5.5 The 100% O 2 and MANUAL INSP keys
Once ventilation begins
The 100% O 2 key delivers 100% oxygen to the patient for 2 minutes
at any time except during apnea ventilation. Pressing CLEAR at any
time after the 100% O 2 maneuver begins cancels the maneuver and
the oxygen concentration returns to the set % O 2 .
1. Press 100% O2 : The key lights and
delivered oxygen concentration
increases to 100%.
2. Once the oxygen concentration
reaches 100%, a 2-minute timer
starts and the ventilator delivers
100% O2 to the patient. Pressing
the 100% O2 key again restarts the
2-minute timer.
3. When the 2-minute interval has elapsed, the 100% O 2 key light
turns off and the oxygen concentration returns to the set % O 2 .
NOTE:
The displayed EXHALED VOLUME for the first breath after you
press the 100% O 2 key may be higher than the actual volume
exhaled from the patient. The high displayed volume is a
result of an initial flush of the ventilator with 100% O 2 and
does not reflect actual volume delivered to the patient.
The MANUAL INSP key delivers one
mandatory breath to the patient
according to the current settings (in
A/C or SIMV mode) or the current
apnea settings (in SPONT mode).
You can deliver a MANUAL INSP at
any time during the exhalation
phase of a breath. (To deliver a
7-00086
MANUAL INSP, 200 ms of the exhalation phase must have
elapsed, and expiratory flow must have decreased to 50% of
peak inspiratory flow. If you press INSP PAUSE during SPONT
mode, a manual inspiration is delivered when 200 ms of the
exhalation phase have elapsed, and expiratory flow is less than
2 L/min for 50 ms) MANUAL INSP is not functional during apnea
ventilation.
