Note:
The ventilator will not allow the operator to set a Peak Inspiratory Pressure (Insp Pres or PSV + PEEP, or baseline
pressure in APRV / BiPhasic, greater than 90 cmH
that the Ppeak > 90 cmH
to less than or equal to 90 cmH

Spontaneous breath

In adult and pediatric applications, a Spontaneous breath is a demand breath where the pressure level during
inspiration is preset at PEEP + 2 cmH
In neonatal applications a Spontaneous breath is a demand breath delivered only at the preset PEEP.
Note:
IF PSV level is insufficient to meet patient demand, premature termination of the breath may occur with auto-triggering.
In these cases the PSV level should be increased slightly.
Figure 3–12: PSV Waveform
In Figure 3–12 breath number 1 represents the flow tracing which occurs when the PSV level is insufficient to meet the
patient demand. Breath two shows resolution after increasing the PSV level slightly. (Pressure tracing will show a similar
appearance).
