Improper CPAP Humidifier Water Use and Interruption of Ordered CPAP Therapy
Summary
The deficiency involves the facility’s failure to provide respiratory care consistent with professional standards and the resident’s care plan for a resident requiring CPAP therapy for obstructive sleep apnea. The resident was an elderly female with severe cognitive impairment, dementia, and a cognitive communication deficit, who had a physician’s order for nightly CPAP use at a prescribed setting. A prior sleep study documented severe obstructive sleep apnea with numerous obstructive apneas and hypopneas, significant respiratory arousals, and oxygen desaturations, leading to the order for nightly CPAP use. The resident’s comprehensive care plan required that the CPAP humidifier reservoir be filled with distilled water only each night and that the CPAP equipment be cleaned according to specified procedures. On the evening in question, RN A entered the resident’s room, woke the resident, and had her apply the CPAP mask. RN A observed that the CPAP water reservoir was empty and did not see the usual distilled water bottle on or near the nightstand. Instead of obtaining distilled water from the medication room as per her training and facility practice, RN A located a bottle labeled “purified water” under the resident’s refrigerator and used it to fill the CPAP reservoir. This bottle was later identified as hummingbird water, a mixture of tap water and granulated sugar that had been prepared by the family months earlier and stored near bird seed in the resident’s room. Video footage showed RN A searching for water, picking up a blue-labeled bottle from beneath the area of the camera, pouring its contents into the CPAP reservoir, and returning the bottle to where she found it. RN A acknowledged in interview that she knew purified water was not the same as distilled water and that she had been trained that distilled or sterile water was to be used in CPAP humidifiers. She stated she thought using purified water was acceptable because it was not tap water and reported attempting to clean the reservoir with water and tissues after being informed that the bottle contained hummingbird food. The respiratory therapist confirmed that CPAP humidifier water should be sterile or distilled and that she had initially set up the resident’s CPAP. Following discovery of the incident, the resident’s CPAP was taken out of service, and the resident was without CPAP use for at least one night. Medical providers, including the RT, MD, and FNP, described the situation as dangerous or potentially problematic if the sugar water mixture were used repeatedly, and the facility’s own policy specified that the humidifier chamber was to be refilled with fresh distilled water in the evening before use. These actions and inactions by RN A, and the presence of an unlabeled or misleadingly labeled container of hummingbird water in the resident’s room, led directly to the deficiency in providing safe and appropriate respiratory care. The deficiency also included the resident being without her prescribed CPAP therapy for at least one night after the machine was removed from service. The RT stated it was her understanding that the resident had been without CPAP for two nights, and the DON stated the resident went one night without CPAP after it was taken out of service and before a replacement machine was delivered and used. The resident herself reported that she did not wear her CPAP often and did not recall the incident. Nonetheless, the documented physician order required nightly CPAP use, and the care plan interventions were based on the resident’s severe obstructive sleep apnea. The combination of using an inappropriate fluid in the CPAP humidifier and the subsequent interruption of ordered CPAP therapy constituted the failure to provide respiratory care in accordance with professional standards and the resident’s care plan. Interviews with staff further clarified the circumstances leading to the deficiency. LVN B reported that she did not usually work on the resident’s hall and was unaware that hummingbird water was kept in the room. After being notified by the resident’s representative that hummingbird water had been poured into the CPAP, she entered the room, removed the CPAP from the resident, and took the hummingbird water to the medication room, noting that the room was somewhat dark and that the water appeared discolored. The DON stated that the hummingbird water bottle was not clearly labeled, that the water appeared cloudy, and that the facility sometimes used similar bottles for distilled water obtained from a supplier or grocery store. The facility’s policy on CPAP/BiPAP support required the humidifier chamber to be emptied, rinsed, and refilled with fresh distilled water in the evening, underscoring that the use of hummingbird water and the failure to ensure availability and correct identification of distilled water in the resident’s environment were central factors leading to the cited deficiency.

Two residents receiving O2 had flow rates set above their physician orders, and one resident’s tubing remained dated beyond the weekly change interval. Staff, including an RN and the DON, confirmed the mismatched flow rates and noted that tubing should be changed weekly by the RT. The facility policy required O2 to be administered per physician order and tubing/cannula to be changed weekly.
Oxygen Concentrator Left in Room After Order Discontinued: A resident with morbid obesity with alveolar hypoventilation and diabetes was observed with an oxygen concentrator at bedside even though there was no current oxygen order. The resident stated he used oxygen only when needed, and the CNO confirmed the oxygen had been discontinued earlier and the concentrator should not have remained in the room.
