The gas inhaled by the patient is relatively cold and dry, and it can be considered to heat and humidify the gas inhaled by the patient with the transport emergency ventilator for a long time.
I. Main advantages of emergency transport ventilator heating and humidification:
1. Diluting sputum is more conducive to sputum suction and respiratory care, reducing the high pressure alarm of ventilator;
2. Increase the temperature of the inhaled gas, increase the comfort, and increase the blood oxygen value;
II. Commonly used heating and humidification methods of transport emergency ventilator:
1. Professional humidifier shall be equipped on the vehicle (when using on the vehicle, attention shall be paid to prevent backflow of humidified water, and the water cup shall be connected in the pipeline);
2. Now there is also a kind of consumables called artificial nose, wet heat exchanger, which can be connected to the respiratory pipeline, and also has a certain heating and humidifying effect (the artificial nose is generally used for several hours to be replaced, and the artificial nose will increase the airway resistance);
3. There are other methods for doctors with rich clinical experience, such as the use of saline drug infusion;
