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