3100B HFOV quick reference card 3  4 1 2 5  Controls at a glance 1. Bias flow: Set this control first • A typical range for the adult is 25 to 40 lpm • Adjusting bias flow will affect mean airway pressure Lowering bias flow may decrease work of breathing and facilitate weaning  2. Adjust: Sets the mean airway pressure • This control directly affects gas exchange • Initial setting is slightly higher than conventional ventilation  3. Power: Controls piston displacement (tidal volume) • Initial setting is based on chest wall movement • Movement should be visible from chest to upper thigh • Adjust to achieve optimal PaCO2  4. Inspiratory time %: 33% for most applications • For some patients, increasing inspiratory time % to 50 may improve ventilation and increase lung recruitment • Once set, this control is not typically changed  5. Frequency: Breath rate is expressed in hertz (Hz) • One hertz equals 60 breaths per minute • An initial setting of 5 to 6 (Hz) is typical • A decrease in frequency = increased tidal volume • A decrease in frequency = increased minute ventilation • Frequency is not typically changed during HFOV
