Another benefit of the microprocessor-based technology is
the ability to store data and to present it in multiple formats.
Trend screens are now an integral component of most
present- day mechanical ventilators and enable the clinician
to follow changes over time and even to reconstruct past
clinical events.
Trend screens may present both graphic and numeric data.
Ventilatory parameters can be displayed in a graphic format
over several hours or numerically on a minute-by- minute
basis. A typical trend screen is shown in Fig. 5.1 . The upper
half shows hourly graphic trends for four selected ventilator
parameters. The lower half lists selected parameters in tabular
form from minute to minute. All of the parameters may be
changed, and the clinician can scroll through the screen to
find times of interest. Although this may seem obvious, trend
screens are of no value if they are not customized by the user
to display values of interest for a particular patient. Most
ventilators allow trending of far more parameters than are
used in the neonatal intensive care unit (NICU), because so
many of the current devices are “cradle-to- grave” single platform
machines. Indices useful for adult intensive care may be
meaningless in the NICU, and the default screen rarely is
useful.
