Things to consider before placing the patient on HFOV
•
Hemodynamic status:
– The patient should be hemodynamically stable with a mean arterial pressure
of at least 75 mmHg
– If mean arterial pressure is less than 75 mmHg, consider fluids and/or
vasopressors to optimize the hemodynamic status before starting
the oscillator
•
Obtain ABG
– Ideally, pH should be greater than 7.2
– If pH is less than 7.2, consider correcting with a buffer for the transition
•
Patient's sedation status:
– You may need to consider sedation and neuromuscular blockades for
transition—due to the fixed Bias Flow of the device, patients are unable to
actively breathe and maintain a stable airway pressure and lung volume
– Once transitioned, patients may be able to be maintained on sedation only
