Designed to add humidity to inspired gas, preventing the drying and irritation of the respiratory mucosa. The humidifier features a micro-diffuser that produces smaller bubbles and greater surface agitation, allowing for quiet operation, therapeutic humidity output, and greater patient comfort. Prefilled reservoir bottles have built-in oxygen tubing connectors. Humidifier adapters have a built-in alarm that is easily heard when tubing becomes occluded or air flow is restricted. Individually packaged.
