Have you ever experienced the feeling of suffocation?
I don't, but as a doctor, I can deeply feel the "pain of breathing" for patients with respiratory dysfunction, especially lung disease and heart disease—the pain of gasping in silence and gradually sliding to death, which is an indescribable fear in the world.
Whether outpatient or inpatient for patients with pulmonary dysfunction or decline, there is a reference to oxygen therapy (oxygen therapy) in basic treatment.
Many patients or their families have a misunderstanding that in the TV series, only rescue will be needed, or that patients who need oxygen are very critically ill, in fact, this view is aimed at some acute diseases, which is correct.
However, it is not correct for patients with acute symptoms - remission or for patients with chronic diseases who regularly visit hospital outpatients, because most patients with chronic diseases have different degrees of decreased lung function and low oxygen saturation, and such patients often have a special prescription in addition to drugs - home oxygen therapy.
Next, we will introduce home oxygen therapy to you through a few questions.
Question 1:
Is "home oxygen therapy" all day long?
A: Home oxygen therapy is an extension of out-of-hospital treatment and the maintenance of the patient's condition. Oxygen inhalation time varies for patients with different degrees of disease. So home oxygen therapy doesn't mean that you need to take oxygen all the time.
A: For example, patients with chronic diseases such as pulmonary dysfunction, pulmonary edema, copernic obstruction, and asthma often suffer from hypoxia (hypoxemia) due to disease, season, and temperature, which not only aggravates the condition, but also endangers life when it is severe. Long-term home oxygen therapy patients can ensure oxygen therapy, not only to improve hypoxia, but also to reduce related complications, prevent exacerbation or acute onset, improve patient comfort and improve survival.
A: (1) Patients with chronic hypoxemia
Such as: chronic obstructive pulmonary disease, pulmonary interstitial fibrosis, pulmonary hypertension, pulmonary heart disease, severe heart failure, etc.;
(2) Patients with hypoxia
Patients with hypoxia caused by pulmonary diseases, large daily physical exertion, excessive mental tension, and nighttime sleep on their backs can be treated with regular intermittent short-term oxygen inhalation or intermittent emergency oxygen inhalation.
Such as: adult congenital heart disease, coronary heart disease, patients with a history of cerebral infarction, excessive obesity, lung cancer, etc.
(3) Patients in the convalescent period of acute diseases
Such as: acute myocardial infarction, cerebral infarction, myocarditis severe, severe pneumonia, or after cardiothoracic surgery.
Intermittent oxygen therapy is used to improve hypoxia, improve heart, lung, and brain function, and promote recovery.
A: Not recommended.
Oxygen therapy is a common clinical treatment, and home oxygen therapy is just an extension of oxygen therapy outside the hospital.
Whether the patient needs home oxygen therapy, as well as the specific use and frequency of oxygen therapy, should be recommended by a medical professional after evaluation.
In general, healthy people or those without related diseases, breathing air in an environment within the normal atmospheric pressure range is enough to maintain normal physiological needs, and long-term excessive oxygen inhalation will bring adverse reactions.
