial infarction is mainly due to occlusion of the major blood vessels supplying blood flow to the heart and interruption of blood flow, which leads to ischemic necrosis of the myocardium. Daily rest, regular medication, emotional control, and a good state of mind should be observed, and prompt medical attention should be sought if there is any serious discomfort.
