Contraindications of mask oxygen:
1. Oxygen inhalation is beneficial to people with respiratory dysfunction and can correct hypoxia. 2. Excessive oxygen inhalation will increase the oxygen concentration of the inhaled air, which may lead to oxygen poisoning. 3. Enlarged alveoli is not conducive to oxygen inhalation. 4. Oxygen is not suitable for facial congestion. 5. Do not inhale oxygen just after strenuous exercise. Mask oxygen is a method to transfer the oxygen required for breathing from the storage tank to the human lungs. There are mainly medical oxygen masks, aviation oxygen masks and oxygen masks used by airline passengers. They play an important role in the treatment of diseases. Oxygen The method and flow of inhalation are related to the patient's condition. High-flow oxygen inhalation means that the inhaled oxygen concentration exceeds 40%. It is common in acute lung injury and severe pneumonia. It is suitable for type I respiratory failure and requires systematic monitoring during treatment. If there is a decrease in systolic blood pressure, decreased pulse pressure, etc., it means that oxygen therapy does not work, and arterial blood gas analysis is a more accurate inspection method.
How to use oxygen mask
1
Wash your hands, prepare the items you need, and check repeatedly to make sure they are in use.
2
Check the date of the oxygen inhalation tube, check for leaks, connect the oxygen inhalation tube and the humidification bottle, and the connection is secure, turn on the oxygen switch, and adjust the oxygen flow. Connect the oxygen tube and the mask to ensure that the connection is tight and will not fall off.
3
After adjusting the flow rate, cover the mouth and nose with the oxygen mask and adjust the tightness. Record oxygen time and oxygen flow in time. Observe the state of oxygen inhalation, and close it in time if there is any abnormal state.
4
When the oxygen time is reached, turn it off in time, remove the mask, turn off the flow meter, record the time when oxygen is disabled, and wash your hands.
Oxygen mask is an emergency rescue device that provides oxygen to passengers. If the cabin suddenly loses airtightness or encounters other hypoxic conditions, passengers can get oxygen masks to supplement oxygen at any time.
oxygen mask provides a way to transfer the oxygen needed for breathing from the storage tank to the human lungs. There are mainly medical oxygen masks, aviation oxygen masks and oxygen masks used by airline passengers, which play an important role in curing diseases and protecting the safety of passengers and pilots. Mainly made of plastic, silicone, or rubber.
After the plane flies to a certain altitude, pressurize the cabin. If the aircraft cabin loses pressure, it will cause hypoxia, and passengers will feel dizzy, lose consciousness, and even endanger their lives in the absence of oxygen. In the case of cabin depressurization at different altitudes, the duration of hypoxia that a person can withstand is different. The higher the flight altitude, the less time to withstand. In civil aviation airliners, each person’s seat is equipped with a personal oxygen mask for emergency use, so there is no need to fight to avoid pulling the oxygen mask and delaying use.
The oxygen mask is connected to the automatic coupler through a slender rubber oxygen supply tube and a bayonet joint. Oxygen continuously flows into the air storage bag of the mask. The gas storage bag first stores gas, and then when it expands, it can hold a certain amount of oxygen. When the passenger takes a deep breath to empty the air storage bag, the air intake valve on the mask can allow oxygen to enter.
In the event of decompression in the aircraft cabin, the oxygen mask will automatically be thrown down from the cabin roof. Above the passenger seat, there is an emergency manual release of the oxygen mask with a "push" mark. After pushing open, the oxygen mask will automatically lower in front of the passengers. On the release board, there are graphics and text instructions on how to use it. Passengers should follow the instructions correctly.
