Multipatient use and prolonged use of prefilled disposable oxygen humidifier bottles (Aquapak 301, Respiratory Care, Inc., Arlington Heights, IL) were evaluated by performing microbiologic monitoring and a cost analysis on bottles used for varying numbers of patients and lengths of time.
Humidifiers were hung for a maximum of one month. Monitoring was conducted in 6 different nursing areas. Quantitative cultures were done for aerobes and Legionella. Reusable humidifier bottles also were monitored.
Cultures were obtained from 1,311 disposable and 60 reusable humidifiers. No significant bacterial contamination was detected in the prefilled disposable oxygen humidifier units. Ten percent of the reusable bottles were contaminated by organisms associated with skin flora.
Multipatient use and increased duration of use of disposable humidifiers result in cost savings without increasing patient risk. Restricted multipatient use of prefilled disposable oxygen humidifier bottles for a period of one month is a safe and cost-efficient practice.
通过对用于不同患者数量和使用时长的预充式一次性氧气湿化瓶（Aquapak 301，Respiratory Care公司，伊利诺伊州阿灵顿高地）进行微生物监测和成本分析，评估其多患者使用情况和长期使用情况。
湿化瓶悬挂使用最长1个月。在6个不同护理区域进行监测。对需氧菌和军团菌进行定量培养。同时也对可重复使用的湿化瓶进行监测。
从1311个一次性湿化瓶和60个可重复使用的湿化瓶中采集培养样本。预充式一次性氧气湿化瓶未检测到明显的细菌污染。10%的可重复使用湿化瓶被与皮肤菌群相关的微生物污染。
多患者使用一次性湿化瓶并延长使用时长可节省成本，且不会增加患者风险。预充式一次性氧气湿化瓶限制多患者使用1个月是一种安全且具有成本效益的做法。
