Classification • Electrically powered – internal battery powers Vent Inoperative & audible alarms if AC power lost. Error code 205 if internal low battery condition. • 2 modes • CPAP • S/T • Set Rate • IT in seconds • IPAP • EPAP
Circuit • BiPAP circuit (with exhalation port or Whisper Swivel) • Humidifier or HME • With heated humidifier need circuit with water traps. Cannot cut into regular BiPAP circuit to add traps.
Start Up • Plug into AC mains & Connect to 50 psi gas source • Connect BiPAP circuit - don’t cap • Power switch RU corner on back panel – ON Dispos-able inlet filter O2 module Fuses
Follow steps on screen, block circuit, “Start Test”. Exhalation (castle) port
Exhalation Port Test • Analyzes leak rate of exhalation port • If successful – the value of “Pt. Leak” will be displayed • If unsuccessful – “Tot. Leak” will be displayed • EPT must be performed when using the Plateau Exhalation Valve because the leak is significantly different than the port or swivel.
Test Complete, press Monitoring to exit. Monitoring
Pressure Flow Trigger Criteria in S/T • Time Trigger (Rate) • Flow Trigger • 6 ml inspired volume detected • Patient flow exceeds the shape signal (a shadow of the flow signal delayed by 300 ms)
In S/T mode • Only patient (flow) triggered breaths are flow cycled (PS). • Time triggered breaths are time cycled according to the set Inspiratory Time.
Pressure Flow Cycle Criteria in S/T • Time cycled • Set Inspiratory Time • A 3 sec maximum IPAP time has occurred • Flow cycled • Flow reversal detected • Patient flow is less thansignal flow • Spontaneous Expiratory Threshold achieved – another way to flow cycle SET
