General information
Puritan Bennett™ 700 Series Ventilator System Service Manual 10070389 Rev. A 1-27
1.11.2 Patient Data
The PATIENT DATA section of the keyboard allows you to view the pressure, breath timing,
and volume of the patient’s breath. You can also view or change the alarm settings. A lighted
key indicates that a measurement is selected, and its value appears in the display window.
Values are continuously displayed and updated during ventilation.
Table 1-11 summarizes the functions of the keys and indicators in the PATIENT DATA section
of the keyboard.
APNEA PARAMS
indicator Lights when apnea ventilation is active.
Lights with PROPOSED indicator when you are setting apnea parameters, and both indicators
turn off once apnea parameters are accepted.
Message window Shows up to four lines of information (20 characters per line).
First line : Reserved for the highest-priority active or autoreset alarm. On the 760 Ventilator and
for 740 Ventilators with software revision H or later, if no alarm is active and the display of the
oxygen sensor reading is enabled, the % O
2
is displayed here. If VCV is the current or proposed
breath type, the VCV flow pattern is also displayed if there are no active or autoreset alarms.
Second line : Information about the menu function or settings, alarm silence time remaining, or
current date and time. On the 760 Ventilator and for 740 Ventilators with software revision H or
later during normal ventilation, shows “
Flow (L/min) .”
Third and fourth lines: Reserved for other messages. On the 760 Ventilator and for 740
Ventilators with software revision H or later for every breath type, peak and end inspiratory
flows are displayed on the third line, and end expiratory flow is displayed on the fourth line
(except that inspiratory flow is not displayed during VCV breaths or VCV apnea ventilation).

Pressure
MEAN PRESSURE Shows the calculated value of ventilator
breathing circuit pressure over an entire
respiratory cycle. Updated at the beginning
of each breath. 0 to 99 cmH

PEAK PRESSURE Shows the maximum pressure measured
during inspiration. Updated at the beginning
of each expiratory phase. (Default pressure
display.) 0 to 140 cmH

PLATEAU
PRESSURE
(760 only) Shows the pressure measured at the end of
the plateau period of a mandatory
inspiration (whether the inspiration is in a
regular VCV breath or is part of an
inspiratory pause maneuver). Updated at the
beginning of each expiratory phase. The
PRESSURE display shows a blank if the
ventilator does not detect a stable plateau
pressure. 0 to 140 cmH
2
O (0 to 140 hPa)
Accuracy:
±
(3 + 4% of reading) cmH

PEEP/CPAP
(760 only) Shows the pressure measured at the
expiratory limb before any inspiratory effort.
Updated at the beginning of each inspiratory
phase. 0 to 140 cmH