Missing Order for CPAP Use and Maintenance: A resident with sleep apnea and stroke had a CPAP in the room, but there was no physician order or care plan documentation for its use or maintenance. Staff knew the resident had the CPAP, yet CNAs and an RN reported they did not routinely clean the mask or tubing, and the LPN Resident Care Manager confirmed no order existed for the CPAP or its care.
A resident with a continuous O2 order was found without oxygen in place, and an LPN later said the order had been misread. Two other residents with COPD had respiratory equipment that was dirty or outdated, including a gray concentrator filter, tubing and water bottles dated weeks earlier, and tubing lying on the floor with visible dust. Staff gave inconsistent accounts of who was responsible for changing or cleaning the equipment, and the DON acknowledged the dirty equipment and old mask placed residents at risk for respiratory infection or pneumonia.
A resident with acute respiratory failure with hypoxia and severe cognitive impairment was ordered oxygen via NC at 2 to 5 LPM to keep O2 saturation at or above 95%. During observation, the resident was lying in bed with the NC on the side of the face instead of in the nose while the concentrator was set at 2.5 LPM. RN and DON stated the NC should be in the nose to deliver oxygen as ordered.
A resident with COPD and chronic respiratory failure did not receive oxygen at the ordered flow rate. Staff found the oxygen concentrator set below the ordered amount on multiple observations, and the resident stated the oxygen was supposed to be set higher. The DON, LVNs, and ADON acknowledged the setting was incorrect and that the ordered flow should have been followed.
Incorrect Oxygen Flow Rates and Delayed Tubing Changes
Penalty
Summary
The facility failed to provide respiratory care consistent with physician orders for two residents receiving oxygen therapy. Resident #5 had an order dated 1/7/2025 for oxygen at 2 liters via nasal cannula continuously for infiltrate of the left lung, but during observations on 7/7/2026, 7/8/2026, and 7/9/2026 the resident’s oxygen was running at 3 liters per minute. On 7/7/2026 and 7/8/2026, the oxygen tubing in Resident #5’s room was dated 6/26, and on 7/9/2026 Staff F, RN confirmed the tubing date and the 3-liter flow rate. Staff F stated the tubing should have been changed the prior week and that the resident was running at 3 liters despite an order for 2 liters. Resident #6 had a physician order dated 3/18/2026 for oxygen at 3 liters via nasal cannula continuously for chronic respiratory failure with hypoxia, but during observations on 7/7/2026 at 10:10 AM and 12:12 PM, and again on 7/8/2026 at 8:02 AM, the resident’s oxygen was being administered at 4 liters per minute. On 7/9/2026 Staff F, RN entered the room and confirmed the oxygen was at 4 liters, stating it should not be at that rate because the order was for 3 liters. The DON stated nursing staff should check oxygen flow rate every shift and as needed, and that tubing should be changed weekly by the respiratory therapist. The facility policy also stated oxygen tubing and mask/cannula are to be changed weekly and as needed if soiled or contaminated.
Oxygen Concentrator Left in Room After Order Discontinued
Penalty
Summary
Provide safe and appropriate respiratory care for a resident when needed was not maintained when the facility failed to remove an oxygen concentrator from Resident #12's room after the physician discontinued the oxygen order. Resident #12 was admitted and later readmitted to the facility with diagnoses including morbid obesity with alveolar hypoventilation and diabetes. On 7/7/26, the resident was observed sitting in his power chair with an oxygen concentrator at his bedside. When asked about oxygen use, the resident stated he only used oxygen when he needed it. Review of the resident's physician orders showed no current oxygen order, and the CNO stated on 7/8/26 that the oxygen concentrator should not have been in the room because oxygen had been discontinued on 6/17/26.
Missing Order for CPAP Use and Maintenance
Penalty
Summary
The facility failed to obtain physician orders for the use and maintenance of a CPAP for Resident 76, who was admitted in 6/2026 with diagnoses including sleep apnea and stroke. There was no documentation in the admission MDS or care plan showing that the resident used a CPAP. Observations from 7/6/26 through 7/10/26 showed the CPAP in the resident’s room on the nightstand. The resident stated that a friend brought the CPAP to the facility a day after admission, but staff did not clean the mask or tubing daily and the mask did not fit well. Staff interviews showed the CNA staff were aware of the CPAP but did not clean the mask or hose, one CNA reported washing the mask one time, and an RN stated she filled the chamber with water a few times but did not clean the mask or tubing. The LPN Resident Care Manager confirmed the resident did not have an order for the CPAP or for cleaning and caring for the equipment.
