摘要

小兒科與心臟科加護病房廣泛使用的一氧化氮(NO)吸入治療，可能對室內環境空氣造成潛在性污染，研究發現NO治療濃度在40ppm時，並未使加護病房照護病人的工作人員過度暴露於NO或二氧化氮(NO2)的環境。加護病房中NO濃度受交通狀況，氣壓，風力的影響遠高於NO吸入治療時的影響。影響個人暴露的可能因素包括：改變治療計畫，供應的氧氣與NO濃度，供應的方法與治療時加護病房室內空氣品質。NO治療時提供室內適當換氣量與避免廢氣釋放於室內，可以控制環境的暴露量。

Inhaled nitric oxide is currently administered in pediatrical and surgical intensive care units and could be an additional source of contamination of the indoor environment. Study found that inhaled nitric oxide therapy at doses up to 40ppm does not appear to pose a risk of excessive occupational exposure to nitric oxide (NO) or nitrogen dioxide (NO2) to healthcare workers during the routine delivery of critical care nursing in typical ICU setting.
The NO levels of ICU environment were more dependent on traffic, air pressure and wind than on the treatment set-up. Personal exposure levels could be affected by changes in the NO treatment protocol, the concentrations of nitric oxide as well as oxygen, delivery method and the characteristics of treatment room. Providing adequate ventilation in the NO treatment room and avoid release the waste gas can control environment exposures.
