General

 

  • Single use disposable device for research use on mechanically ventilated patients
  • Optimized for ventilator use either inline or on ventilator exhaust port
  • Created to provide a better alternative for researchers using the original RTube™ in ventilator applications RTubeVENT Difference
  • Replaces the resistive one-way valve in the standard RTube with a free-flowing bi-directional design
  • Clear 15mm diameter flow path straight through device with no valves, restrictions, or moving parts
  • Matched to the flow and pressure parameters of the ventilator
  • Uses the same cooling sleeve as the standard RTube
  • Can be used in any orientation – upside down, sideways, angled
  • Interfaces seamlessly with standard 22mm tapered connections found on most breathing circuits Example of RTubeVENT Flow Charcteristics
  • Example Test performed at Exhaled Breath Research Lab, Virginia Commonwealth University School of Nursing, using a Puritan Bennet 840
  • Ventilator Self-Test sequence run with standard circuit
  • RTubeVENT placed in-line on exhalation limb of circuit
  • Self Test sequence run again
  • Both test series passed
  • Conclusion: This ventilator functioned normally with the RTubeVENT in the breathing circuit
