Precautions for using oxygen concentrator

Precautions when using an oxygen concentrator

• Patients who purchase an oxygen concentrator should read the instructions carefully before using it.
• When using the oxygen concentrator, keep away from open flames to avoid fire.
• It is forbidden to start the machine without installing filters and filters.
• Remember to cut off the power supply when cleaning the oxygen concentrator, filters, etc. or replacing the fuse.
• The oxygen concentrator must be placed stably, otherwise it will increase the noise of the oxygen concentrator operation.
• The water level in the humidifidier bottle should not be too high (the water level should be half of the cup body), otherwise the water in the cup will easily overflow or enter the oxygen suction tube.
• When the oxygen concentrator is not used for a long time, please cut off the power supply, pour out the water in the humidification cup, wipe the surface of the oxygen concentrator clean, cover it with a plastic cover, and store it in a dry place without sunlight.
• When the oxygen generator is turned on, do not place the flow meter float at the zero position.
• When the oxygen concentrator is working, try to place it in a clean indoor location, with a distance of no less than 20 cm from the wall or other surrounding objects.
• When patients use the oxygen concentrator, in case there is a power outage or other malfunction that affects the patient’s use of oxygen and causes unexpected events, please prepare other emergency measures.
• Pay special attention when filling the oxygen bag with the oxygen generator. After the oxygen bag is filled, you must first unplug the oxygen bag tube and then turn off the oxygen generator switch. Otherwise, it is easy to cause the negative pressure of the water in the humidification cup to be sucked back into the system. oxygen machine, causing the oxygen generator to malfunction.
• During transportation and storage, it is strictly prohibited to place it horizontally, upside down, exposed to moisture or direct sunlight.

What you need to know when administering oxygen therapy at home

1. Reasonably choose the oxygen inhalation time.For patients with severe chronic bronchitis, emphysema, accompanied by clear lung function abnormalities, and the partial pressure of oxygen continues to be lower than 60 mm, they should be given more than 15 hours of oxygen therapy every day; for some patients, there is usually no or only mild hypotension. Oxygenemia, during activity, tension or exertion, giving oxygen for a short period of time can relieve the discomfort of “shortness of breath”.
2. Pay attention to controlling oxygen flow.For patients with COPD, the flow rate is generally 1-2 liters/minute, and the flow rate should be adjusted before use. Because high-flow oxygen inhalation can aggravate carbon dioxide accumulation in COPD patients and cause pulmonary encephalopathy.
3. It is most important to pay attention to oxygen safety. The oxygen supply device should be shock-proof, oil-proof, fire-proof and heat-proof. When transporting oxygen bottles, avoid tipping and impact to prevent explosion;Because oxygen can support combustion, oxygen bottles should be placed in a cool place, away from fireworks and flammable materials, at least 5 meters away from the stove and 1 meter away from the heater.
4. Pay attention to oxygen humidification.The humidity of the oxygen released from the compression bottle is mostly less than 4%. For low-flow oxygen supply, a bubble-type humidification bottle is generally used. 1/2 of pure water or distilled water should be added to the humidification bottle.
5. The oxygen in the oxygen bottle cannot be used up. Generally, 1 mPa needs to be left to prevent dust and impurities from entering the bottle and causing an explosion during re-inflation.
6. Nasal cannulas, nasal plugs, humidification bottles, etc. should be disinfected regularly.

Oxygen inhalation directly increases the oxygen content of arterial blood

The human body uses approximately 70-80 square meters of alveoli and hemoglobin in the 6 billion capillaries covering the alveoli to achieve gas exchange of oxygen and carbon dioxide.Hemoglobin contains divalent iron, which combines with oxygen in the lungs where the oxygen partial pressure is high, turning it into bright red and becoming oxygenated hemoglobin. It transports oxygen to various tissues through arteries and capillaries, and releases oxygen into cell tissues, turning it into dark red. of reduced hemoglobin,It combines carbon dioxide within tissue cells, exchanges it through biochemical forms, and ultimately removes carbon dioxide from the body. Therefore, only by inhaling more oxygen and increasing the oxygen pressure in the alveoli can the opportunity for hemoglobin to combine with oxygen be increased.

Oxygen inhalation only improves rather than changes the body’s natural physiological state and biochemical environment.

The oxygen we inhale is familiar to us every day, so anyone can adapt to it immediately without any discomfort.

Low-flow oxygen therapy and oxygen health care do not require special guidance, are effective and fast, and are beneficial and harmless. If you have a home oxygen concentrator at home, you can receive treatment or health care at any time without going to a hospital or special place for treatment.

If there is an emergency to grab the ball, oxygen therapy is an indispensable and important means to avoid irreversible losses caused by acute hypoxia.

There is no dependence, because the oxygen we have breathed in throughout our lives is not a strange drug. The human body has already adapted to this substance. Inhaling oxygen only improves the hypoxic state and relieves the pain of hypoxic state. It will not change the state of the nervous system itself. Stop There will be no discomfort after inhaling oxygen, so there is no dependence.
