MR290 Chamber Overview

The Fisher & Paykel MR290 Auto-Fill Humidification Chamber is used with breathing circuits in hospitals and home humidifiers to deliver humidified respiratory gases. The MR290 Humidifier Chamber is compatible with F&P 850 System, AIRVO and AIRVO 2 Series, Bubble CPAP, and MR-series humidifiers. This provides optimal breathing therapy for invasive breathing circuits to non-invasive interfaces for infants to adults. The vented design can be used with rigid or semi-rigid water bottles or a tube adapter to connect with a water bag. Only fill the MR290 chamber with water that is USP sterile for inhalation or distilled water.
