Medical oxygen (Medical oxygen ) is the abbreviation of medical oxygen , also known as medical oxygen. refers to the separation of oxygen in the atmosphere by using a deep-cold separation method to supply oxygen used to treat patients.
Preparation
Use deep-cold separation method to separate the oxygen in the atmosphere. After multiple compression and cooling, the gaseous oxygen is then processed under minus-183°C at low temperature. The gaseous oxygen is converted into liquid oxygen. Repeatedly distillation to purify and remove dust and impurities, carbon monoxide , carbon dioxide , and water vapor are compressed and gasified and directly filled with oxygen cylinder .
oxygen purity
2
bottle medical oxygen purity national standard is ≥99.5%, and the national standard for oxygen produced by oxygen generator does not stipulate medical oxygen standards. Regardless of whether the oxygen generator uses molecular sieve to generate oxygen or oxygen-enriching films, the oxygen purity is lower than that of bottled medical oxygen. When using an oxygen generator to inhale oxygen, be sure to open the windows for ventilation or lead the oxygen generator air duct to the outdoors to extract air to increase the oxygen generator concentration.
Common forms
is commonly used in bottled medical oxygen, in a gas state, and low-temperature liquid oxygen must be stored in a low-temperature liquid oxygen tank, which is commonly used as large oxygen storage equipment.
Understand and record the vital signs of oxygen inhalers
4 vital signs: respiratory rate, body temperature, heart rate , blood pressure, especially respiratory rate, heart rate and blood pressure can be used as indicators of whether or not oxygen is inhaled. When the sign value changes significantly compared with daily records, it is recorded and started inhaling oxygen.
Open the oxygen bottle switch
As shown in the picture on the right, the main switch of the oxygen bottle is located directly above the oxygen bottle, with a handwheel that can be rotated by hand. It is advisable to rotate the handwheel in the counterclockwise direction for half a turn to one turn (the opening angle will cause the pressure to be unable to be released). The switch direction of the cylinder is the same as that of the faucet, and you can remember it by switching the faucet. If you hear a leaky sound after opening, you should check the leak point and close the oxygen cylinder valve; if the sound is very loud, you should immediately close the oxygen cylinder valve clockwise and contact the medical oxygen supplier.
Observe the oxygen pressure gauge
After opening the oxygen cylinder, the pressure gauge pointer will jump up, and the moving range of the pointer is between 0 and 15Mp, indicating the amount of oxygen stored in the oxygen cylinder. The pressure gauge can also calculate the speed of oxygen usage. After opening the oxygen cylinder, the pressure gauge pointer will jump up. The moving range of the pointer is between 0 and 15Mp, indicating the amount of oxygen stored in the oxygen cylinder. The pressure gauge can also calculate the speed of oxygen usage.
Adjust flow regulation valve Observation flowmeter
Adjust the flow size according to the current usage requirements, the conventional sub-health flow is 0.5~1.5, treatment flow is 1.5~3, first aid: above 3. Note that the main indicator affecting oxygen inhalation flow is lung capacity . Please adjust the flow appropriately according to the lung capacity of the oxygen inhaler. Oxygen inhaler weighing less than 30kg needs to adjust the oxygen inhalation flow based on age. Please consult a doctor for details.

is from the oxygen inhalers wearing oxygen inhalers. Oxygen inhalers other than first aid usually uses nasal plug-in oxygen inhalers. Use an oxygen inhalation mask during first aid. Infants and young children cannot use an oxygen inhalation tube and an oxygen inhalation mask because their lung capacity is too large. They should use a diffuse oxygen inhalation method to inhale oxygen (after allowing oxygen and air to be fully mixed, they should be inhaled while monitoring the oxygen concentration).
Detection of vital signs to determine the effect of oxygen inhalation
If vital signs change due to hypoxia, shortness of breath after oxygen inhalation will be relieved, the heart rate will gradually move closer to the basal heart rate. When the blood pressure is abnormally raised, the blood pressure will gradually stabilize, and the blood oxygen value will gradually increase (the blood oxygen value is less than 95%). If possible, the vital signs can be recorded so that it can be used as a reference material during medical treatment or to explore the changes in the physical condition of the oxygen inhaler by yourself, so as to prevent diseases
Operation when medical oxygen cylinders stop oxygen inhalation
Close the oxygen cylinder switch → Turn the oxygen cylinder valve clockwise to close the medical oxygen cylinder.After closing, it can be observed that the pressure gauge gradually returns to the position of 0. When the pointer returns to the position of 0, the bubbles in the tidal bottle will gradually decrease until it stops bubble. This means that the oxygen bottle valve has been completely closed. The overall oxygen absorption process is over.
