The list of all possible ventilation parameter settings on the Main screen include the following:
+ only available on the HT70PM when the on-airway flow sensor is in use

Note:
When an on-airway flow sensor is detected, both the Flow Trig and Ptrig settings are active, and the first
available detection of patient effort (either flow or pressure) will trigger a breath.

Note:
For Volume Control mandatory breaths, VT, flow, and i-time are available to be set. The VT (tidal volume) is
the controlling setting. Flow and i-time setting are inversely related to each other. Changing either flow or
i-time causes the inversely related setting to be recalculated to match the new flow or i-time setting and
the VT remains steady.
For example, if the flow rate is changed to a higher setting, the i-time will decrease to meet the new flow
setting. If the i-time is changed to a longer time period, the flow rate will decrease to meet the new i-time
setting.
Also while in Volume Control, changing the flow waveform setting on the More screen will cause the flow
to change on the Main screen. A square wave will use a lower flow, and a descending ramp waveform will
use a higher flow. Always recheck the settings and monitored values after changing the flow waveform.
