Failure to Clean and Maintain Oxygen Concentrators Used for Resident Oxygen Therapy
Summary
Nursing and maintenance staff failed to ensure that oxygen concentrators used by multiple residents were kept clean and properly maintained, resulting in visibly dirty equipment with dust and debris on vents and internal filters. For one resident with dementia and breast cancer receiving continuous O2 at 2 L/min via nasal cannula for shortness of breath, surveyors observed dust on the outside vent and large areas of dust buildup inside the concentrator’s filter compartment. The Maintenance Supervisor confirmed the internal filter needed to be changed and the concentrator needed overall cleaning, and the Infection Preventionist agreed the concentrator needed cleaning and filter change and stated it could be harmful to use the compressor when the filter was so dirty. Another resident with COPD, hypoxemia, and a history of recurrent pneumonia had an order for continuous O2 at 2 L/min via nasal cannula. During observation, dust buildup was seen on the outside vent and covering the outside of the concentrator. Later, when the filter compartment was opened, scattered areas of dust buildup were found inside, and both the Maintenance Supervisor and Infection Preventionist confirmed the internal filter needed to be changed and the concentrator cleaned. A third resident dependent on supplemental oxygen with an order for continuous O2 at 2 L/min via nasal cannula was observed using a concentrator with dust buildup on the outside vents; when opened, the internal compartment had a layer of white dust and debris throughout and a discolored internal filter. The Maintenance Supervisor confirmed the filter needed to be changed, the Infection Preventionist stated a dirty concentrator was not good for a resident receiving oxygen therapy, and the resident reported that no one had been cleaning the concentrator. A fourth resident with COPD and chronic respiratory failure with hypoxia, ordered to receive continuous O2 at 3 L/min via nasal cannula, was observed receiving O2 at 2 L/min from a concentrator that felt hot to the touch and had a large amount of dust buildup on the outside vent and dust covering the entire machine. When the concentrator’s filter compartment was opened, one side filter hidden by a screwed-in plate and the internal compartment both had a thick layer of dust buildup. The Maintenance Supervisor stated this concentrator belonged to the facility and that it was his responsibility to ensure facility-owned equipment was operating effectively and in clean condition. He later stated his department had no cleaning logs for facility-owned concentrators, oxygen concentrators were not listed on the housekeeping daily cleaning guide, and he could not find vendor maintenance and cleaning logs. The Administrator reported two facility-owned concentrators had been delivered the prior year, there was no record of which machine was placed for this resident or when, and the Maintenance Supervisor later stated the concentrator for this resident had been in place since delivery. The facility’s policy and the owner’s manual required routine exterior cleaning and regular filter maintenance, including more frequent cleaning and filter changes when operated continuously, which were not documented or demonstrated in practice. The Infection Preventionist stated the dusty concentrators posed an infection risk because dust and debris can hold bacteria, spores, and other pathogens that can enter the resident’s respiratory system, placing residents at risk for chronic cough, delayed healing, or other respiratory diseases.
