Oxygen Humidifier Bottles Left Empty and Unlabeled
Summary
Supplemental oxygen was not maintained in accordance with professional standards of practice for two residents. Resident 19 had diagnoses including COPD with acute exacerbation and type 2 diabetes mellitus, and was ordered oxygen at 1 L/min via nasal cannula as needed for shortness of breath to keep oxygen saturation above 90%. During observation, Resident 19’s oxygen concentrator had an empty humidifier bottle, and the bottle was labeled with a date of 4/7/26. A nurse later confirmed the bottle was empty and stated humidifier bottles should be replaced when they were no longer bubbling and should not be allowed to become completely empty before replacement. Resident 19’s record did not contain a physician order for the humidifier bottle, even though the bottle was labeled RX. The medical director stated that items labeled RX should have a physician’s order before use, and that she had overlooked the absence of an order for the oxygen humidifier bottle. The infection preventionist stated nurses were expected to check oxygen humidifier bottles every 24 hours, replace them according to manufacturer guidelines, and use a humidifier for comfort and moisture when indicated. Resident 19’s care plan also included an intervention to change the oxygen humidifier in accordance with manufacturer’s guidelines. Resident 80, who had diagnoses including necrotizing fasciitis, Fournier gangrene, and COPD, was observed with an oxygen humidifier bottle that was empty and not labeled with the date it was set up. A nurse acknowledged the bottle was empty and unlabeled and stated it should have been replaced and properly labeled. The infection preventionist and DON both stated that an empty humidifier was ineffective and that the bottle needed to be labeled with the date and time so the length of use could be determined. The facility policy stated oxygen humidification must be provided, maintained, and replaced to prevent infection, ensure proper device function, and comply with manufacturer instructions and accepted standards of practice, and that a prefilled humidifier should be replaced whenever the sterile water is empty.
