【摘要】：目的明確Wright霧化器在霧化過程中的釋霧量變化,為建立支氣管激發(fā)試驗質(zhì)量控制標準提供依據(jù)。方法對4個不同的Wright霧化器分別加入2mL生理鹽水,在壓縮空氣(壓力=344.7kpa)的驅(qū)動下,以8、9、10L/min的流速分別霧化2分鐘各5次,分別測定其釋霧量并進行組間比較,并計算其變異率。結(jié)果 4個不同Wright霧化器以8L/min的流量霧化2分鐘的平均釋霧量分別為:0.1mL/min、0.096mL/min、0.095mL/min、0.108mL/minm(p0.05),變異率分別為:0%、10%、0%、4.54%;以9L/min的釋霧量分別為:0.125mL/min、0.124mL/min、0.098mL/min、0.130mL/min(p0.05),變異率分別為:7.69%、7.69%、5%、7.4%;以10L/min的釋霧量分別為:0.142mL/min、0.141mL/min、0.122mL/min、0.137mL/min(p0.05),變異率分別為:10%、6.89%、7.69%、7.14%。結(jié)論不同Wright霧化器在同一壓縮空氣流速下的釋霧量的差異有顯著性,同一Wright霧化器在不同壓縮空氣流速下的釋霧量有一定的變化,但變異率不超過10%。因此采用Wright霧化器進行2分鐘潮氣呼吸法支氣管激發(fā)試驗前,應對不同的霧化器分別進行釋霧量定標,以保證達到要求的釋霧量,相同的霧化器在同一流速下產(chǎn)生的釋霧量相對穩(wěn)定。
[Abstract]:Objective to determine the change of the amount of fog released from Wright atomizer during atomization, and to provide the basis for establishing the quality control standard of bronchial provocation test. Methods four different Wright nebulizers were added with 2 mL normal saline respectively. Driven by compressed air (pressure of 344.7 KPA), the atomization rate of 810L / min was measured for 2 minutes and 5 times respectively, and the fogging amount was measured and compared among the groups. Results the average fog release rate of 4 different Wright nebulizer was 0.096 mL / min 0.096 mL / min 0.096 mL / min 0.095 mL / min / min 0.095 mL / min / min / min 0.095 mL / min / min / min = 0.108 mL / min / min / min / min = 0.108 mL / min / min / min / min / min = 0.125 mL / min / min = 0.125 mL / min / min / min 0.098 mL / min / min / min = 0.096 mL / min / min / min = 0.096 mL / min / min / min = 0.096 mL / min / min = 0.095 mL / min / min, respectively. The variation rates were 0.697.695mL / min / min / min = 0.125mL / min / min / min = 0.124mL / min / min / min = 0.124mL / min / min / min 0.098mL / min / min / min, respectively, respectively, with a variation rate of 7.697.695mL / min, respectively. Don't be: 0.142mL / min 0.141mL / min 0.122mL / min = 0.137mL / min / min / min = 0.137mL / min / min / min = 0.137mL / min / min / min = 0.137mL / min / min / min = 0.137mL / min / min / min = 0.142mL / min = 0.142mL / min = 0.137mL / min / min / min = 0.137mL / min / min / min = 0.137mL / min. The amount of fog released from the same Wright atomizer at different compressed air velocities varied to a certain extent, but the variation rate was not more than 10. Therefore, before using the Wright nebulizer for 2 minutes, the bronchochallenge test of tidal breathing method was carried out. Different atomizer should be calibrated to ensure the required amount of fog release, and the same atomizer at the same flow rate is relatively stable.
