The concentration of oxygen in nature is much lower than that of nitrogen, about 28%, and the concentration of inhaled oxygen is about 99%. People with chronic hypoxia for a long time, such as bronchial asthma, chronic obstructive pulmonary disease, bronchiectasis, respiratory failure and even patients with advanced cancer, need long-term home oxygen therapy, and oxygen inhalation is very good for them. Especially for patients who have been hospitalized repeatedly, it is recommended to buy a home oxygen generator, which can be used for home oxygen therapy for a long time.
People with long-term work pressure can often rest and read in the oxygen bar to restore oxygen supply to their brains as soon as possible, which is conducive to improving work efficiency. Pregnant women should take enough oxygen, if the oxygen concentration is too high, it will lead to blindness of newborns. Healthy adults don't need oxygen inhalation, because normal lung function and running can meet the human body's demand for oxygen, so oxygen inhalation is unnecessary.
Matters needing attention in the use of oxygen inhalation machine
1, reasonable selection of oxygen inhalation time: attention should be paid to seriously and appropriately increasing oxygen inhalation time. Some patients usually have no or only mild hypoxemia. When they are active, nervous or tired, giving oxygen for a short time can relieve the discomfort of shortness of breath.
2, pay attention to control the oxygen flow. Patients with chronic obstructive pulmonary disease are generally 1 ~ 2 liters/min, and the flow rate should be adjusted before use. Because high-flow oxygen inhalation will aggravate the accumulation of carbon dioxide in patients with chronic obstructive pulmonary disease and cause pulmonary encephalopathy.
It is very important to pay attention to oxygen safety. The oxygen supply device shall be shockproof, oil-proof, fire-proof and heat-proof. When handling oxygen cylinders, avoid dumping and bumping to prevent explosion. Because oxygen is helpful for combustion, the oxygen cylinder should be placed in a cool place, away from fireworks and flammable materials, at least 5 meters away from the furnace and 1 meter away from the heating.
