7.3.4.1 Trends
NOTE:
In setting up trends, you can choose among the para-
meters shown in the two monitored parameter win-
dows, with these additions:
• To trend Ppeak, Pmean, and PEEP/CPAP, select
Pcombi; this causes all these pressure values to be
trended together.
• To trend fTotal and fControl, select fcombi; this
causes both rate values to be trended together.
• You can also trend the Pinsp parameter.
• An additional trending for Oxygenation is available
in INTELLiVENT
®
-ASV.
• With the Masimo Rainbow SpHb monitoring option,
the Trend graph varies depending on the selected
mode. See Appendix F, Pulse oximetry.
To show monitored parameters, select 1 hr, 3 hrs, 12 hrs,
24 hrs, or 96 hrs trends. After you select the time value, you
will see the trend displays (Figure 7-9), including all data since
you switched on the ventilator or for the past time value you
entered.
From the time start ventilation, the device continually stores
the monitored parameters in memory, so you have access to
any of this data, even after standby. The data disappears from
the device’s memory when power is switched OFF or
New
Patient
is selected.
Alternatively, the freeze and cursor measurement function can
be used to examine points on trend waveforms. When trends
are frozen, the time axis displays elapsed time relative to the
present.
