What Is Oxygen therapy?
Oxygen therapy refers to the improvement of blood oxygen drop by inhaling oxygen to patients, which belongs to the category of inhalation therapy.With the improvement of medical technology, oxygen therapy has been incorporated into the normal means of medical treatment
Application Of Oxygen Therapy In Medicine
The target of oxygen therapy is mainly various patients who reduce the arterial oxygen partial pressure, including various causes of hypoxemia caused by ventilation, poor ventilation, heart failure, shock, cardiac and thoracic surgery. Patients with acute diseases should give oxygen early.There are two methods of general oxygen supply and special oxygen supply.
General oxygen supply method:
Nasal catheter or nasal congestion provides oxygen:Oxygen flow rate is 1 ~ 3L / min for adults, 0.5 ~ 1L / min for infants and young children, and the inhaled oxygen concentration can reach about 30 ~ 40%. This method is only suitable for patients with moderate blood oxygen partial pressure, nasal obstruction and mouth breathing. not good.
Open mask:The mask is placed in front of the patient's mouth and nose, and is slightly fixed without being sealed. The oxygen flow rate is 3 ~ 5L / min for adults, 2 ~ 4L / min for infants and young children, and the inhaled oxygen concentration can reach about 40 ~ 60%. This method is more comfortable and can be used for patients with severe illness and a significant decrease in oxygen partial pressure.
Oxygen in the hood:Commonly used for babies. Place the child's head in a plexiglass or plastic hood. The inhaled oxygen concentration is similar to a mask, but the required oxygen flow is greater. This method of inhaled oxygen concentration is more guaranteed, but in summer when it is hot and humid, the temperature and humidity inside the hood will be higher than the room temperature outside the hood. The child feels breathless and discomfort, which affects the rest recovery.
Special oxygen supply method:
Controlled low-flow oxygen supply:for chronic bronchitis, emphysema, and chronic pulmonary heart disease with acute lung infection and respiratory failure.For this purpose, controlled low-flow oxygen can be used, and the oxygen flow per minute should not exceed 1 ~ 2L, or a special venturi mask can be used to maintain the inhaled oxygen concentration at 24 ~ 28%
Continuous positive airway pressure oxygen supply (CPAP for short). This method has obvious effect on hypoxemia caused by increased pulmonary shunt. It is suitable for patients with severe hypoxemia such as neonatal pulmonary hyaline membrane disease and adult respiratory distress syndrome (ARDS).
So it can be seen how important oxygen therapy is to improve the oxygen supply capacity of the lungs, it can protect our health. This blog is written in the hope that you can get a way to help your health-oxygen therapy. Finally, I hope you and your family are in good health
