A respirator hose (10) for connection between a ventilator (32) and a breathing appliance (52) during respiratory therapy includes a tubular body defining a first lumen (26) for conveying a breathing gas from the ventilator (32), and a helical reinforcement member (14) with a hollow core coiled around the tubular body to define a second lumen (28) for conveying a second fluid in support of the respiratory therapy. The helical reinforcement member (14) has a configuration to resist kinking and crushing of the tubular body that would close-off flow of the breathing gas. A fitting (48) at one end of the hose (10) can be keyed to simplify connections between the lumens and fluid communication ports of the ventilator (32). |
