Oxygen inhalation method of household oxygen generator
(1) Nasal congestion and nasal catheter oxygen inhalation method: This oxygen inhalation method is simple in equipment and easy to use. There are two kinds of nasal congestion methods: single plug and double plug: the single plug method selects a suitable model and plugs it into the vestibule of one side of the nose, and is in close contact with the nasal cavity (the other nostril is open). When inhaling, only oxygen enters, so the concentration of oxygen inhalation more stable. The double plug method is to place two smaller nasal plugs in both nostrils at the same time. There is still a space around the nasal plugs, and the air can be breathed at the same time. The patient is more comfortable, but the oxygen concentration is not stable enough. 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 concentration of oxygen inhalation is constant, but it will cause discomfort and be easily blocked by secretions after a long time. 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 unbearable due to the high flow rate and impact force, and it will easily lead to dryness of the airway mucosa.
(2) Mask oxygen inhalation 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 mouth and nose, which is suitable for children without any discomfort. The airtight mask method is to put the mask tightly on the mouth and nose and fix it with an elastic band. It is suitable for people with severe hypoxia. The oxygen concentration can reach 40% to 50%. It feels more comfortable without mucous membrane irritation and dry blowing. However, the oxygen consumption is large, and there are disadvantages of inconvenient eating and expectoration.
(3) Transtracheal catheter oxygen therapy: It is a method of supplying oxygen by inserting a thinner catheter into the trachea through the nasal cavity, also known as endotracheal oxygen therapy. It is mainly suitable for patients with chronic respiratory failure caused by chronic obstructive pulmonary disease and pulmonary interstitial fibrosis who need long-term oxygen inhalation and the effect of general oxygen therapy is not good. A low-flow oxygen supply can achieve a high effect, and the oxygen consumption is very small.
(4) Electronic Pulse Oxygen Therapy: It is a new method, which can automatically send oxygen during the inhalation period through the electronic pulse device, and automatically stop oxygen delivery during the exhalation period. This is more in line with the physiological state of breathing, and greatly saves oxygen. Suitable for nasal congestion, nasal cannula and endotracheal oxygen therapy.
(5) Oxygen supply method of mechanical ventilation: when using various artificial respirators for mechanical ventilation, use the oxygen supply device on the respirator for oxygen therapy. The oxygen supply concentration (21%-100%) can be adjusted according to the needs of the condition. Oxygen cylinders are generally used as the oxygen source for oxygen therapy, and a pressure gauge is installed to indicate the amount of oxygen stored in the cylinder. When oxygen is supplied, a flow meter is installed to adjust the oxygen flow as needed.
