The high-frequency oscillations are overlaid

between the IMV breaths and the PEEP/CPAP
level in the expiratory time T
100 milliseconds before an IMV breath and
resume 250 milliseconds after the breath. The
pause following the breath is intended to allow
sufficient time to exhale and prevent air from being
trapped.
The , Pinsp, PEEP/CPAP, and T
insp
have an effect on IMV breaths.
Mean airway pressure is somewhat higher than
with high-frequency ventilation with CPAP due to
the IMV breaths.
However, during high-frequency phases, the
pressure oscillates at the PEEP/CPAP level again.
