Aqua Pak® Prefilled Humidifier Kit with 340 mL of sterile water. The kit includes a 000-40 Humidifier Adaptor (Sterile). Humidifier adaptors incorporate an audible alarm to alert clinicians to flow restriction or occlusion of humidifier or tubing. The reservoir bottles have built-in oxygen tubing connectors and the humidifier’s micro-diffuser produces smaller bubbles and greater surface agitation for quiet operation and high humidity output. Individually packaged, 20/case.
