|
Parameter |
Initiation settings |
|
|
|
|
FiO2 |
Same FiO2 that patient was receiving during conventional ventilation, adjust to SpO2 > 90% |
|
Mean airway pressure (mPaw) |
3–5 cmH2O higher than patient was receiving during conventional ventilation, titrate upward to reduce FiO2 below 0.6 |
|
Bias flow |
40 l/min, titrate to exceed any spontaneous inspiratory efforts |
|
Pressure amplitude of oscillation ('power' or ΔP) |
Titrate to produce a 'wiggle', or body movement, from shoulders to midthigh |
|
Frequency |
5 Hz, then titrate to PaCO2 |
|
Percentage inspiratory time |
33% |
