TRIGGER
SENSITIVITY
(L/min) Inspiratory flow required to trigger the
ventilator to deliver a breath. 1 to 20 L/min
% O
2
Percentage of inspired oxygen of the gas
delivered to the patient. 21 to 100%
Accuracy:
±
3% full scale
NOTE:
It may take several minutes for the oxygen percentage to stabilize.
Other keys, knob, and indicators
APNEA PARAMS
key Allows the operator to select VCV or PCV (760 Ventilator only) apnea ventilation, and apnea
ventilation settings. Apnea ventilation is available SPONT mode, or in SIMV or A/C mode when
the respiratory rate is less than 6 /minute.* You can select an apnea interval from 10 to 60
seconds.* For other apnea parameter ranges, see mandatory VCV settings and mandatory PCV
(760 Ventilator only) settings.
* For ventilators equipped with software revision J or later.
MENU Allows you to view active and reset alarms, run SST and EST, adjust certain settings (including
endotracheal tube size, humidifier type*, date and time, apnea interval*, VCV flow (ramp or
square) pattern*, speaking valve setup*, alarm volume, PCV timing, and volume bar graph
display), access oxygen sensor functions (calibrate, enable or disable % O
2
alarm limits, and
enable or disable display of oxygen sensor reading), enter standby mode, and view battery
information, display software revision, display service information, and enter EasyNeb nebulizer
functions. (The
700 Series Ventilator System Operator’s Manual explains how to use the menu
function.)
* For ventilators equipped with software revision J or later.
100% O
2
Switches the % O
2
to 100% for 2 minutes, then returns to the current % O
2
setting. The 2-minute
interval restarts every time you press 100% O
2
. Once the 100% O
2
has started, you can press
CLEAR to stop the maneuver (unless you have entered a MENU key function or selected a
setting).
MANUAL INSP Delivers one mandatory breath to the patient according to the current mandatory settings (in
A/C or SIMV) or the current apnea parameters (in SPONT). You can deliver a MANUAL INSP at any
time during the exhalation phase of a breath as long as the exhaled flow is less than 30% of the
peak exhaled flow, except during apnea ventilation.
EXP PAUSE
(760 only) Allows you to measure the patient’s auto-PEEP. Pressing EXP PAUSE causes the ventilator to close
the exhalation valve at the end of the expiratory phase, and does not deliver the next mandatory
breath. At the end of the maneuver, the message window shows the calculated value for
auto-PEEP (expiratory pressure at the beginning of the maneuver minus expiratory pressure at
the end of the maneuver) and total PEEP for 30 seconds.
The message window shows the end expiratory flow in L/min at the beginning of each breath. If
there is expiratory flow when the ventilator delivers the next breath, indicates that auto-PEEP is
present.
The EXP PAUSE continues as long as you hold down the key, and should last only as until
expiratory pressure stabilizes. An EXP PAUSE maneuver ends when you release the key, the
patient initiates a breath, an alarm occurs, the expiratory phase (including the maneuver) lasts
more than 20 seconds, or the ventilator detects a leak.
Auto-PEEP:
Range: 1 to 35 cmH

O.
Accuracy:
±
(1 cmH

O + 3% of reading).
