The development of home oxygen concentrators has greatly facilitated our lives and promoted the vigorous development of elderly care. Let’s let the sales editor of billions of billions of oxygen inhalers introduce you to how to use home oxygen concentrators for health care ?
Oxygen therapy method
1. Oxygen should be inhaled especially at night.
2. Choose the time of oxygen therapy scientifically; for some patients with mild hypoxia, oxygen therapy for half an hour to 1 hour a day is enough; for patients with severe bronchitis, cardiovascular and cerebrovascular diseases and severe asthma Said that family oxygen therapy experts recommend more than 12 hours of oxygen therapy a day to ensure that enough oxygen is needed every day.
3. Choose an appropriate oxygen flow; for patients with general hypoxia, you can choose an oxygen flow of 2L~3L/min for oxygen therapy; for patients with severe hypoxia, an oxygen flow of 5L/min or more is more suitable . It is best to consult the relevant treating physician and choose the oxygen flow according to the actual situation of the patient.
4. The water in the humidification tank should be replaced frequently; generally speaking, when the water in the humidification tank is slightly turbid, the humidification tank must be replaced and cleaned at this time. Home oxygen therapy experts recommend that the water in the humidification tank be replaced once a day and cleaned, so as to ensure oxygen hygiene.
5. The nasal plug and snorting oxygen suction tube should be cleaned and disinfected regularly; it is best to disinfect every day, and new nasal plug and snorting oxygen suction tube should be replaced every week. The combination of the third and fourth points can maximize oxygen hygiene.
6. Pay attention to the safety measures during oxygen therapy; because oxygen has the ability to support combustion, it should be kept away from open flames when inhaling oxygen, and should be placed in a cool and ventilated place when not using a household oxygen generator.
Precautions for oxygen therapy
(1) Closely observe the effect of oxygen therapy. If symptoms such as dyspnea are alleviated or relieved, and the heartbeat is normal or close to normal, it indicates that oxygen therapy is effective. Otherwise, the cause should be found and dealt with in time.
(2) High-concentration oxygen supply should not take too long. It is generally believed that if the oxygen concentration is more than 60%, if it lasts for more than 24 hours, oxygen poisoning may occur.
(3) High-concentration oxygen inhalation for patients with acute exacerbations of chronic obstructive pulmonary disease may lead to respiratory depression and worsen the condition. Generally, controlled (ie, low-concentration continuous) oxygen inhalation is appropriate.
(4) Oxygen therapy should pay attention to heating and humidification. Maintaining a temperature of 37°C and 95%-100% humidity in the respiratory tract are necessary conditions for the normal clearance of the mucociliary system. Therefore, inhaled oxygen should pass through a humidification bottle and necessary heating devices. , In order to prevent inhalation of dry and cold oxygen to stimulate the airway mucosa, cause phlegm to dry up and affect the “scavenger” function of cilia.
(5) To prevent pollution and duct blockage, nasal congestion, oxygen ducts, humidification and heating devices, and ventilator pipeline systems should be regularly replaced and cleaned and disinfected to prevent cross-infection. Oxygen catheters and nasal congestion should always be checked for obstruction of secretions and replaced in time. To ensure effective and safe oxygen therapy.
Oxygen is very important to the human body. Under normal conditions, healthy people breathe air naturally and use the oxygen in it to maintain metabolic needs. In case of illness or certain abnormal conditions, it is necessary to inhale oxygen through certain equipment at home, clinic, or hospital.
Oxygen inhalation method
(1) Nasal congestion and nasal catheter oxygen inhalation method: This oxygen inhalation method is simple in equipment and convenient to use. There are two types of nasal congestion: single-plug and double-plug: The single-plug method uses a suitable model to plug in the vestibule of the nose, and it is in close contact with the nasal cavity (the other nostril is open), and only oxygen is injected when inhaling, so the oxygen concentration More stable. The double plug method is to place two smaller nasal congestion at the same time on both sides of the nostril. There is still a gap around the nasal congestion, and the patient can breathe air at the same time. The patient is more comfortable but the oxygen concentration is not stable enough. The nasal catheter method is to insert a catheter (commonly used urinary catheter) through the nostril into the back of the soft palate at the top of the nasal cavity. The oxygen concentration is constant, but after a long period of time, it will feel uncomfortable and easily blocked by secretions. Nasal congestion and nasal catheter oxygen inhalation are generally only suitable for low-flow oxygen supply. If the flow rate is relatively large, it will be intolerable due to the large flow rate and impact force, and it is easy to cause the airway mucosa to dry.
(2) Mask oxygen method: can be divided into open and closed mask method. The open type is to place the mask 1 to 3 cm away from the patient’s nose, which is suitable for children without any discomfort. The airtight mask method is to tightly cover the mouth and nose and fix it with elastic bands. It is suitable for people with severe hypoxia. The oxygen concentration can reach 40%-50%, and it feels more comfortable without mucosal irritation and dry blowing. However, the oxygen consumption is large, and there is the disadvantage of inconvenience in eating and expectorating.
(3) Transtracheal oxygen therapy: It is a method of oxygen supply in which a thinner catheter is inserted into the trachea through the nasal cavity, also called intratracheal oxygen therapy. It is mainly suitable for chronic obstructive pulmonary disease and pulmonary fibrosis caused by chronic respiratory failure requiring long-term oxygen inhalation, but the general oxygen therapy effect is not good. Because the catheter is used to directly supply oxygen into the trachea, the curative effect can be significantly improved. Low-flow oxygen supply can achieve higher results, and the oxygen consumption is small.
(4) Electronic Pulse Oxygen Therapy: It is a new method that can automatically deliver oxygen during the inhalation period through an electronic pulse device, and automatically stop the oxygen delivery during the expiration period. This is more in line with the physiological state of breathing, and greatly saves oxygen. Suitable for nasal congestion, nasal catheter and intratracheal oxygen therapy.
(5) Mechanical ventilation and oxygen supply method: that is, when various artificial respirators are used for mechanical ventilation, the oxygen supply device on the ventilator is used for oxygen therapy. The oxygen supply concentration can be adjusted according to the condition of the disease (21% to 100%). The oxygen source of oxygen therapy generally uses oxygen cylinders, and a pressure gauge is installed to indicate the amount of oxygen in the bottle. A flow meter is installed when oxygen is supplied, and the oxygen flow is adjusted as needed.
