Breath timing
RATE (/min)
Shows the calculated value of the total
respiratory rate, based on the previous
60 seconds or 8 breaths (whichever interval is
shorter). Updated at the beginning of each
breath. (Default breath timing display.)
The calculation is reset (and display is blank)
when ventilation starts, when apnea
ventilation starts or autoresets, when you
change the mode, breath type, or
RESPIRATORY RATE setting, and when you
press the alarm reset key.
1* to 500 /minute
Accuracy:
±
(0.1 +1% of reading)/minute
* For ventilators equipped with
software revision J or later.
I:E RATIO
Shows the ratio of measured inspiratory time
to measured expiratory time. Updated at the
beginning of each breath.
1:99.9 to 9.9:1
Accuracy:
±
(0.1 + 2%)
INSP TIME (s)
(760 only)
The measured inspiratory time, including
breaths that are truncated due to a
HIGH PRESSURE alarm. Updated at the
beginning of each expiratory phase.
0.00 to 9.90 seconds
Accuracy:
±
0.05 seconds
Volume
EXHALED
VOLUME (ml)
Shows the patient’s measured expiratory
tidal volume averaged over the last 5 breaths
(for A/C VCV breaths, ventilator-initiated PCV
breaths, and PCV apnea breaths) or for the
just-completed breath (for all other breaths).
Corrected to BTPS and compliance-
compensated. Updated at the beginning of
each inspiration. (Default volume display.)
The calculation is reset when ventilation
starts, when apnea ventilation starts or
autoresets, when you change the mode,
breath type, or any setting that affects
breath averages (for example, respiratory
rate or inspiratory time), and when you press
the alarm reset key.
0 to 9 L
Accuracy:
±
(10 ml + 10% of reading)
TOTAL MINUTE
VOLUME (L)
Shows the patient’s measured expiratory
minute volume, based on the previous
60 seconds or 8 breaths (whichever interval is
shorter). Updated at the beginning of each
breath.
The calculation is reset when ventilation
starts, when apnea ventilation starts or
autoresets, when you change the mode or
breath type, and when you press the alarm
reset key.
0 to 99 L
Accuracy:
±
(10 ml + 10% of reading)
DELIVERED
VOLUME (mL)
(760 only)
Shows the measured inspiratory tidal volume
for the just-completed PCV or PSV breath.
Corrected to BTPS and compliance-
compensated. Updated at the beginning of
each inspiration.
0 to 3000 ml
Accuracy:
±
(10 ml + 10% of reading)
