The Drive DeVilbiss iGo2 Portable Oxygen Concentrator is indication of supplemental oxygen. The device is not intended for life support, nor does it provide any patient monitoring capabilities.

The proposed Drive DeVilbiss iGo2 Portable Oxygen Concentrator (POC) is similar to the predicate devices, pressure-vacuum swing adsorption based on molecular sieve technology using two containers filled with molecular sieve (sieve beds). Ambient air is drawn into the concentrator via a piston style compressor and compressed into a single sieve bed. As pressure increases nitrogen is adsorbed and concentrated oxygen exits one end of the bed and is collected in a product tank. Simultaneously in the other sieve bed, nitrogen is desorbed as the pressure decreases to a vacuum and is exhausted into the atmosphere. Once the pressure or vacuum reaches a defined maximum a valve switches the compressor connections to the sieve beds. The sieve bed previously connected to the pressure head will be connected to vacuum. The oxygen collected in the product tank is then dispensed to the patient upon detecting a patient inhalation, much like an oxygen conserving device. The proposed Drive DeVilbiss iGo2 POC provides pulse dose oxygen in the same manner as primary predicate device (DeVilbiss Model 306 POC, K081468). The "Smart Dose" feature has been added to the proposed device, which is substantially equivalent to the feature in the reference device (Model 350G gas conserver, K090421). Smart Dose will automatically increase the patient's prescription setting by one if the system determines the patient has increased rate of breathing.

The DeVilbiss Healthcare DV6WM Wireless Modem is intended to be used as a data collection tool for DeVilbiss IntelliPAP Series with SmartLink II Bluetooth module, IntelliPAP2, and DeVilbiss Blue Series CPAPs for patients in a home or healthcare environment. It is not intended to be used as a diagnostic tool.

The proposed DeVilbiss DV6WM Wireless Modem is an accessory to a DeVilbiss CPAP machine. The proposed device provides automatic wireless telemetry of CPAP usage and performance data to a healthcare provider.

The DeVilbiss Intellipap2/DeVilbiss BLUE Series is intended for use in treating OSA in spontaneously breathing patients 30 Kg (66 lbs) and above by means of application of positive air pressure. The Device is to be used in Home and Healthcare Environments.

The proposed DeVilbiss Intellipap2/DeVilbiss BLUE are devices for treating obstructive sleep apnea by means of applied airway pressure. Predicates devices DeVilbiss IntelliPAP DV5 Series (K071689), and Respironics, Inc, Remstar Auto A-Flex HT (K113068) operate by the same basic principal of creating pressurized air that is delivered to the patient's airway by a nasal or oralnasal mask. The devices maintain a set pressure, prescribed by a physician, at the patient's mask for flow rates up to approximately 100 L/m.
