5.1 Hematocrit Limit - (Hct Limit)

PROFILE
START UP
NOTE: See the Tech Notes Section on Hypovolemia for additional information on
this subject.
The Hct Limit feature provides a way for the clinician to be alerted via an audible
and visual alarm when the patient's hematocrit has reached a pre-selected hematocrit
limit level.
Prior to setting a hematocrit limit, the user should fully understand this subject (see
the Tech Notes Section on Hypovolemia).
A hematocrit limit can be set and/or changed at any time during the monitoring
process.
When viewing the START-UP
screen prior to the automatic change
to the PROFILE screen, the HCT
LIMIT block will blink and display
asterisks instead of numbers.
The Hct Limit that is typically set for
any given patient is one or two Hct units
below the hematocrit at which that
patient experiences morbidity (i.e.
nausea, vomiting, lightheadedness, etc),
thereby providing a comfortable
"margin of safety" for the patient run.
The Hct Limit can be set by pressing the
up or down arrow keys. The Hct Limit
can never be set below the starting Hct
or the current Hct level, whichever is
higher.
