1, oxygen nebulization inhalation with O2 as a gas source, oxygen flow 6~10L/min, in line with the principle of oxygen therapy for respiratory infectious diseases, oxygen nebulization inhalation has a high concentration of nebulized liquid, small particles of small interference with the vital signs, phlegm expectoration is good, not easy to irritation choking reaction, easy to operate, etc., is easy to be accepted by the patients and There are no side effects, so the oxygen-driven nebulizer is more suitable for patients with respiratory tract infectious diseases.
2, ultrasonic nebulization inhalation gas humidity is often too high, reducing the concentration of inhaled oxygen, can make the arterial partial pressure of oxygen drop, feel the chest tightness and shortness of breath aggravated.
3, especially in patients with chronic obstructive pulmonary disease, lung ventilation and ventilation dysfunction, a large number of ultrasonic nebulization not only affects the normal entry of oxygen, and at the same time is not conducive to CO2 discharge.
4, respiratory infectious diseases patients oxygen therapy is very important, ultrasonic nebulization inhalation of fog volume impulse than the flow of oxygen in the air, the oxygen content of the inhaled gas is also lower than that of the normal air, resulting in hypoxia.
