DeVilbiss Model DV5x Series CPAP with Heated Humidifier Device is intended to treat Obstructive Sleep Apnea (OSA) in patients weighing 30 Kg and above. The device creates a positive pressure in the patient's airway to prevent collapse of the airway while the patient is sleeping. The heated humidifier provides additional humidity to the air supplied to the patient. The heated humidifier has a removable water chamber for filling with water and ease of cleaning.

Some units were manufactured with a defective humidifier chamber o-ring. Unit could leak, allowing water to escape during use, causing damage to furniture.

The firm, DeVilbiss Healthcare, issued a "URGENT: MEDICAL DEVICE CORRECTION" letter dated March 11, 2011 to its customers. The letter described the product, problem, and actions to be taken.