Respiratory Equipment Not Maintained or Applied as Ordered
Penalty
Summary
Resident #12 had an order for oxygen at 2 liters per minute via nasal cannula continuously, with titration up to 4 liters to keep oxygen saturations above 90% every shift. The resident’s care plan also directed staff to apply oxygen at 2 liters via nasal cannula. During an observation, the resident was up in a chair with no oxygen in place. The resident stated she had been wearing oxygen but was not sure when or why staff stopped applying it. The nurse later stated she had misread the order as oxygen could be applied only if saturations fell below 90%, and she acknowledged the resident did not wear oxygen despite the active continuous order. Resident #27 had diagnoses including dementia, COPD, anxiety, and shortness of breath, and her MDS indicated she required oxygen therapy. Her care plan directed staff to change oxygen tubing as needed and nebulizer tubing every week. During multiple observations, the resident’s oxygen concentrator filter was gray and dirty, and the tubing and empty water bottle were dated 5/24/26. The resident stated staff usually changed the equipment, but it had not been changed that she could recall. Later, the tubing and water bottle remained dated 5/24/26, and the concentrator filter was still dirty. Staff interviews reflected uncertainty about who was responsible for changing the equipment, and the ADON stated the tubing and water bottle should have been changed by 07/02/26, while the DON stated the dirty filter and old nebulizer mask placed the resident at risk for respiratory infection or pneumonia. Resident #9 had COPD and an order for oxygen at 2 to 4 liters per nasal cannula to maintain PO2 greater than 90%. The resident’s oxygen tubing was observed lying on the floor and had a piece of tape dated 06/22/26, with brown dust visible in the wheel-mark pattern on the tubing. The resident was unable to state when the tubing was last changed or how often it was changed. Staff interviews showed differing practices about changing oxygen tubing, with some stating it should be changed weekly or when dirty, while the DON stated she had been advised not to date the tubing and to change it when visibly soiled. The facility policy stated cannula or mask needed to be changed if it malfunctions or becomes visibly contaminated.
Oxygen Not Properly Delivered via Nasal Cannula
Penalty
Summary
The facility failed to ensure oxygen was administered in accordance with the physician’s order and facility policy for one sampled resident. Resident 44 was admitted with diagnoses including acute respiratory failure with hypoxia and encephalopathy. The MDS dated 5/28/2026 indicated the resident had severe cognitive impairment, was on oxygen therapy, and was dependent for eating, oral care, toileting, personal hygiene, showering, dressing, and footwear. A physician’s order dated 6/4/2026 directed oxygen via nasal cannula at 2 to 5 LPM to maintain oxygen saturation at or above 95% every shift, and the care plan was revised to reflect humidified oxygen via nasal cannula at 2 to 5 LPM to maintain oxygen saturation at or above 95% every shift. During a concurrent observation on 6/29/2026 at 10:33 AM, Resident 44 was observed lying in bed with the nasal cannula on the left side of the face while the oxygen concentrator was set at 2.5 LPM. During interviews, RN 3 stated the nasal cannula should be placed correctly in the resident’s nose for the resident to receive oxygen, and the DON stated the nasal cannula should always be in the resident’s nose to help maintain oxygen saturation at 95% and above. The facility policy titled Oxygen Administration stated oxygen is administered to residents who need it, consistent with professional standards of practice and comprehensive person-centered care plans, and under physician orders.
Incorrect Oxygen Flow Settings
Penalty
Summary
Provide safe and appropriate respiratory care for a resident when needed was not ensured for a resident with COPD, chronic respiratory failure, and functional quadriplegia. The resident’s care plan directed that oxygen be administered at 2 L/min via nasal cannula continuously to maintain SPO2 above 90%, and the physician order summary reflected oxygen at 2 L/min via nasal cannula continuously. However, during observation and interview on 06/30/2026, the resident’s oxygen concentration machine was set at 3 L/min, and the resident stated her oxygen was supposed to be set at 4 L/min. The LVN stated the resident was supposed to be on 4 L/min and adjusted the oxygen to 3.5 L/min, and the DON later stated the resident was to be getting 4 L/min and adjusted the setting to 4 L/min. A subsequent physician order dated 07/01/2026 directed oxygen at 4 L/min via nasal cannula to maintain SPO2 above 90%. During observation on 07/02/2026, the resident’s oxygen was again found set at 3.5 L/min. An LVN checking the setting stated it was at 3.5 L/min and that if physician orders were not followed, the resident could become short of breath and the orders would not be followed. The ADON stated the oxygen machine should be set with the ball meter at eye level, that if the order said 4 L/min it should be set on 4 L/min, and that 3.5 L/min was not good enough. The facility’s oxygen administration policy required verifying a physician order and adjusting the oxygen delivery device so the proper flow of oxygen was being administered.
