INTRODUCTION: Humidified High Flow Nasal Cannula (HHFNC) application is often implemented in critically ill patients presenting with respiratory distress to provide a less invasive means of support. Interruption of HHFNC therapy during transport has been implicated in detrimental patient outcomes. Our objective was to develop a practical system for patient transport with our HHFNC. METHOD: The HHFNC system included a calibrated air entrainment device (Maxtec OptiVenturi, Salt Lake City, Utah) connected to a 50psi oxygen source which provided 40% oxygen at 50 lpm to the humidifier (Fisher & Paykel MR 850, Auckland, New Zealand) attached to a small high flow cannula (Fisher & Paykel Optiflow, Auckland, New Zealand). The humidifier was plugged into AC power through the Uninterruptible Power Supply (UPS) battery (Leviton U1500-OSK, Little Neck, NY) until heated and humidified to 37âC in the invasive mode. The UPS was then disconnected from AC power providing DC power to the humidifier and was run to depletion. RESULTS: The UPS was able to power the humidifier for an average of 67 minutes (n=3; SD 0.58) while maintaining a constant temperature of 37â C (SD 0.16) at 50 lpm of 40% oxygen. CONCLUSIONS: In this model, a UPS with a pure sine wave was required to produce a recognizable current to power the humidifier. Our project demonstrated that this system was able to provide more than an hour of usable time while consistently maintaining a temperature of 37â C, creating a viable, practical and portable option for HHFNC transport.
