Philips internal reference (b)(4).A caregiver reported that his son required two emergency room (er) visits for breathing treatments within the same week, and was treated and released each time due to asthma and bronchitis.A physician alerted the caregiver during the second visit that the filter on their optionhome compressor was very dirty, and that his son was inhaling dust from the filter.The caregiver reported the filter had not been changed for four years.From the latest available information the filter has been replaced, the patient is still using the device, and is recovering.The device was not returned to the manufacturer for evaluation.The instruction for use for this compressor states "check the filter at least once a week.Replace the filter when dirty" and "the filter should be replaced when it becomes discoloured".Based on the information available, the manufacturer concludes that user misuse/mishandling was the cause of the event, and that no further action is necessary.
