A portable collection of devices intended to be connected to a medical gas supply to assist noninvasive ventilation (i.e., without an artificial airway) using continuous positive airway pressure (CPAP) during spontaneous patient respiration in respiratory emergency situations and/or respiratory therapy settings. It includes an in-line/gas-line CPAP device (a small plastic unit intended to establish a gas pressure proportional to gas flow rate), a face mask, a nebulizer, and may include additional components (e.g., manometer, flowmeter, tubing, mask strap). This is a reusable device once the consumable products have been replenished.
